Unexpected state S7HWService::start

Post by eMichx »

Hello,

I have an severe error reported on my standby server.
"Unexpected State; S7HWService::start Error on internal DP for connection "
This error is repeated for each PLC
Note : this error is not displayed on the active server.

When the passive server becomes active, there's no more general request sent by the S7 driver as we have checked it on the first active server.
The configuration (internal DP) are equal. EV process seems to be correctly activited on the rigth server (System Overview)

I have modify the config file to run the server in standalone mode, and it's working.

When I add debug flags on the S7 driver, I have just the calling function "addDpPa".

functions "processData2DP", "addItemReal" are just called on the first active server.

I would like to add I'm using WinCC OA 3.12. I have tested with and without patches (P22)

regards
Emmanuel

Hello,

I have created manually __2 internal DataPoints (_S7_Conn type) and it seems that
it's work better (general resquests are sent, independantly of the active server)
Why these points have not been created automatically?

regards
Emmanuel
