Cfg Len is the configuration length for the slave with S as the pointer.
RCfg len is that received from the master with S as the pointer.
Ident is the PROFIBUS identification number for the module.
FDL SAP last PTR is the end of all the PDPS data in the SPC3 chip. This value
must be less than 0xFF or there is a memory overflow problem!
Comm Failure mode is that from the configuration file as is the swapping of input
and output data.
Viewing PROFIBUS Status
Enable State
Indicates the initialized state of the MVI56-PDPS module.
