FX3-MPL1 system plug
The system configuration for the entire UE4740 systems is only saved in the system plug.
On the replacement of the PROFINET IO gateway UE4740 this situation has the advantage
that it is not necessary to re-configure the system.
Connected EFI-compatible devices must be re-configured as per CDS parameter settings, if
necessary, when they are replaced.
The data saved in the system plug are also retained on an interruption in the supply of
power.
