CLICK Port 3 MODBUS Configuration for RS-485
The following configuration example is specific for CLICK PLC CPUs.
• Configure the communication port before writing communication instructions into
the logic program.
• In CLICK programming software, open the “Comm Port Setup Details” dialog box
by choosing the Setup menu, then Comm Port Setup, then Port 2 Setup.
• From the “Port:” list box, choose “Port 3”.
• For the “Protocol:” list box, select “Modbus”.
• Set the “Node Address” to “1” to make the CLICK PLC a MODBUS master.
• Set the “Baud Rate” to “19200”
• Set the “Parity” to “Odd”.
• Set the “Stop Bit” to “1”.
• Set the “Time-out Setting” to “500ms”.

The communication port settings are saved in the project file. The project must be
transferred to the CLICK PLC in order for any port setting changes to take effect.
