Diagnostic LEDs
The diagnostic LEDs of a PROFIBUS master and PROFIBUS slaves are described here. The labelling of the diagnostic LEDs on a CX2500 fieldbus module and an Embedded PC with optional interface is identical.
The LED description therefore only distinguishes between PROFIBUS master and PROFIBUS slave.
