You may need to identify the protocols used in a project without starting that project (e.g. because you do not have the appropriate version of PcVue). You can do so by checking the configuration and system files as follows:

• Open the file …\Pcvue\USR\project\C\COMM.DAT in a text editor.

Example of contents of a COMM.DAT file:

VERSION,1,0

BOARD,0,1,5,0,0,53248,816,,,0,0,””

NETWORK,0,0,r1,220,FACTOR ACCESS

0,0,0,NO,0,0,0,5,0,1,0,0,,,0#0#0#0#0,,,0,0,””,0,0,3

EQT,0,0,0,e1,1,DAU_MODBUS,16,0,0,0,0,5,0,1,0,,0,1,0#0#0#0#0,0,,,0,0,””

FRAME,0,0,0,0,t,2,250,125,R,0,Mot E :,65,0,0,1,0,0,0,0,1,1,,,0,0,””

• The name and version number of the protocol appear in the Network line such as:

NETWORK,0,0,r1,220,FACTOR ACCESS

• In the example, the protocol number is ‘220’. Close the file COMM.DAT.
• Open the file …\Pcvue\Bin\PROTOC.DAT in a text editor.
  Caution: Since PcVue version 16, protoc.dat has been removed. It is now possible to find protocols by searching into CimWayProtocols.xml in Bin folder of the PcVue software.

Example of the contents of a PROTOC.DAT file:

PROTOCOL,226,10,CWSBUS.DLL,SCOM32L1.DLL

Do not modify the file PROTOC.DAT.

• Check the .DLL files linked to the protocol number. (In the example, the file name for protocol ‘220’ is ‘CWTRMMS.DLL’; but this protocol needs another .DLL file to be loaded: ‘TRMMSI.DLL’, provided by manufacturer.)

In the file COMM.DAT, the files named ‘CWxxx’ are PcVue’s .DLL files. The others are manufacturers’ DLL files.

The COMM.DAT file is created when you first configure a protocol.

More about the PROTOC.DAT file

In the 3rd field of the PROTOC.DAT file, you will see these values:

The C++ API interface is easier to use and new protocols are developed with it.

If you need to know which version of protocol DLL is provided with your installed version of PcVue:

1. In Windows Explorer, open the Supervisor’s ‘…\Pcvue\Bin\’ folder.
2. Right-click on the .DLL file for the protocol (e.g. CWTRSMMS.DLL) to open its Properties dialog, then open the Version tab.
3. In the list of element names, click on ‘ProtocolVersion’ to display the version number of the .DLL in the right-hand pane.

To check for compatibility, you can also display the version of the CIMWAY software under which this DLL was compiled:

1. In the list of element names, click on ‘Product Version’ to display the version number of CIMWAY in the right-hand pane.
2. Click on Cancel to close the dialog.
