Protocol Specific

Modbus

Modbus is a communications protocol originally published by Modicon (now Schneider Electric) in 1979 for use with its programmable logic controllers (PLCs). Simple and robust, it has since become a de facto standard communication protocol, and it is now a commonly available means of connecting industrial electronic devices.

Functions

Tags

This function allows user to created named points. After points created, user can send it manually or set reply checkbox to automatic reply.

 

 

 

 

Creating Tag

In Modbus protocol tags are mostly used for Slaves to simulate specific data registers, although they can be used in Master to write data to slave registers or format received data from Slave devices.

There are two ways of creating tags:

1. Add button in the tag menu.

image-1643024563180.png

2. Left mouse button double click value in statistic tab.

 

Slave

If the simulation mode is Slave a modbus tag creation window should look like this and have these parameters.

image-1643025456556.png

 

Master

If the simulation mode is Master a modbus tag creation window should look like the one shown below and have these parameters.

In this case since this is the Master tag creation window it has two additional buttons that give the master the ability to write data to the Slave device. For the selected type he buttons are Write 5 and Write 15 correlating to the modbus types. 

In Master applications tags are mostly used to format data read from Slaves since data reading from devices is done using Jobs.

For types 1 and 2 the buttons will be Write 5 and Write 15. 

For types 3 and 4 the buttons will be Write 6 and Write 16

image-1643026840765.png

Jobs

Jobs are only available in Master simulations. What jobs are meant for is reading data from the Modbus slave device. They can send requests for big chunks of data in a single request. Then the data that slave responds with can be formatted using tags.

Job has these parameters:

image-1643027572918.png

Command

Commands are only  available in Master simulations. Commands are used to send data to Slave devices. They serve the same purpose as Write 5 and Write 6 buttons in tags.

Although, commands will send data to the Slave address configured in the Settings tab whereas tags will send the data to the Slave address configured in the tag configuration.

image-1643027975682.png

When using commands make sure to enter the desired Slave Address in the settings tab.

Setup

To setup an Modbus simulation it is fairly straightforward. 

1. Select Modbus and the mode.

image-1643102234120.png

There are three different Modbus modes: Modbus TCP, Modbus Serial RTU, Modbus Serial ASCII.

2. Select Serial Port settings according to your device specification. 

image-1643100262054.png

          2.1 If Modbus TCP is used then the IP address and Port will have to be selected.

          image-1643102340758.png

3. Select settings in the settings tab according to your device, preference and selected mode. 

image-1643102386002.png

4. Press the green START button and the simulation should start. If everything was done correctly The Vinci software should establish communication with the Modbus device which you can monitor in the console tab.

IEC 60870-5-101

Custom Commands

This function allows user to send commands to the slave device.

image-1643036278042.png

Tags

This function allows user to created named points. After points created user can send it manually or set reply checkbox to automatic reply.

There are two ways of creating tags:

  1. Create tag button.
  2. Double click a signal with the left mouse button in the statistic tab.

Main parameters:

Here is an example image of the tag window with the M_SP_TB_1 (30) type selected.  Each type has different options that can be configured when sending data. For example this type depicted in the picture below can send a value Off or On and it also is time-tagged. The user in this case can either select a specific time that they have in mind or just mark the PC checkbox and The Vinci software will automatically send the current PC time. As you can see the Value box in this example is greyed out that is because this tag is created on a master simulation, and this type doesn't support writing to slave.

image-1643099817811.png

Setup

To setup an IEC 60870-5-101 simulation it is fairly straightforward. 

1. Select IEC 60870-5-101 and the mode.

image-1643100190017.png

2. Select Serial Port settings according to your device specification.

image-1643100262054.png

3. Select settings in the settings tab according to your device and preference.

image-1643100334429.png

4. Press the green START button and the simulation should start. If everything was done correctly The Vinci software should establish communication with the IEC 60870-5-101 device which you can monitor in the console tab.

image-1643100408248.png

IEC 60870-5-103

IEC 60870-5-103 is a protocol for power system monitoring and controlling. Mostly used for communication between protection devices and devices of a control system in a substation (RTU) over fiber optics.

Clock synchronization

This function will send telegram Type-identification = 103 (C_CS_NA_1)

If "PC time" checkbox is checked, then the PC time will be sent. If it's not checked user can set time manually.

General Command

This function allows user to send command to slave device.

Tags

This function allows user to created named points. After points created user can send it manually or set reply checkbox to automatic reply.

There are two ways of creating tags:

  1. Create tag button.
  2. Double click a signal with the left mouse button in the statistic tab.

Main parameters:

Here is an example image of the tag window with the TimeTaggedMessage(1) type selected.  Each type has different options that can be configured when sending data. For example this type depicted in the picture below can send a value Off or On and it also is time-tagged. The user in this case can either select a specific time that they have in mind or just mark the PC checkbox and The Vinci software will automatically send the current PC time. As you can see the Value box in this example is greyed out that is because this tag is created on a master simulation, and this type doesn't support writing to slave.

Setup

To setup an IEC 60870-5-103 simulation it is fairly straightforward. 

1. Select IEC 60870-5-103 and the mode.

2. Select Serial Port settings according to your device specification.

image-1643100262054.png

3. Select settings in the settings tab according to your device and preference.

4. Press the green START button and the simulation should start. If everything was done correctly The Vinci software should establish communication with the IEC 60870-5-103 device which you can monitor in the console tab.

IEC 60870-5-104

IEC 60870-5-104  is a protocol for power system monitoring and controlling. Mostly used to communication between substations and control centers over Ethernet (Fiber optics, 2/3/4G, ...).IEC 60870-5-104 protocol is an extension of IEC 60870-5-101 protocol with the changes in transport, network, link and physical layer services to suit the complete network access.
