OPC Live Data access Problem
I am using 800xA Rev 5.1 rollup Rev A. Whenever I am downloading a controller the OPC connection for Data access is going down for that particular controller.I checked in OPC server log file and it is showing "Exception when extracting FSD file C12_L2.ctdbXml. HRESULT=0x8abb45c5 (ExtractCompilationFile(...)). Failed to extract file from PPA via FSD. Name: C12_L2.ctdXml" where C12_L2 is the controller I have just downloaded.This problem is happening quite often and everytime I need to restart the connectivity server to get rid of this problem.
If anybody having any solution ,please share with me.
Check of there are any Number of missing physical controller and if it was connected in the OPC Server panel. If there are any such controllers disconnect them or bring them online and check.
Its also recommended to disable the Ethernet Backup Interface on controllers if they are not Redundant configured
