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