Please, kindly help me give idea on how to resolve this error :
MMS SERVER DID NOT RESPOND!.
This error pops up when when I open the Control Builder in ABB 800xA version 4.1.
Whenever this error pops up the the Control Builder cannot go online and cannot download to the AC 800M Controllers.
I have tried stopping and restarting services but the problem persists.
I also checked OPC server connections, everything there is fine.
There is communication with the controllers through OPC.
I need to download changes to the controllers.
Could someone please help me tell me what to do as soon as possible.
Thank you very much in advance!
