I've had a similar issue. My problem was a "Access Point" connection to the controller which was removed during an upgrade. My symptoms: 1. Alarms were syncing OK. (Connection to redundant Master seems okay) 2. If I started graphic runtime on computer with red indicator it had no values from the PLC (or one of the PLCs I guess depending on your setup). Only Yellow warning signs indicating bad data. 3. Disabling the Master caused the clients to switch to partner, but then the clients did not have data from the PLC connection (exactly as the Partner did not have data). 4. When the master was re-established, the clients switch to it. Solution: Control Panel > Set PG/PC Interface: Select the access point configured in the project (S7ONLINE by default). Select the adapter from which you'd like to make the PLC connection. ------------------------------------------------------------------------------------------ |
