Communications Card Description ZB4-604-IF1, PROFIBUS-DP 5-13
Moeller 07/01 AWB-C2700-1347GB
8 Commissioning
1. Connect the COM PORT of the ZB4-604-IF1 to the appropriate communications port on the PLC. For this
use the special communications cable of the PLC.
2. Switch on the power supply. Active communication is started as soon as the first operating mask of the
loaded project is displayed.
3. When communication with the PLC is active, the green ACTIVE LED on the ZB4-604-IF1 will be lit.
Once communication has ended, the ACTIVE LED will go out.
The red ERROR LED will be lit if no correct data exchange with the PLC was possible.
Additional points on commissioning refer only to errors; none of the LEDs are lit or the red
ERROR LED lights up.
Otherwise commissioning at this point has ended directly.
4. If none of the two LEDs light up, this is probably because a driver was selected that is not supported by
the current firmware of the ZB4-604-IF1 In this case ask Support about newer versions of ZB4-604-IF1
and note the error messages in the destination hardware.
Other points on commissioning only refer to errors (red ERROR LED).
5. Check the communications cable (test with ohmmeter) using the diagram for the PLC used.
6. If the red “ERROR” LED is only lit temporarily, this indicates faulty error transfer. Check whether the
cables have been prepared and connected as described.
