Hi everyone ! I have a question on WinCC redundancy servers with several clients.
The following is the Sys Log of WinCC:
255,22.02.2008,18:52:30:808,1012200,4,,SERVER-A,RedundancyAgent,Outage detected reason 4
255,22.02.2008,18:52:47:917,1012201,4,,SERVER-A,RedundancyAgent,End of outage
255,22.02.2008,19:07:59:801,1012209,4,,SERVER-A,RedundancyAgent,End of synchronization
I found that the two redundancy servers has changed over suddenly during the time of "Outage detected reason 4". I have checked the manual of WinCC. It does not mention what is the outage reason 4. I only checked the message code "1012200" means "Partner station is failed". What is the meaning of "reason 4"?
p.s. I also checked have "reason 1", how many "reason" does it have?
