1 TaskTechnological task description/overview

This application describes the configuration of technology block DEMO_ANALOG(FB640) and the corresponding block icon (faceplate type) with faceplate. It servesfor displaying an analog signal. It can be used to display signals of analog entrycards.The signal to be monitored can:· be of type “WORD” or “REAL”,· be monitored for limit values,· trigger alarms or messages if any upper or lower limits are violated,· be simulated.

Note Before using the block in your own projects, check the proper functioning of theblock and adjust it to your individual requirements where necessary. The blockdescribed in this application is only intended as a template for creating your ownblocks.

3.3 Control and status signals

3.3.1 Processing of switching commands in the controller

The WinCC “OPdwCmd” control tag of a block is used to transmit commands fromWinCC to the PLC. The PLC block analyses the control command, executes thedesired action and then initiates a reset of all pending control commands. For thispurpose, the value of the control parameter is set to “0”.

· “IN_INT”The input is processed for the analog value display of an analog input modulein the 4-20 mA measuring range.

3.3.6 Enabling/disabling the simulation

The “Simulation ON” mode enables the simulation of the analog signal. Thisfunction is important, for example, if automatic functions shall be tested alreadyduring the configuration phase, although a process interface does not yet exist.Without simulating the feedbacks, many automatic functions (e.g., step sequences)cannot be successfully executed since the feedbacks are frequently requested instep enabling conditions or cause errors.

3.3.7 Resetting error

The following situations cause the block to go to the “Error” state and the “QOUT”output to take on the value of the “LO_LIM” lower limit:· Interlock (“LOCK” = 1)· External error (“ERR_EXT” = 1)· Wire break (“QERR_WIRE” = 1)

The following situation causes the block to go to the “Error” state and the “QOUT”output to take on the value of the “HI_LIM” upper limit:· Overrun (“QERR_OVERRUN” = 1)

If there is an error at the block (QERR = 1), it can be reset using the “L_RESET”input or by the “OPdwCmd” operator. This error status can only be reset if there areno other errors pending.

3.4 Block icon and faceplate

This example uses WinCC faceplate types. These faceplates are available forWinCC V7 or a later version and offer the advantage of central changeability.Consequently, it is no longer necessary to edit all process pictures when the blockicon has been changed. If the faceplate types are not available, you can alsoconfigure WinCC user objects.

Layout of the block icon and the associated faceplateTable 3-8

Block icon Faceplate

The technology faceplate provides the following functionality:1. Displayed operating states

– Display of the analog value– Value monitoring by means of a trend curve– Simulation

2. Displayed errors:– Interlock– External error– General error– “wire break” (only “iMode=0”)– “overrun” (only “iMode=0”)– “low range” (only “iMode=0”)– “high range” (only “iMode=0”)

The various states of the analog value are transferred to WinCC via the “QdwState”parameter – [bit 8.9, 18, 24 and 25]. The display of the block icon is defined in theWinCC “DEMO_ANALOG_ICON_Define.pdl” picture file.

how to integrate the “DEMO_ANALOG” block into an empty or an existing project.This example uses the unconnected STEP 7 block, the WinCC block icon(faceplate type) and the WinCC faceplate, which is embedded in a static picturewindow.The “Example blocks for WinCC and STEP 7” document describes how toconfigure a dynamic call of the WinCC faceplates.

4.1 Configuring the STEP 7 block

First you create a new STEP 7 project with “S7 15xx” controller and PC station(WinCC application), or open an existing project.

4.2 Configuring the WinCC faceplateTable 4-2

Action Description

4. Copying files

First copy all files from the delivered “WINCC_GRAPHICS/DEMO_ANALOG”directory into directory: “GraCS” and all files from the “WINCC_SCRIPTS”directory to the “library” directory of the WinCC project.

5. Creating a connection

After you have created a new project, you create a newSIMATIC S7-1200, S7-1500 channel in the tag management.

7. Configuring the start-up parametersOpen the “WinCC Project” from the “SIMATIC Manager”. Open theProperties of the WinCC station and select the “Startup” tab.

Enable the following “Runtimes”:

· Global Script Runtime· Alarm Logging Runtime· Tag Logging Runtime· Graphics Runtime

8. Registering the scriptsBefore you can use the provided scripts, they need to be registered first.

· Open the Global Script C Editor· Click on the “Generate headers” button

The previously copied scripts are now available for your project.9. Creating a start-up screen

· Create an empty WinCC picture, name it “Start.pdl” and define thispicture as start-up screen.

· Open the “Start.pdl” picture in the Graphics Designer.10. Inserting objects

· Create an object of the “Faceplate instance” type. Select the“DEMO_ANALOG_ICON.FPT” file.

· Create an object of the “Picture window” type.

11. Configuring the properties of the faceplate instance objectDefine the following parameters in the Properties dialog box of the faceplateinstance object:· Others > Scaling mode = “1:1”

Define the following tag assignments in the Properties dialog box of thefaceplate instance object:· User-defined2 > QdwState = “<tag prefix > QdwState” 1)

· User-defined2 > QOUT = “<tag prefix>QOUT” 1)

· User-defined2 > szUnit = “<tag prefix>QOUT” 1)

Configure the following direct connection for “mouse click”:· Source: Constant = “1”· Objective: Object in picture = “Picture window1 > Display”Figure 4-1

1) The tag prefix consists of program name, CFC chart and block name,followed by a dot.

· Others > Display = “No”· Others > Moveable = “Yes”· Others > Frame = “Yes”· Others > Title = “Yes”· Others > Adjust window = “Yes”

1) Same tag prefix as in step 13. When calling up the message window, thisprefix is also entered into the “MsgFilterSQL” property of the alarm control viascript. This ensures that only messages of the relevant block will bedisplayed.
