Synchronise AC800F time with an external time server
In our project, we want to synchronise the time of AC800F controller with an external freelance OPC server (installed in a different machine than control builder). The version of Freelance is 2013 SP1. We entered the IP adress of the controller AC800F (which is the lowest on the network) into the OPC gateway configuration but it doesn't work.
My question is simple : How can we synchronise the time between our freelance OPC server (which is master) and the AC800F (wich is slaved)?
Firstly - if You want to sync time of controller from OPC server You need to disable time synchronization on the server. You don't want to create a "time sync loop" in which the controller sets time on OPC server and server set it back on controller.
Then set time on OPC server and set Enable with proper IP address in gateway configuration in Freelance Engineering. Load the station.
In most cases this is enough. Sometimes restarting the OPC server helps, if the synchronization won't work just after this changes.
You can check if the controller is synchronized in web server under Time sync info.
Hope this helps,
