Signal status LEDs

This manual only describes the LED signal statuses of the EtherCAT modules. Information for the frequency
inverter LEDs (SK 200E) can be found in the relevant manual (BU0200).
The statuses indicated by the LED can be read out with the aid of a parameterisation tool from Getriebebau
Nord (NORDCON software ParameterBox) and also of course via the information parameter (P173) “Module
Status” (See Section 6.2.2 "BUS module information parameters, general (P170)").
