Diagnostic word
If GSDML version 2.1 or higher is integrated in the configurator, a status and control DWord (double word) is integrated in the DAP. Additional functions can be used here:
- Measurement of the K-bus cycle time
- K-bus cycle counter (is incremented after each K-bus cycle)
- K-bus error, error code and error argument (see K-bus diagnostic LEDs)
- K-Bus reset
- Bus Coupler reset
Status DWord (input word of the PLC)
The status DWord shows diagnostic information.
