In one of the ESD Controller, we have 2 SIL3 apllications, Out of that one is showing bad Quality on HMI
We have 2 SIL3 apllications in ESD controller, one is showing GOOD status on HMI whereas Other one BAD. Process is running and we could see the application running in controller. Moreover, I can see the Values from Controller using MartiKon OPC server.
This particular problem, we could see once we have restarted primary connectivity server.
we face same problem and we download the application with cold restart option.try this i hope your porblem will solve.
Normally Connecitivty restart only help you when your values stuck on HMI but this problem was 5.0 and ABB Solve this in 5.0 Rev E.
