1 Introduction to Microelettrica Scientifica and MSCom

1.1 Microelettrica Scientifica Microelettrica Scientifica manufactures high-performance, reliable electric components and systems. Its name can

be found in all the most progressive sectors of industry.

Microelettrica Scientifica, particularly dedicated to research and innovation, has always played an active part in the

great technological changes of our time.

Founded in 1953, Microelettrica Scientifica has developed a wide range of products, divided into the following main

lines:

Electronic Relays for Transmission, Distribution and Machinery Protection

Series A: electronic analogic;

Series M: digital microprocessor.

Contactors for railway applications: these contactors have been expressly designed for application on

vehicles for electric traction. They are available as standard for applications from 1000 to 4000 V DC and can

also be used in AC circuits.

Contactors for industrial applications: these contactors find their specific application in the heavy industry,

where high performances and heavy duty are required as in control of cranes, rolling mills, mining equipment

and so on.

Resistors for industrial applications: due to their considerable electrical and mechanical characteristics, and

because of their modular construction, these types of resistors can be used in different applications: starting,

braking and slip control resistors, load resistors, star point earthing resistors, filter resistors, connection and

discharge resistors and current limiting resistors.

Resistors for railway applications: traction resistors have been supplied to railways and underground

systems for various application, like as braking and filter, and they have been designed and manufactured to

operate under the most severe conditions, including extreme environmental temperatures, shocks and

continuous vibration, polluted atmospheres, rain, snow, ice…

1.2 MSCom MSCom is a Windows-based communication program developed by Microelettrica Scientifica.

Microelettrica Scientifica is now delivering two versions of MSCom :

The Lite version (MSCom Lite) is totally free and it’s delivered with any Microelettrica Scientifica

microprocessor relay. It implements the ability to communicate with only one relay at the same time, the saving

of all relay data on the disk, the print of the data, but it doesn’t implement the ability to communicate via

modem, the graphical representation of the oscillographic data…

The Professional version (MSCom Pro) is a stand-alone product implementing the ability to communicate with

more then one relay at the same time (up to 5 relays), the saving of all data on the disk, the configuration of the


MSCom Rev. 4

Pag 5 di 46


print out, the TCP/IP connection to the remote substations, a completely configurable polling and more

others…

The Professional version is a program to purchase separately.

MSCom program is suitable to read / modify settings and real measurements and all other stored values in any

Microelettrica Scientifica microprocessor relays.

MSCom is able to support all relays at the moment delivered by Microelettrica Scientifica.

MSCom Pro provides some additional features:

Connection up to 5 five devices at the same time.

Remote access via modem and phone line.

Printing: you can print the active relay data.

Saving: you can save in a file the active relay data, the opened file or the relays data available on the network

Measurements Polling: One or more variables per relay can be periodically read and displayed to the user. All

the data can also be recorded on the P.C.'s hard disk or directly sent to a printer.

Last Trips Polling: MSCom monitors the status of the relays trip counters. A new file containing the relay data at

the last trip is automatically generated whenever a trip counter is incremented by the relay.

MSGraphics : Graphical representation of the oscillographic data

Synchronization : the relays internal clocks can be synchronized through a periodic signal sent out automatically

by MSCom

3 Hardware and Software Requirements

3.1 Hardware Requirements PC Hardware Requirements

− PC with Pentium processor.

− At least 32 megabytes RAM.

− At least 100 megabytes free hard disk space.

− Colour monitor capable of VGA resolution ( al least 640x480 resolution with 256 colour)

− Keyboard and mouse.

Serial interface requirements The interface used for connection is RS-485 (half-duplex), which allows to connect in parallel up to 31 units.

The communication bus can be long up to and over 1000m if shielded twisted pairs of cable are used for

connection. Using a simple twisted pair the recommended length is reduced to 500 m. Using a fiber optic

transmission, up to 200 units can be connected on the same bus with distance up to 3 Km between units (glass

fibre optic).

For connection refer to attached diagram SCE1309.

An RS232/485 adapter is needed to use one of the serial ports available on the personal computer for the relay

management.

Microelettrica Scientifica's 232/485 converter automatically recognizes the data flow so no configuration is needed.


MSCom Rev. 4

Pag 7 di 46


The use of a P.C. serial port fitted with a UART type 16550 is recommended; normally high speed serial ports

(baud rate over 9600bps) use that component.

If more than 2 serial ports are available on the P.C., please note that normally ports COM1 and COM3 share the

same interrupt (likewise for COM2 and COM4): therefore if for instance the mouse is connected to COM1, the relay

management bus shall not be connected to COM3 but to COM2 or COM4 only.

If a 485 interface card has to be installed in the computer, make sure it is configured so that transmission is

enabled by the RTS signal and that it does not clash with existing communication ports.

3.2 Software Requirements 3.2 Software Requirements

Microsoft Windows operating system: Windows 9x, ME, NT4 SP3, 2000.

4.2 Basics

4.2 Basics If you have just started MSCom you are probably seeing this screen :

(to identify the graphical items please refer to “Getting Started”)

As a MSCom user you will make constant use of the Relay Manager Window, that makes available the most

common commands that are on the pop-up menu; their presence in a single window improves the user-

friendliness.

In the list boxes you can see the list of the relays available on the network , the list of the relays available in the

opened file and the relays you already have opened from the file or from the network.

MSCom has the possibility to open more than one relay at the same time. The last relay you have selected is the

Active Relay. To change the active relay you can change the selected line in one of the list boxes or you can point

on one of the relay windows and click on the mouse left button.

The Tool Bar buttons and the Menu Bar always refer to the currently active relay.

The MSCom status and other info about the active relay and the communication parameters are displayed in the

Status Bar


MSCom Rev. 4

Pag 10 di 46


MSCom program can be in 2 different status:

Read Only Read / Write

In the Read Only Status you can open all windows ( Actual Measurements Window , Maximum values Window ,

Measurements at the last trip Window, Trips Number Window, Status Window, Settings Window , F->Relay

Window) but when you try to send data or commands to the relay, MSCom will ask you to insert the password to

enable the Read / Write status.

In the Read / Write Status all the windows functions are directly available.

4.3 File Save Using MSCom Pro you can save in a file the active relay data, the opened file or the relays data available on the

network.

The save procedure is accomplished through the use of the menu options File | Save Active Relay, File | Save

Relays on network list, File | Save

In any case the data are saved in files having a ".cir" extension. The file format is compatible with the file saved

with V-PRO II 2.1.

4.4 Printing MSCom Pro allows you to print the active relay data. The print procedure is accomplished through the use of the

menu option File | Print. Before selecting menu option File | Print, select the Active Relay you want to print by

clicking it with the mouse left button in the Connected/Opened Relays list box in the Relay Manager Window.

MSCom print configuration enables you to decide what you like to print before you send it to the printer.

5. General Overview and Features

MSCom consists of a number of modules which work together to help you to improve the plant control capability.

5.1 Relay Manager Window

The Relay Manager Window is displayed when MSCOM starts and is used to:

Find on the network all the available relays.

Open a file.

Open / Close any relay on the network / on the file.

Connect / Disconnect the active relay.

Relay Manager Window displays all info you need about which relays are in the plant, which relays you have

already opened from the file or connected in the network.

The Scan Network button fills the list box of the Relays available on the network with the list of the relays available

in the network. After you start the procedure, the button changes in Stop Scan and if you click on it you stop the

scan operation.

When the Scan Network procedure is running, MSCom calls the Modbus nodes, trying to receive an answer to

identify the relay model at the specified node. The node number that is called up is reported in the Relay Manager

Status. If it identifies a relay in the network, it adds a new line in the list box of the Relays Available on the

Network.

The Scan Network procedure doesn’t affect the other MSCom procedures, so you can see the active

Measurements window of the active relay updated when the Scan Network is running.

The Connect New Relay button connects a relay available on the network.

• Source1 and Source 2: these radio button group boxes allow to select the curves from which you calculate

the new curve.

• Operation: this combo box allows to select the mathematical operator.

• The Calculate button draws the new curve and closes the window.

Warning: the points of both curves involved in the mathematical transformation must have the same x

coordinates.

“General Options” window allows you to set the number of points for graphics and to display the curves in 3D

(this option is very useful when the curves are superimposed)

5.2.7.1 Polling

The Polling functions (available only in the MSCom full version) let the user's P.C. monitor more than one relay at

the same time.

One or more variables per relay can be periodically read and displayed to the user. All data can also be recorded

on the P.C.'s hard disk or directly sent to a printer.

Two main polling functions are available :

Measurements Polling: displays/records Actual Measurements and relay Status variables.

Last Trips Polling: monitors the status of the relays trip counters. A new file containing the relay data at the

last trip is automatically generated whenever a trip counter is incremented by the relay.


MSCom Rev. 4

Pag 29 di 46


5.2.7.1.1 Measurements Polling

Selecting the Polling | Measurements Polling menu, MSCom displays the Measurements Polling Management

dialog .

The Data Output frame allows you to configure the required output device. Clicking the Printer radio button,

MSCom prints directly the data during the polling. Otherwise, clicking the Hard Disk radio button, MSCom

stores in an ASCII file the polling data. You must select Printer or Hard Disk before starting the polling.

The Start button starts the polling procedure and clears the list box showing the polling data.

The Stop button stops the polling procedure without terminating it. You can restart the polling clicking this

button again (which is changed in Continue button)

The End button terminates the polling procedure.

The Format File frame displays the file path used by the Polling procedure to find the Polling Data.

The Output File frame displays the file path used by the Polling procedure to create the output file if the Hard

Disk radio button in the Data Output frame is selected.

Checking the Data Auto Scroll box, the list box is continuously updated to show the last polling cycle data.

Disabling the Data Auto Scroll you are able to change the list box scroll bar position to examine the data

received in the past.

The Polling Real Time is the measured time between two Polling cycles. (i.e your required polling time is 0.4 s

but the achieved Polling Real Time is 0.75 s because you have specified in the polling format file a (too) long

data list to receive from the relays)


MSCom Rev. 4

Pag 30 di 46


The Configuration button displays the Polling Data Config dialog which allows to modify the polling

configuration.

5.2.7.1.2 Measurements Polling Config

The Measurements Polling Config dialog is displayed by the Configuration button in the Measurements Polling

Management dialog.

This dialog allows to modify the Format Files. The Format file is an ASCII file that defines the polling data

output format.

The Header list box and the Data Lines list box show the 2 different parts of the format file contents. The first is

printed or saved on the disk only when you start the polling or restart after you have stopped it. The second

contains the definition of the data which are polled at each cycle. You can add in these parts whatever you want

to make the polling results clearer. The generic data format is:

[Node#-Variable name]

where # is the Relay Node number (in the Modbus network)

Variable name is one of the strings in Available variables list box

The separator between the Node definition and the variable name must be “-“. Here is an example:

[Node1-Ia] A [Node1-Ib] A


MSCom Rev. 4

Pag 31 di 46


You can add the time stamping writing [TIMER ].

Example :

[TIMER ] [Node1-Ia] A [Node1-Ib] A

You can write the data definition manually or you can automatically insert the node and variable name selecting

the required variable in the Available variable list box, the node number in the Node selected frame and click the

Add button in the Available variable frame.

If you are working with the relays on line you can select a node with the Node Selected frame and click the

“Show var.” button: MSCom will show the Relay model and the available variables. Otherwise you can select

directly the Relay Model and MSCom will fill the Available Variables list box with the names of the variables

available in the Actual Measurements and in the Status Window.

The format file path is showed in the Format File frame.

The Open button allows you to load another format file. The Save button stores on the disk the format file which

is showed in the Header and in Data Lines list boxes.

Anyway, when you close the Polling Data Config Window clicking the OK button, MSCom will automatically

save the format file.

The Output File frame shows the file path for the polling data disk output .The Modify button allows you to

change this path. The output file is segmented in daily portions: data are never deleted, but added at the end of

each file.

5.2.7.1.3 Last Trips Polling

The Last Trips Polling option allows to control trip counter status.

Selecting the Polling | Last Trips Polling menu, MSCom displays the Last Trips Polling Management dialog.

This dialog is very similar to the Measurements Polling Management dialog of the Measurements Polling, the

only difference is the Configuration button that shows the Last Trips Polling Config Dialog.


MSCom Rev. 4

Pag 32 di 46


Here below an example of the Last Trips Polling Management dialog.


MSCom Rev. 4

Pag 33 di 46


5.2.7.1.4 Last Trips Polling Config

The Last Trips Polling Config dialog box is displayed by the Configuration button in the Last Trips Polling

Management dialog.

This dialog allows you to modify the Format Files of last trip (with extension .frp).

The format file is an ASCII file and contains general information, such as selected relays, scan time, compact

text status, etc.

The Header list box is a part of the format file and contains what is printed or saved on the disk only when you

start the last trip polling or restart after you have stopped it.

There are also 2 list boxes: Relay Available and Relay Selected.

The first one displays a list of relays available on the Network (if you haven't done scan network yet, no relay

will be displayed and a message will report it), while the second one displays a list of Relays that will be polled.

The Add button adds the selected relay to the Relay Selected List.

The Remove button removes the selected relay from the Relay Selected List.

The Add All button adds all the relays to the Relay Selected List.

The Remove All button removes all the relays from the Relay Selected List.

The 'Format File' group shows the format file name and allows to Open and Save a new format file.


MSCom Rev. 4

Pag 34 di 46


The 'Output File' group does the same things with the output file name, but only the Save button is available in

this case.

The Check Node group allows the user to check whether or not a relay is present at a given node address. To

use this function, select the node number and click on the Check button. If a relay exists, it will be added to the

Relay Selected list.

The ScanTime group sets the Trip Counter polling time.

The Add Simulation Relays button adds all the available relays at node 0 to the 'Relay available' list; this

makes the function executable in simulation mode.

The Compact text button lets you compress the output text. There are three modes available:

• 'Compact text OFF': in this mode no output message is deleted.

• 'Compact text ON': in this mode all the groups of messages not containing a trip message are deleted.

• 'Compact MAX': in this mode only trip messages are displayed.

5.2.7.2 Network Synchronization

The protective relays clocks synchronization is performed by a broadcasting message (a message to node 0).

The Network Sync | Tool menu option displays the Network Synchronization Config dialog window.

Inside this dialog you can specify the synchronization messages frequency

To start the automatic synchronization select a synchronization time and push the “START Auto Synchronization”

button. A warning message will ask you to set correctly the TSync settings inside each protective relays connected

in the network.

Pushing the “Cancel” button inside the message box you can stop the procedure and set conveniently the TSync

values.


MSCom Rev. 4

Pag 35 di 46


Pushing the “Ok” button inside the message box, if you inserted a correct value for the synchronization time, the

message box “Synchronization timer started.” appears and the Automatic Synchronization procedure starts.

On the top of the window a countdown counter starts: MSCom calculated the time before the next synchronization

time and used this value to set the initial point of the counter; now you can close the window. When the countdown

counter will be zero the broadcasting synchronization message will be sent out and a graphical confirmation

message (“Sending sync..”) will be showed on the screen for a couple of seconds. To stop the automatic

synchronization procedure, you have to push the “STOP Auto Synchronization” button.

When we talk about the Synchronization we mean that we set all the relays clocks at the same date and time.

Please refer to the Microelettrica Scientifica protective relays operation manual for more details about the TSyn

setting meaning and the Synchronization relays feature. Note: During the synchronization procedure we send:

- Date and time at the Modbus address 5120 (4 words)

- Latency Time at the Modbus address 5470.

- Synchronization command (we write the value 9 at the Modbus address 8000).

Latency time The synchronization message is a write Modbus message: it consists of 11 bytes. With a transmission baud rate of

9600 bit/s, the message is received by the relays after 11 milliseconds.

Since the required precision is 10 ms, we must take care of the transmission delay that we call “Latency time”

At the relays database we added a setting at the Modbus address 5470 to save the “Latency time” value.

When the relay receives the synchronization message it uses the value stored at the Modbus address 5470 to

recover the time lost during the transmission.

Latency time default = (1 / {Baud rate default }) * 10 * 11 * 1000

Obviously the Modbus master must update the Latency time in the Modbus slaves if the baud rate is changed.

This task is performed automatically by MSCom.

5.2.7.3 Remote Access

This menu option allows you to connect remote relays via 2 modems and a phone line.

After you selected the Tool / Remote Access menu, you are presented with a warning dialog:

This dialog allows you to change the active serial port: if you select “Yes” MSCom displays the

Communication Parameters Dialog (please refer to 5.2.8.4).


MSCom Rev. 4

MSCom tries to initialize the modem reading the “Modem.ini” file and executing the AT commands listed (please

feel free to modify the modem.ini file saved in the MSCom directory to fulfill your special needs). If the initialization

procedure fails an error message will be displayed.

NOTE : to disable the menu option “Remote Access” and return to the normal functioning of serial communication,

select the option Tool / Close Remote Access .

5.5 New Tools

New functions, to improve network control, will be available in the next version of MSCom Professional.

These new functions will be:

TCP Connection

Windows in Main Table

Actually these tools are in pre-release: the functions are active (appear in the menu and are selectable), but only as

a demonstration.

Here below there is a short description of these tools operation.

5.5.1 TCP/IP connection

This feature allows to connect two PCs through the TCP/IP protocol and monitor the relays connected to the

remote PC serial port; the TCP/IP connection physical medium can be a LAN , a phone line to a modem on the

other PC or a phone line to an internet service provider.

The remote PC must run MSCom but the remote user can use his own copy of the program. Possible connection procedure and software requirements:

Through a LAN: Window95 or Windows 98.

Through remote access (i.e.: via modem): Windows 98 or Windows 95.

5.5.2 Windows in Main Table The “Windows in Main Table” menu option displays a window with an “old fashion” data browser: the data are

displayed in a grid. Data coming from more than one window and from different relays can be displayed in the

same data grid.

This menu is activated only when at least one relay is opened or connected and at least one window is on the

screen. Selecting “Windows in Main Table” the data available in the opened windows of the Active Relays will be

inserted in the “Main Table “ Window. The “Main Table “ Window doesn’t affect the performances of the serial communication. The data are required to

the opened relay windows without asking more data to the relay through the serial communication.

The variables showed in the “Main Table” window are updated only if the related relay windows are opened.

Some useful advices to use the “Main table”:

To select a row, use the arrow keys on the keyboard to change the selected row or use the mouse and click on

the row you want to select.

To select more than one row, using the mouse, click and drag the mouse cursor, using the arrow keys on the keyboard, push the “SHIFT ” button.

To delete one or more rows, select the rows you want to delete and push the “Canc” button; a confirmation

message will appear.

The “Main Table” window is a stand alone program interfaced with MSCom. If The “Main Table” window is

overlapped by the MSCom standard windows, use the keyboard keys ALT and TAB to switch to the “Main

Table” application and to put it in foreground.

The “Main Table” window is useful if you want to monitor the behavior of some variables belonging to different

windows or to different relays. This feature is also nice if you want to print out only some variables in the order you

prefer.

5.5.3 Relay Demo

The menu option Relay | Open Demo Relay allows you to open a relay in demo mode (off line status)

Note: this option is active only if there is no Active Relay.

You are presented with the Demo Relay dialog which allows you to select the node number and the relay model.

The Ok button allows you to create the relay, after this all MSCom options, for Off Line status, will be available.

The Cancel button allows you to delate the operation.
