Hi Cristian, Before investigating the WinCC redundancy function, I have one question on the physical connection between OS server (WinCC application / WinCC application Standby). Which methods are you using for redundancy synchronization for OS servers? 1. Serial connection via COM1 port of OS Server. 2. Dedicated network adapter for redundancy. You may check this setting in SIMATIC Shell redundancy settings. You may also check this configuration in WinCC explorer redundancy editor. If you are using method 1 to perform synchronization , please make sure your Serial Cable has correct pin assignment. Siemens is using special pin assignment. Serial Cable Pin Assignment for WinCC Redundancy You may solder the serial cable yourself or purchase it with siemens via this part number "6ES7902-1AC00-0AA0" "SIMATIC S7/M7, cable for point-to-point connections RS232C-RS232C 9-pole sub D socket respectively 10 m length" If you are using dedicated network adapter and sync via industrial ethernet, then make sure the settings you configured in Simatic shell is correct. Let us know these have been checked before I continue to advice more. Hope this is helpful for you.
