Configure two MultiLink Modbus ports on the same port in a fx controller.
On a FX substation side go to Settings -> Ports
Configure some port to be Modbus UDP. Set the sending delay if needed.
Then go to the Programming -> Modbus Devices
Create a new device with desired register type, starting register and number.
Set the TCP/IP module, enter the MultiLink IP address and IP port corresponding to it's physical RS485 position (+10000)
Following example illustrates the Modbus AHU with address #60 connected to the MultiLink's (IP 192.168.11.97) RS485 port #1
Cobnfiguration at the MultiLink side:
MultiLink Remote IP port corresponds to the FX substation's Serial port number (+10000)
In the same way any other Modbus device can be configured to the same FX substation port #9:
Following example illustrates the Modbus AHU with address #61 connected to the MultiLink's (IP 192.168.11.98) RS485 port #2
