Diagnostic LEDs

The diagnostic LEDs of a CANopen master and CANopen 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 CANopen master and CANopen slave.
