IC695PNC001-AJ PROFINET Controller Module
GFK-2573K
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.
