Step 3: Connect the FP‑I4C unit to the network

This task includes the following steps:

• Make the physical connection

• Configure the FP‑I4C unit's RS232 COM1 interface to the FP0R PLC

• Enable COM2 RS485/RS232 for communication with the KW9M power meters

• Enable COM4 ETHERNET for communication with the KW2M power meters

Make the physical connection

Connect your PC to the FP‑I4C unit and set the IP address of the PC, e.g. 192.168.0.10 (see "Related topics"). The PC must be on the same subnet as the FP‑I4C unit.

Because we are using static IP addresses, connect the LAN cable to the ETH1 connector of the FP‑I4C unit.

Configure the RS232 COM1 interface to the FP0R PLC

1. Open your browser and enter the URL https://192.168.0.1/fp_config.

   Depending on your browser, an insecure connection warning may be displayed. Follow the instructions in your browser to accept the connection. You will then be forwarded to the Web interface of the FP‑I4C unit.

2. Go to COM Interface > COM settings - FP‑I4C and enable COM1 RS232.

   Keep the default settings (Protocol: MEWTOCOL, Autobaud: Enabled, Baud rate: 115200, Parity: Odd, Timeout: 2000).

Enable COM2 RS485/RS232

1. Enable COM2 RS485/RS232.

2. Make the following settings (keep the default settings for all other parameters):

   Protocol: MEWTOCOL

   Autobaud: Disabled (only PLCs can respond to status requests)

   Baud rate: 19200

Enable COM4 ETHERNET

1. Enable COM4 ETHERNET.

2. Make the following settings:

   Protocol: MODBUS

   Timeout: 2000

   IP address: 192.168.0.0

   Port: 502

   Address offset: Enabled and set to 0

3. Save your configuration.
