1-4-2 Preparations for Communications
1
Mount the Master Unit on the NJ-series controller unit (refer to 2-2 Installing the PROFIBUS
Master Unit).
• 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 2-1-3 Switch Settings).
3
Connect a PC to the NJ-series controller unit and turn ON the power supply to the CPU.
4
Create the Unit configuration (refer to Sysmac Studio User Manual (Cat. No. W501).
5
Install CX-ConfiguratorFDT and the DTMs to the PC.
Use the following procedure to configure the Unit using CX-ConfiguratorFDT:
1
Wire the network, to connect the PROFIBUS Master Unit to the slave devices.
2
Turn ON the CPU power supply and the power supplies of the slave device on the network.
3
In CX-ConfiguratorFDT, create a network and define the parameters and I/O configurations 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 OPERATE mode upon a CPU mode change to RUN mode.
4
Download the network configuration to the PROFIBUS Master Unit. After downloading the con-
figuration, CX-ConfiguratorFDT will restart the PROFIBUS Master Unit.
5
After restarting the PROFIBUS Master Unit it will automatically start communication.
