Status Reporting
The PNC001 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.

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 entitled Status Reporting in the RX3i PROFINET I/O Controller Manual, GFK-2571.
