You have to be in Service Structure to do this.
Expand Services->Softpoint Server. Then expand the PLC Connect Service Group you want to do the swap with.
We will be using “SG_PLC_Net2” service group for your example.
Uncheck the “Enable” checkbox and click the “Apply” button to stop polling from the PLC Connect server TEST-PLC-88.
After a while the current status will change from “Service” to “Undefined” (see image below). Once that happens, you can restart/power cycle that PLC connect server (TEST-PLC-88).
Note that when we perform this PLC Connect server swap, there will be no outage on the poll and operations will not see any outage in their graphics.
Click on the redundant node server TEST-PLC_89 (right below it). Notice that it changes its current status from “Standby to “Service”. Which means that the DCS is polling though this server now.
Once the TEST-PLC-88 PLC connect server is restarted, check the “Enable” checkbox. It will start to synchronize with the active PLC connect server TEST-PLC-89. When you bring the PLC Connection up from “Undefined”, it goes from Undefined -> Initialise – > Ready -> Synchronizing -> Standby.
Once the synchronization is done, TEST-PLC-88 will be in standby mode.
