Port page

On this page, you can test the serial connection to the PLC and set redirects from Ethernet to other interfaces of the FP-I4C unit.

In this section:

Test the connection to the PLC
Check whether the communication with the control device (PLC) can be established.
Understand and configure redirects
To configure redirects from Ethernet to another FP-I4C interface, you must open and configure a TCP port for each interface.
Restrict address ranges for open ports
For open ports, you can enable and disable access to certain address ranges.
Restriction rules
A number of rules apply when you limit access to certain address ranges.
Make Modbus/TCP gateway settings
You can turn the FP-I4C unit into a Modbus/TCP server that listens to the specified port.
Addressable memory areas for interface INTERN
The addressable memory areas in the FP-I4C unit can be accessed via Modbus/TCP or via the script function.
