Troubleshooting
In this chapter, we describe how to use the adapter’s indicators for
troubleshooting.
Locate the two bi-color indicators on the front panel of the adapter.
They show both normal operation and fault conditions in your Flex
I/O PROFIBUS system. The indicators are:
•

•
PROFIBUS – this indicator provides communication link status
Use the following table to determine the indicator conditions and
status.
