Status Reporting
The PNC provides 32 bits of status information to a configured location in the RX3i CPU's reference memory.
The status data consists of the Module OK bit, which indicates the health of the module itself, a status bit for each
external port, and a bit that indicates the connection status of the configured devices.
All Status bits are active high. The status location may be configured in %I, %Q, %AI, %AQ, %R, %G, %T, %M or %W or
I/O Variable reference memory in the RX3i CPU.

It is recommended that the All Devices Connected status bit be checked first to determine whether all devices belonging to
the PNC are functioning. If this bit is 0, indicating that one or more devices is not OK, the PNIO_DEV_COMM function block
can then be used to determine which specific devices are not communicating. For details on this status bit, refer to the section,
Status Reporting in GFK-2571, RX3i PROFINET Controller Manual.
Indicates the health of the PNC module.
1 indicates the module is functioning properly.
0 indicates the module is powering up or has failed.
1 indicates the port is connected to another device and is operating correctly.
0 indicates the port is not connected to another device or the port has an error preventing
communications, or the SFP cage is empty or has an incompatible SFP device.
Reserved. Always 0.
Indicates the health of the SFP plugged in port 3.
1 indicates that the SFP matches configuration and is operational.
0 indicates that either the SFP does not match configuration or is not operational.
Indicates the health of the SFP plugged in port 4.
1 indicates that the SFP matches configuration and is operational.
0 indicates that either the SFP does not match configuration or is not operational.
1 indicates all configured devices are connected and communicating over PROFINET.
0 indicates no devices are configured or one or more configured devices have not established
a PROFINET connection.
Always 0.
0 indicates that MRP is not enabled.
1 indicates that MRP is enabled.
If MRP is enabled:
0 indicates that the PNC is currently an MRP client.
1 indicates that the PNC is currently the MRP Manager.
If MRP is not enabled, this bit will be set to 0.
If MRP is enabled and the PNC is currently the MRM:
0 indicates that the ring is open (ring broken).
1 indicates that the ring is closed (ring complete).
If MRP is not enabled or if the PNC is an MRC, this bit will be set to 0.
