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.
Bit Name
1 Module OK
Port1 Link Up 1 indicates the port is connected to another device and is operating correctly.
2
3 Port2 Link Up 1 indicates the port is connected to another device and is operating correctly.
4 Port3 Link Up 1 indicates the port is connected to another device and is operating correctly.
5 Port4 Link Up 1 indicates the port is connected to another device and is operating correctly.

* 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 "RX3i CPU Operations for
PROFINET" in chapter 4.
