800xA with advant master: AC450 controller object is unable to retrieve system status
We have MP200 controller with System 800xA 5.0 SP2 installed. AC110 controllers are installed for voltage regulator and turbine governor.
MasterPiece 200 (MP200) controllers interfaces with system 800xA via PU410.
Our task is to replace MP200 with AC450 (PM511) and AC110 with AC160 (PM665) and upgrade 800xA 5.0 to 5.1.
We have installed 800xA 5.1 with all required packages.
RTA board from control structure shows healthy status and services are all healthy.
It is possible to upload through MB300 uploader and all objects are appearing in the control structure but the values are not updating online (Comes with a red cross mark in system status viewer). Controller object shows unable to retrieve system status error.
Faceplate of all uploaded objects are also showing cross marks.
