10.8.1 Power-up and Reset

During power-up and reset, the PNC runs diagnostics and initializes its hardware
components. When the necessary hardware components have been initialized and tested,
the PNC transitions to normal operation.

10.8.2 PROFINET IO-Controller Status Reporting

The PNC provides 32 bits of status information to a configured location in the RXi CPU's
reference memory.
The status data consists of the Module OK bit, which indicates the health of the PNC 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 RXi CPU.

Individual device statuses (as reported by the PNIO_DEV_COMM function block) are updated prior to
the All Devices Connected bit. Therefore, it is possible (depending on PNC loading) to see via the
PNIO_DEV_COMM function block that every individual device is connected while the All Devices
Connected bit is not yet set. To avoid this inconsistency, it is recommended that the All Devices
Connected bit be checked first, before checking individual device connection status using the
PNIO_DEV_COMM function block.
For details on using the PNIO_DEV_COMM function block, refer to Section 10.7.2,
PNIO_DEV_COMM Function Block.
