Procedures Prior to Starting Communications

1,2,3...
1. Mount the Master Unit on the PLC system (refer to 2-2 Installing the CS1/
CJ1W-PRM21 Units).
• 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 Master Unit (refer to 2-3-1
Selecting a unit number).
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 2-3-2 Creating an I/O
table).
5. Install CX-Profibus, and the DTMs on to the PC.
Use the following procedure to configure the Unit using CX-Profibus:
1. Wire the network, to connect the PROFIBUS Master Unit to the slave de-
vices.
2. Turn ON the PLC power supply and the power supplies of the slave device
on the network.
3. In CX-Profibus, create a network and define the parameters and I/O con-
figurations for the PROFIBUS Master Unit settings and the allocated slave
devices. 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 OP-
ERATE mode upon a PLC mode change to RUN / MONITOR mode.
4. Download the network configuration to the PROFIBUS Master Unit. After
downloading the configuration, CX-Profibus will restart the PROFIBUS
Master Unit.
5. After restarting the PROFIBUS Master Unit it will automatically start com-
munication.
