OPC client connection between System 800xA 18.104.22.168 and System 800xA 5.1 data synchronization
We have two System 800xA, one in version 22.214.171.124 and other one in version 5.1 Fp4 rev D. Between those Systems we have an OPC client connection configuration and PLC connect to send and receive the date in both ways.
When we send information from the plant that has System 800xA version 126.96.36.199 to the System 800xA with version 5.1, some variables doesn't refresh or displays an incorrect value (the first image represents the information read from the OPC client of the system 188.8.131.52 in the System 5.1. The image on the right is the motor that is operating).
The addressing seems to be OK, because we can browse through the data in the System 800xA server and connect the variable. The deploy function works without any issues.
Can you check whether services of PLC connect in xA system is in service or synchronisation state.
Try to restart the services once or create additional service provider (if possible)
Deploy the system from Control StructureHello.
