Memory modules
In order to use the PLC functionality, the memory module MM340 or MM440 (licence: "PLC") must
be plugged in the controller. Saving with mains failure protection of the IEC61131-3 program into
another memory module is not possible.
The following table compares the storage capacities and functions of both memory modules:
