NOTE
If P0971 is used to start data save from the RAM to EEPROM, then after the data
has been transferred, the communications memory is re-initialized. This means that
communications via USS as well as also via the CB board are interrupted for the
time it takes to reset:
The connected PLC (e.g. SIMATIC S7) goes into stop
The STARTER start-up program buffers the communications failure
For the DriveMonitor start-up program, "NC" (not connected) or "drive busy" is
displayed.
The "busy" text is displayed at the BOP operator panel
After reset has been completed, for the start-up programs STARTER and
DriveMonitor and the BOP operator panel, communications are automatically re-
established.
