The module provides information on diagnostics and troubleshooting in the
following forms:
LED status indicators on the front of the module provide general information
on the module's status.
You can view status data contained in the module through the
Configuration/Debug port or the Ethernet port, using the troubleshooting and
diagnostic capabilities of
ProSoft Configuration Builder (PCB)
.
You can transfer status data values from the module to processor memory
and can monitor them in the processor manually or by customer-created
logic. For details on Status Data values, see Status Data Table.

Troubleshooting the operation of the PROFIBUS Master ports can be performed
using several methods.
The first and quickest is to scan the LEDs on the module to determine the
existence and possible cause of a problem. This section provides insight into the
operation of the PROFIBUS Master Port status LEDs. Information on the
module’s other LEDs can be found in the ProLinx Reference Guide.
