hello jerahmeel; I am afraid we need nore detailed information before we can suggest any tests or solutions to your problem. Which version of PCS 7 are you working with? What model/part number of S7-400 are you deploying? When you speak of server redundancy, o you mean ES redundancy (on the PLCs) or OS redundancy (on the WinCC SCADA side)? When you say you transfered from server 1 to server 2, how did you proceed? Have you looked at the diagnostic files of your servers? For the s7-400, they are located in the diagnostic buffer of the CPUs, for WinCC you could open WinCC_sys.log and WinCC_SSrtart.log:

Hi Daniel, Thank you for your reply. We are using PCS7v8.2. We are not deploying new controllers. We have OS redundancy. When we stopped the services of server 1 it transferred to server 2 then the plant shutdowns. Thanks for the information. Will check for the logs. Regards, Jerahmeel |
