Hello,
in my project I keep getting the follwing error message:
PVSS00opc (1), 2015.12.02 16:01:29.787, SYS, SEVERE, 54, Unexpected state, OPCGroup CMD OPCWriteList::write: WriteThread did not terminate within timeout: Possible Server deadlock
The error message occurres after a download of the plc.
In the OPC group "CMD" are only items with direction "Out (individual)".
The error message seems quite clear and I guess the connection between the OPC server and the plc has not yet been restored, but the "write" should only be triggered by a value change of items in another OPC group (Direction "In"). Therefore the connection must have been restored but maybe not for this group?
Is there something I could do to analyze or avoid the error?
Thanks in advance
Dennis
