Commissioning The Field Distributor - Wieland podis MOT FP C Operation Manual

5. Commissioning the field distributor

Before the initial commissioning, check the following points:
• Is a unique PROFIBUS address set? No multiple assignment of the same address.
• Are the internal terminals inserted?
• Is the cover plate attached without pinching any connecting cables?
• Is the supply voltage of 400 VAC and 24 VDC secured via the penetrating contact
screws?
• Is the polarity of the 24 VDC supply correct?
• Is the PE conductor connected?
• Are the initiators correctly connected at the M12 sockets? Is the assignments of inputs
correct?
• Are unused M12 sockets fitted with a cap?
• Are the M12 PROFIBUS cables correctly connected?
• If the field distributor is connected at the end of the PROFIBUS cable, is a terminating
resistor connected at the M12 socket "DP-OUT"?
• Have all the necessary settings and any wiring been made at the MOVIMOT, and has the
MOVIMOT housing been reinstalled?
• Is the hybrid cable connected to the MOVIMOT?
• Is the PROFIBUS master connected? Has the hardware project planning been per-
formed?
• Is the controller set to STOP or has a tested program been loaded?
After this check has been completed, the voltage can be switched on.
It is recommended to switch on the 24 VDC supply first, followed by the supply of the PLC
or the PROFIBUS master.
If the system does not run without faults after switching on the supply voltages and
components, you should perform an error determination.See the chapter "Diagnostics
(and fault removal)".
