Summary:

This article explains how to declare a communication protocol so that a project can use it.
Details:

You can define a communication protocol in a project using the dialog Network Board and Protocol Selection from the menu Configure.Communication.Equipment.Select Communication Objects, CREATE. To connect other PLCs (e.g. SIEMENS S7-IP), you must add a protocol to the existing configuration. When the configuration dialog is next opened, it shows Network Board as invalid. 

In the standard configuration, you can add a SCHNEIDER protocol but not choose for example the SIEMENS manufacturer.

To avoid this problem, you must edit the communication configuration file, COMM.DAT, which is created when you first configure a protocol.

1. Open the project’s C folder and open the configuration file COMM.DAT in a text editor. (Note: from “NETWORK” to “1,0,3” is all one line of code.)
VERSION,1,0
BOARD,0,1,1,0,0,0,0,,,0,0,””
NETWORK,0,0,Network1,232,COM1,9600,8,EVEN,1,0,0,0,800,1,0,0,,,0#0#0#0#0,,,0,0,””,1,0,3
EQT,0,0,0,PLC1,0,BROADCAST,0,0,0,0,0,0,800,1,0,,0,,0#0#0#0#0,0,,,0,0,””

2. In the BOARD line, the fourth field identifies the manufacturer: (For example it’s 13 for Schneider)
BOARD, 0, 1, 13, 0, 0, 0, 0,, 0, 0,” “

3. Replace that value with 1 (for Multi-protocol)
BOARD, 0, 1, 1, 0, 0, 0, 0,

The configuration dialog now gives access to all the protocols in the Protocol column

Warn

You must stop PcVue before you modify the COMM.DAT file.

Note

Always save your project before you change it.

Note

Always select Multi-protocol when you start to develop a project.
