IEC 104: IEC server communication with redundant server with IEC client configuration

[paramesh1985]

Hi,

Requirement:

WINCC OA Single IEC-104 server communication with redundant WINCCOA servers configured as IEC clients.
Description:

We are not using PLC for testing; configured scada server as a IEC-104 server and IEC-104 client.
The configuration works fine with one scada server. when we have tried to communicate with the redundant scada servers the log viewer throws error.
We could not able to use different port number for redundant scada servers.

Query:
Is it possible to confgiure communication as per mentioned requirement?
Please suggest what are the possiblities.

We managed to solve the problem with IEC-104 server (TCP Server) configured with two IEC connections configured in connection panel for each redundant servers. while port number is defined in config file.
On Redundant server side serving as IEC-104 client (TCP Client) is configured with same port number for each connection in IEC connection panel.
