1.
Mount the Master Unit on the PLC system (refer to
).
• Treat the Unit as a CPU Bus Unit.
• It can be mounted to a CPU Rack or Expansion Rack.
• Number of Units: 16 (Max).
2.
Set the Unit No. (UNIT No.) for the PROFIBUS-DP Master Unit (refer to
).
3.
Connect a PC or a Programming Device to the PLC and turn ON the power
supply to the PLC.
4.
Generate the I/O tables and restart the PLC (refer to
5.
Install CX-Profibus, and the DTMs on to the PC.

1.
Wire the network, to connect the PROFIBUS-DP Master unit to the slave
stations.
2.
Turn ON the PLC power supply and the power supplies of the Slave station
on the network.
3.
In CX-Profibus, create a network and define the parameters and I/O con-
figurations for the PROFIBUS-DP Master Unit settings and the allocated
Slave stations. Determine the baud rate and the bus parameter setup.
Make sure that the “Go to OPERATE mode“ option is selected, to force the
Unit to OPERATE mode upon a PLC mode change to RUN / MONITOR
mode.
4.
Download the network configuration to the PROFIBUS-DP Master Unit. Af-
ter downloading the configuration, CX-Profibus will restart the PROFIBUS-
DP Master Unit.
5.
After restarting the PROFIBUS-DP Master Unit it will automatically start
communication.
