Status Reporting

The PNC001 module and any embedded PROFINET Controller both provide 32 bits of status information to a
configured location in the PACSystems 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 PACSystems CPU.
Status Bit Definitions
Bit Name
1 Module OK
2 Port1 Link Up
3 Port2 Link Up
4 Port3 Link Up 8
5 Port4 Link Up 8
6 Reserved
7 Port3 SFP OK 8
8 Port4 SFP OK 8
9 All Devices
Connected 9
10 Reserved
11 MRP Enabled
12 MRP Role
13 MRP Ring Status If MRP is enabled and the PROFINET Controller is currently the MRM:
14-32 Reserved
8 Applies to PNC001 module only. Bit is set to zero on embedded PROFINET Controllers.
9 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, refer to the section entitled PNIO_DEV_COMM Function Block.
GFK-2571N
Indicates the health of the PROFINET Controller.
1 indicates the PROFINET Controller is functioning properly.
0 indicates the PROFINET Controller is not functioning properly.
1 indicates the port is connected to another device and is operating correctly.
0 indicates the port is not connected to another device, the port has an error
preventing communications, or the SFP cage is empty or has an incompatible SFP
device.
For CPE100/CPE115, Port1, 2 & 3 Link Up status indicates the LAN2 Port2, 3 & 4 Link
Up status.
Always 0.
Indicates the health of the SFP plugged into 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 into 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 PROFINET Controller is currently an MRP client (MRC).
1 indicates that the PROFINET Controller is currently the MRP Manager (MRM).
If MRP is not enabled, this bit will be set to 0.
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 PROFINET Controller is an MRC, this bit will be set to 0.
Set to 0
