Siemen's S7-417H redundant plc

Thread Starter

I have two siemens S7-417H cpu’s that run as a redundant pair. On the project tree menu both cpu’s are shown but only one S-7 program shows under one of the cpu’s. I have made programming changes to this S7-Program.

My questions:

Do I need to somehow save this revised program to the backup cpu?

If so, how do I do it?

The cpu’s have a memory card in each cpu.

How do I save the revised program to these cards?
