s7 driver pollig issue for redundant system.

[chm0527]

Hello. It's first time posting Question on the board.

There is a redundant system using S7 Driver.
Usually Primary is active and Seconday is deactive and data from S7 Driver are been polling and been changing.

But, When Secondary is active and Primary is deactive, Data from S7 Driver stopped.
At a Secondary Server, S7 Driver's connections seems to be disconnected.

This system is being used for over 1year.
In the beginning I developed and tested this system, S7 Drvier's status is okay. (Even When Seconday is active, Data from S7 Driver is moving)
So I think, Project file got a trouble or was collapsed by operationg or importing / deleting tags or anyting else.
In system mangement S7 Driver, Device connection but polling is abnormal.


could you let me know what I check it and how I can fix it.
I attach log image file from this test system.


thanks.

Hello,

Please check the corresponding _DriverCommon_2.PM DPE and set it to TRUE if it is not set already.

Hallo,

Please check also the settings on _2 datapoints of _S7Conn Datapoint type.
Maybe the connections are not active on the second host.

best regards
Andreas
