How can we switch over the hot standby PLC by using software and without touch the run/stop switch on the PLC? |

Hello,
Please check section 11.2.2 of THIS manual: 11.2.2 Displaying and changing the system state of a fault-tolerant system Procedure: 1. In SIMATIC Manager, select a CPU with existing MPI connection. 2. Select the PLC > Operating mode menu command. Result: The "Operating mode" dialog shows the current system state of the fault-tolerant system, the operating states of the individual CPUs, as well as the current position of the mode switches on the modules. The CPU that was selected in SIMATIC Manager when the menu command was executed is the first one displayed in the table. I hope it helps, hdhosseini |
