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

This task includes the following steps:

• Make the physical connection

• Set a static IP address

  In a network with a DHCP server, the IP address may change over time. For our application, we need a static IP address.

• Enable the router function

  The router function is needed to forward incoming packages to the FP0H PLC.

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

(Replace the IP addresses in this example with the addresses that match your network configuration.)

Make the physical connection

1. Connect a LAN cable from the router to the FP‑I4C unit. Use the top ETH0 connector, which is set to DHCP by default.

2. Connect your PC to the same router to find out the IP address of the FP‑I4C unit and to configure the unit.

   Follow the instructions on how to connect the FP‑I4C unit via DHCP server (see "Related topics").

Set a static IP address

1. Open your browser and enter the URL https://[IP address]/machine_config. Replace [IP address] with the IP address of your FP‑I4C unit (e.g. https://192.168.100.10/machine_config).

2. Log in with the default or your modified administrator credentials.

   The user name is "admin", the default password is also "admin".

3. Select Network > Network Interface.

4. Select EDIT and then DHCP disabled for eth0 so that DHCP is disabled for both Ethernet connectors.

   Make the following settings:

   Address: 192.168.100.10

   Netmask: 255.255.255.0

   Gateway: 192.168.100.1

Enable the router function

1. Select Services > Router / NAT / Port forwarding.

2. Select EDIT and turn on the Enabled switch.

3. Select SAVE to save your settings.

Configure the RS232 COM1 interface to the FP0R PLC

1. Select Application Settings to go to the application settings area.

2. Go to COM Interface and select Start wizard to start the PLC connection wizard.

3. Select Simple mode and Continue.

4. Select COM1 RS232 and Continue.

5. Select a baud rate of 115200 and Odd parity.

6. Enter port number 9094 (must match the application port setting in Corvina).

7. Select Finish.

   All packages received on the specified port are now forwarded to the PLC via the serial interface.

8. Save your configuration.

   After about 10s you can test your connection.

9. Select Test RS232.

   You should receive a message that the FP0R PLC has been successfully connected to the RS232 interface. If the connection fails, refer to the troubleshooting section for advice.
