From the module's front panel This approach is designed for those with experience in programming directly on the modules. Note: Only possible in LD mode

From the Zelio Soft 2 programming workshop This approach is designed for people with experience using the programming software workshops commonly used in automation.



Languages Used

Zelio Soft 2 software provides 2 programming modes:

These languages implement:

Ladder language Ladder language (LD) is a graphic language. It can be used to transcribe relay diagrams, and is suited to combined processing. It provides basic graphic symbols: contacts, coils, blocks. Specific calculations can be executed within the operate blocks. Example of a program in ladder language

LD mode: Ladder language

FBD mode: Function Block Diagram

Predefined function blocks:

Timers,

Counters.

Specific functions:

Time management,

Character string,

Communication, etc.



FBD mode FBD mode allows graphic programming based on the use of predefined function blocks. It offers a large range of basic functions: timer, counter, logic, etc. Example of a program in FBD.

Operating Mode

There are two operating modes for the Zelio Soft 2 programming workshop:

Data entry mode Data entry mode is used to construct programs in LD or FBD mode, which corresponds to the development of the application.

Debug mode This mode is used to finalize the application and can be carried out:

In these two modes, it is possible to:

In simulation mode: the program is executed offline directly in Zelio Soft 2 (simulated on the PC). In this mode, each action on the graph (changing the state of an input, output forcing) updates the simulation windows.

In Monitoring mode: the program is executed on the Zelio module, the Zelio Soft 2

programming workshop is connected to the module (PC module connection). The different windows are updated cyclically.

Display in dynamic mode (in the windows: Edit / Supervision / Front Panel), the output states and program function blocks corresponding to the wiring sheet.

Force the inputs/outputs to test program behavior under specific conditions.



Creating an Application

Description

This is an important phase, as it determines the future configuration of the work environment. The available functions depend on:

These choices enable configuration of the programming workshop:

The hardware configuration (module/extension),

The type of programming language selected (LD/FBD).

LD/FBD context for the menus,

Composition of the windows.

Choice of module/Programming type

This function is used to modify the module and/or extension type when an application is open in edit mode. If the user also modifies the operating mode of an application open in edit mode, then the current application must be closed and a new application created (user program). It may also be used to create a new application when no application is open in edit mode, in the same way as with the File|New command. This function displays a suite of three screens:

For an application in FBD mode For each module type (+ extensions where applicable) there is a drawing background displayed in the Edit window with I/Os specific to the type chosen arranged about its periphery and a specific set of FBD functions presented in the Function bar. The names of the module and extensions are displayed below the wiring sheet. For an application in LD mode For each module type (+ extensions where applicable) there is a specific set and number of LD functions presented in the Function bar. The names of the module and extensions are displayed below the wiring sheet.

The first one presents a photo of each category of module (extendable, without display, etc.). If you click on a photo, then underneath the photo you will get a display of each type of module in the category, together with the characteristics. Clicking on the name of one of these module types will select the type and it will be displayed in the last grid of the window. If there are extensions, then Clicking on next will bring up the second screen.

The second screen, where applicable, shows each extension type available for the previously selected module type. To select an extension and, if there are several programming modes for the application, switch to the third screen, proceed as above.

The third screen is used, where applicable, to select the programming type used for the new FBD or Ladder LD application (default type) by clicking on the drawing representing the type of network imaging the programming.

How to Debug an Application without Loading it onto the Module: Simulation

Description

To ensure that a program will do what the user wants before loading it onto a Zelio2 module, it is possible to simulate execution of the program using the ZelioSoft2 workshop. This simulation allows the user:

To temporarily modify or permanently force any FBD function output, any LD contact, the majority of function parameters as well as any of the keys on the module front panel,

Then to view the effect of each modification or forcing on the execution of the program by observing the values of the FBD block outputs, LD contacts and coils as well as the displays on the simulated module front panel.

How to Execute a Program in Simulation Mode

After having created a diagram in the wiring sheet (Edit window) or using "Zelio entry" in LD mode, simply click on the S icon in the toolbar.

It is possible to return to Edit mode by clicking on the icon. After clicking on the "S" icon, the "simulation mode" toolbar and a set of icons representing the functions available in simulation mode are displayed. All or some of the following windows can be displayed in the ZelioSoft2 workshop window:

Using the window menu:

The Edit window,

The Supervision window,

The Module Front Panel Simulation window.

Using the icons in the bar at the bottom of the window:

The Simulation time window,

Reading, writing, comparing and clearing the module program,

Monitoring,

Modifying communication parameters,

Modifying the configuration parameters of the user program.

Simulation Mode Toolbar

The simulation bar is used to modify simulation rates or to simulate certain events affecting the Zelio 2 module.

Note: To display all the functions described below, in the File|Preferences menu check the



As the execution of the application on the module is periodic and controllable by a WATCHDOG (program configuration window | configuration tab ), the programming workshop can call the simulator periodically and require that the simulator use a time base that increments the number of milliseconds corresponding to the application's execution period (application basic cycle ). This time base will set the rate not only for execution of all functions that depend explicitly or implicitly on time (timers, Filtered FBD inputs, looped FBD functions, etc. ) but also changes in the clock and the simulator date on which Clock, Daily programmer and the Summer/Winter time functions depend. Thus, if one wishes to highlight all of the transient problems introduced by the user program, the user program must be executed period by period. The Number of cycles must be set to 1, which will trigger a duration between 2 simulation results equal to the execution period of the application on the module. On the other hand, to provide a succinct explanation of the application's operation, it is possible to raise the number of cycles to 255. If this is not sufficient, then the "Acceleration and simulation limits" window can be used to multiply this duration up to 65000, or at least 46 hours between 2 simulation results. Other icons and windows:

A gray button cannot be used; a colored button can be activated by clicking on it once; a yellow or red key indicates a stop in the simulation (pause) or a stop in the simulated module (stop or power failure). A green key indicates a program whose simulation is in progress (Run). When run is clicked, the switch from stop red to run green triggers initialization of the user program and startup of program execution simulation. When stop is clicked, the change from run green to stop red triggers the stop of program execution simulation. The "pause" key in the simulation bar can be used to stop and restart program execution. This key can only be used in simulation mode. The "power outage" key in the simulation bar can be used to stop and restart a warm restart initialization and then program execution. This initialization, which takes into account the state of all latching parameters, is only executed on the module when a power failure occurs. This key can only be used in simulation mode. The refresh frequency corresponds to the frequency with which the output and parameter values are updated in the application windows that are open during simulation mode. The update of this set of values is considered to be the simulation result. The refresh frequency can be used, in the absence of the step counter function, to slowly display the transient changes of the simulated application. The integer Number of cycles is the number of cycles executed between each simulation result. A number of cycles equal to 1 signifies that all the modifications to the input output states displayed correspond to period by period execution (application execution period defined in the configuration) of the module chosen. Management of the date and time is aligned on the number of cycles executed between each simulation result. If the user selects a number of cycles that is greater than 1, in this case, each refreshing of simulation results, he/she cannot observe the changes in the inputs outputs of functions carried out during a shorter period.

Display the refresh period box and specify the number of cycles for monitoring and simulation. All the functions described below are required to carry out a simulation capable of highlighting all of the transient problems, in particular upon startup of the application and when power is restored following a power failure.

Stop, Pause and Power failure,

Run,

The refresh frequency of the PC windows (modifiable values).



For example, if the user simulates the following program with a Number of cycles value = 2, he/she will not see the B00 block output move because it switches from ON OFF at every cycle. Only the Number of cycle = 1 value enables every switch in this output to be observed. To quit simulation mode, simply click the "edit" key in the toolbar .

How to Monitor and Modify an Application Running on the Module from the Programming Workshop: Monitoring

Description

To remotely monitor or modify the behavior of a program running on a Zelio 2 module, the user can use the monitoring function. This monitoring allows the user:

These modifications and display are carried out:

The current value of each link is displayed near the function block output. Monitoring mode is independent of the "Run/Stop module" function. If the module is stopped, only modifications to the parameters and the outputs of the buttons on the module front panel are displayed.

To temporarily modify or permanently force any FBD function output, any LD contact, the majority of function parameters as well as any of the buttons on the module front panel,

Then to periodically view execution of the program by observing the values of the inputs and outputs of the module and its extensions, FBD block outputs, LD contacts and coils, the current state of parameters as well as the displays on the front panel of the connected module.

On the one hand in the ZelioSoft2 programming workshop windows, which can be accessed:

This shows the state of the module's inputs and outputs, as well as those of its possible extensions, the states of the program, the FBD function block inputs/outputs and parameters (including output parameters), the states of the LD contacts and coils and the parameters of the LD diagram corresponding to the program running on the module.

Using the window menu: Edit, Supervision, on the module front panel,

Using the icons at the bar at the bottom of the monitoring window (LD only): Function blocks, Discrete inputs, Zx keys, Discrete outputs.

And on the other hand, in the monitoring mode toolbar, where a set of icons can be used to start and stop application execution in the module and the frequency at which output values and parameters are updated in the open application windows.

Note: Monitoring mode cannot be considered as a dependable debugging method, because on the connected module that switches to monitoring mode, the application execution periods (defined in Program configuration) are extended by the periods of communication time between the PC and the module and periods of possible permanent forcing applied to the application. No guarantee can be made concerning the real duration of cycle times during this operating mode. Besides, during this operating mode, the WATCHDOG action (defined in WATCHDOG Program Configuration) associated with the application is deactivated. In addition, when applications without permanent forcing are executed, the application may run on the module for a time that is much shorter than the refresh period for the PC monitoring windows. The actions observed on the module are therefore not less than twice the monitoring screens refresh period (Shannon sampling rule).

Switch to Monitoring Mode in the Module and Programming Workshop

The programmer can only switch to this mode if the module:

Contains a program in which parameters modification is not read/write protected by a



The HMI checks whether a password protects the program and parameters or the module parameters. If this is the case, the HMI displays the Password dialog window. The chart in the Edit window must be in accordance with the module program. The HMI starts the "Compare the module data with the program" function. If a difference exists, the HMI returns to edit mode. Following these checks, simply click on the "magnifying glass" button in the toolbar to switch to monitoring mode. After this action, the following is displayed:

This shows the state of the module's inputs and outputs, as well as those of any extensions, the states of the program, the FBD function block inputs/outputs and parameters (including output parameters), the states of the LD contacts and coils and the parameters of the LD diagram corresponding to the program running on the module.

In monitoring mode, the following functions are not available:

Graphic editing of the program,

Reading, writing, comparing and clearing the module program,

Monitoring,

Modifying communication parameters,

Modifying the configuration parameters of the user program.

Monitoring Mode Toolbar

The refresh frequency corresponds to the frequency with which the output and parameter values are updated in the application windows that are open during monitoring mode. Diminishing this frequency, and consequently the refresh period, reduces the ZelioSoft2



programming workshop workload that monopolizes the PC to the detriment of other system or user programs. The commands that can be used to control monitoring are:

The Stop button,

The Run button,

The time between 2 displays of module data on the screen (modifiable value).

Note: To display the refresh frequency described below, check the following box in the File|Preferences menu: Display the simulation and monitoring refresh period. Modification of the refresh frequency is essential in order to limit the time allotted to the ZelioSoft2 programming workshop by the Windows system. This is because in older Windows systems or small PC configurations, the load represented by the workshop in monitoring mode substantially slows down other applications running in parallel or system operations.

How to monitor and modify and application using the module front panel

Description

See the MONITORING Menu

What the error code displayed on the front panel of the controller means

Description

It is possible to display on the LCD screen the errors or warnings detected by the firmware of the module (WATCHDOG overflow, cycle time too long, etc. ) in the Fault Menu.

Possible Errors

List of errors:

Number Type of error

00 No faults

01 Fault in writing to EEPROM This fault defines transfer problems between the memory cartridge and the controller. If the fault occurs frequently, contact the after-sales service.

02 Fault in writing to the clock If the fault occurs frequently, contact the after-sales service.

04 Overload on transistor outputs Once a transistor output reaches a temperature of 170C, the group of 4 outputs to which it belongs is deactivated. To make this group of outputs operational, the cause of the over current (short-circuit, etc.) must first be deleted, and then the fault cleared from the FAULT menu.

50 Module firmware is damaged Reload the firmware on the module and the user application. If this problem persists, contact the after-sales service.



51 Watchdog overflow Warning or error according to the selection made in the configuration menu (module display) or in the configuration window (Zelio Soft 2 programming workshop). The cycle time in the module is too short compared with the application program execution time programmed in the controller. If the application requires a strict sampling of the module inputs/outputs, lengthen the cycle time in the module. To do this, configure the information either in the CONFIGURATION menu (module display) or in the configuration window (Zelio Soft 2 programming workshop). If the application does not require the cycle time, in CONFIGURATION select: No Action for the WATCHDOG.

52 The controller has executed an unknown operation. If the fault is permanent , reload the firmware on the module and the user application. If this problem persists, contact the after-sales service.

53 Link between module and bus extension faulty Check operation of the extension (connection, power supply, fault).

54 Link between module and input/output extension faulty Check operation of the extension (connection, power supply, fault).

58 A fault is present in the firmware (software specific to the controller) or on a part of the controller hardware. If the fault is permanent, reload the firmware on the module and the user program. If this problem persists, contact the after-sales service.

59 At the beginning of RUN on the module application: the application cannot switch to RUN as it is incompatible with the module physically connected to the supply. If this problem occurs, contact the after-sales service.

60 At the beginning of RUN on the module application: program incompatible with the bus extension physically connected to the supply. If this problem occurs, contact the after-sales service.

61 At the beginning of RUN on the module application: program incompatible with the Input/Output extension physically connected to the supply. If this problem occurs, contact the after-sales service.

62 Version (or build number) incompatibility when loading a program from the backup memory If this problem occurs, contact the after-sales service.

63 Hardware configuration incompatibility when loading a program from the backup memory If this problem occurs, contact the after-sales service.

How to check an application using the ZelioSoft2 programming workshop

At a Glance

The check command launches the program compilation, then the result of the compilation is displayed in the Compilation results window. Two types of check can be used for an application:

The first checks the consistency between LD or FBD diagrams,

The second checks the performance of the user application, i.e. the suitability of:

The memory usage,

The cycle times of the user application,

Memory capacities,

The execution speed of the module.



Diagram Consistency Check

If the option: Display compilation results in simulation mode and when loading is activated in the workshop preferences, the compilation is performed automatically in the following cases:

Consistency of FBDs This only concerns SFC network linking errors. FBD networks always behave consistently: Inconsistent linking is impossible, and the non-linking of an input sets it to a constant value that does not affect the execution of the function or makes it passive. See the on-line help for each function. Consistency of LDs The LD network can be simulated, loaded and executed on the module at any time. Hence it can be built and debugged progressively. However when wiring anomalies are detected (cable without termination, function Reset not connected, etc.) an eye symbol goes from blue to red in the upper panel of the edit window. Double click on the red eye to open a program consistency window which gives details on any detected anomalies. These warnings are always intended to draw the attention of the user to singular wiring instances, which may nevertheless be perfectly justified in certain applications. As a general rule, these warnings correspond to incomplete wiring, to the non-wiring of certain inputs (e.g.: Reset function ), to parameters left in their default value, or to certain odd Clock configurations (where the output stays ON permanently).

Switching from Edit mode to Simulation/Monitoring mode,

Transferring of the program to the module.

User Application Performance Check

This appears in the Compilation result window in the following cases:

These performance checks are useful in a simulator as they can be used to obtain the module that meets the requirements of the planned application, once the application is created and simulation-tested.

Activation of the Edit\Check the program command,

Switch from Edit mode to Simulation/Monitoring mode (if activated in the Workshop Preferences),

Transfer of the program to the module (if activated in the Workshop Preferences).

Note: When optional, the window is only displayed when the module capacities (memory space and execution speed) are too low in relation to the user program being checked.

Note: The compilation time for programs that use more than 128 FBDs or SFCs and numerous loops, may exceed several minutes. A rotating Schneider logo is displayed on the screen of the PC throughout the process.

User Application Memory Size Check

The available memory resources depend on the type of controller and operating mode selected for the firmware (LD mode or FBD mode). The program compiler calculates the volumes used in the different memory zones of the controller:

The parameters (FBD and LD function blocks): 2 bytes for each integer and 1 byte for the other types,

The parameters associated with the LDs: the number of bytes corresponding to the maximum number of LD lines, and maximum number of function descriptions that can be programmed for the selected module (independently from the ZeliosSoft2 programming workshop),



In the event of capacity overrun, the window is nonetheless displayed and the overrun zones are shown in red. The zones shown in blue alert the user to the fact that the size of the application memory zone

concerned is significantly near the maximum capacity of the selected modules corresponding

memory zone.

The bit data (block outputs): 1 bit per Discrete, or per SFC Token, or per Boolean (in FBD) or LD contact,

Other data (FBD and LD function block outputs): 2 bytes for each integer,

Program zone: the number of bytes corresponding to all function blocks displayed in FBD, and all functions that can be programmed for the selected module type (independently from the ZeliosSoft2 programming workshop).

User Application Estimated Duration Check

The compiler also calculates the estimated duration of the program by adding together the elementary cycle times of each function used. The user application is executed periodically, and its cycle time is defined in Program Configuration\Configuration tab\Adjust the module cycle time accessible by clicking the

icon in the toolbar (edit, simulation and monitoring mode).

This period corresponds to the minimum sampling period of the modules inputs (except for

the fast counter function) and the minimum period for modifying the output values. The application response time is therefore twice the duration of this period.

Not all automation applications need a blockage on overrun of the target application cycle time. Indeed, in some cases such a blockage is dangerous. The user can therefore choose to use a WATCHDOG which will generate an alarm or error, if the application is in RUN mode on the module, when the application cycle time, added to the duration of the processes specific to the operation of the module and any extensions, exceeds the duration of the selected period. The action of this WATCHDOG (activated by default) is defined in Program Configuration\Configuration tab\Adjust the module cycle time accessible by clicking the

icon in the toolbar (edit, simulation and monitoring mode). A WATCHDOG warning can be returned to an FBD program, enabling the user to activate a retrieval sequence in the application, by using the module status function.

To determine the duration of the program cycle time, programmers must:

To guarantee a constant program cycle time, you must also carry out appropriate tests on the controller to verify that alarm or error 51 does not appear.

Note: (please take into account that the compiler arranges FBD functions from inputs to outputs, cutting the loops as close as possible to the outputs and SFCs from each INIT STEP or RESET INIT, to the downstream steps. )

Note: all LD and FBD functions have a defined maximum cycle time, with one exception in FBD: the cycle time of the TIME PROG function, which can vary from 1 to 51 depending on the number of events used.

Take into account the estimated duration in the compilation results table,

Carefully read and apply the recommendations written in the online help file: Available

duration for the program.

Duration of Processes Specific to the Operation of the Module and any Extensions

In addition to the processing time for the function blocks contained in the application program,



there are a number of additional processes during an execution period which can be easily

defined (as long as fixed) and are taken into account in the calculation of each periods

available application execution time (compilation result). But there are others, which can be either occasional or hard to quantify or account for. Processes hard to quantify:

Episodic processes:

The WATCHDOG always has no effect for the period in which one of these processes takes place.

Synchronous periodic interruptions which take up an extra 1 ms for each 10 ms in a period (i.e. 1 ms for a period of 10 ms and 5 ms for a period of 50 ms). These interruptions are used to acquire microprocessor inputs,

Interruptions relating to the fast counter (HSPEED COUNT).

Clock management: switch between summer and winter time: 1.60ms,

Compensation for clock drift once per week, every Sunday at 01:00: 4.38 ms.

Note: If the application presents no danger for personnel or devices in the event of an

increase in the periods duration, simply set the WATCHDOG to inactive. Otherwise, you

must check the maximum cycle time.

Note: Measurements of analog input values on controllers supplied with an AC voltage (24

VAC and 100240 VAC) are performed every 20 ms. Consequently, if you choose a cycle

time of 10 ms, analog input acquisition for these types of controllers will take place every two cycles.

Note: Modifying parameters using the FBD DISPLAY or LD TEXT functions on the front panel of the controller increases the application cycle time by a variable time. The same applies for the other commands (PARAMETERS, etc.) carried out from the front panel. The WATCHDOG always has no effect in this module operating mode (Module status).

Note: The display of various data (text, data, hour, date) by active FBD DISPLAY functions or an active LD TEXT function, on the module LCD increases the application cycle time by a variable duration. This duration depends on the type of data to be displayed and, for the FBD, on the number of DISPLAYS simultaneously active (maximum: 32).

Note: In Monitoring mode, the cycle times are increased by the communication times between the PC and the controller. No guarantee can be made concerning the real cycle times during this operating mode. The WATCHDOG always has no effect in this module operating mode (Module status).

Maximum Application Cycle Time Check on the Module

Given the problems of accurately estimating the user application cycle time and those of certain processes specific to the operation of the module, whereby increasing the cycle time of the application can present a danger for personnel or devices, in order to guarantee the maximum cycle time of your program you must perform the relevant tests on the module to check that alarm 51 (WATCHDOG overrun set to Alarm in Program Configuration) does not appear.

How the module behaves in the event of power outage

Power Outage

A power outage causes the following behavior:

The application is blocked, the reading on the LCD is frozen, and buttons become inactive. The outputs calculated by the application are frozen in the status they were in prior to the detection of the power outage.

The links with the PC and any extensions are blocked:

The workshop displays the following message: the target peripheral is not reacting. Check the connection,

The outputs of all input/output extensions are deactivated,

The Modbus extension continues to emit normally 80 ms after the power outage that affacted the module,

After 80ms, The Modbus extension detects the module operation defect and sets its status word to Time_OUT_SPI, then loses its module-specific supply.

The module display is cleared, the rear-light switches off and all module outputs are deactivated.

The date and time increment during the power outage on modules fitted with a clock (battery supply).



Restart Following a Power Failure

The module checks all its extensions are operating normally, then returns the data stored during the power outage, and restarts the application execution with a specific initialization sequence for returning power. This sequence initializes all function inputs and outputs, except the outputs of the functions protected by a checked latching parameter. In this case, these outputs are not reset, and therefore conserve the value they had at the time of the power outage. To find out which function outputs are protected on power outage, consult the function description. Functions with parameters in LD mode:

Functions with parameters in FBD mode:

Special case of SFC components. On restart after a power outage, the positions the status tokens held in SFCs whose power was cut are:

Auxiliary relays,

Location of Zelio Soft 2 files

Description

Once the installation program is executed, all of the files needed to execute Zelio Soft 2 for Zelio Logic Modules are stored in a set of directories described below: Illustration:



By default, this software set is located in C:\Program files\Schneider Electric\Zelio Soft 2\. If the user proposes another installation directory, that is where the abovementioned software set will be located. The Zelio Soft 2 directory contains five sub-directories, containing respectively:

Zelio Soft 2: binary files of the Zelio Soft 2 workshop. This includes Zelio2.exe, the executable root, and a set of DLL files corresponding to each of the available tools. The files Lang_X.dll (where X is the language number) contain all character strings displayed by the workshop (menus, warning/error messages). The file Infos.env contains all the environment information that can be used to save the condition of the Zelio Soft HMI on closure of the workshop (choice of display options, window position, opening or closing of windows ) then restore it the next time it is opened. The file Z2special and Z2normal contains the specific fonts used by Zelio Soft 2. Mfc42.dll and Msvcrt.dll are Microsoft libraries.

Z2Ctlg: files and directories associated with the catalog, and therefore with the description of the Zelio Logic controllers, their performance and the associated extensions, as well as the resources and their settings. The catalog file is called Z2dc15_ctlg.tz2. Each file containing the catalog texts displayed in the workshop language by the HMI is called Z2TxtCts_X.tz2 where X represents the language number:

The associated bitmap files used to illustrate the Zelio Logic module category choices, are called SR2AB10-12.bmp, SR3B26J.bmp. Finally, there is a set of files used by Zelio Soft but with no connection to the catalog. These are files like Z2TxtCls_X.tm2 where X represents the language number. These files are used to display in a language the tooltips associated with the standard functions: the function name and names of the inputs and outputs.

X=0 corresponds to French,

X=1 to English,

X=2 to German,

X=3 to Spanish,

X=5 to Italian,

X=6 to Portuguese.

Z2Dc27: binary files of the Zelio Logic module software in each of the operating modes (LD and FBD) and for the various languages (French, English, German, Spanish, Italian, Portuguese).

Z2Help: files (Zelio2_X.chm where X is the language number) containing the on-line help manuals in each language.

readme: README type files specific to the current version of the product and in all languages.

Z2User: by default, after installation of Zelio Soft 2, all user program files (.zm2 extension) are stored here. However, the user can impose a specific storage route with the command "Save as" or by selecting a different "Work directory" using the "Preferences" menu. The user can move all .zm2 files to a directory of his/her choice.
