How to Enable Ethernet3 port in Redundant Freelance Controller
I have PM 902F redundant controller, I have enabled Ethernet1 and Ethernet2 for redundacy. For using Line B, I have Set Ethernet 3 as Redundant Network and entered IP address in Primary controller, while doing the same in Redundant controller, the settings are not getting saved and an error message "Invalid Config" shows on LCD display.
I have entered the following IP address:
Primary Eth1 - 172.16.1.3
Redundant Eth1 - 172.16.2.3
Subnet - 255.255.240.0
Primary Eth3 - 172.16.17.3
Redundant Eth3 - 172.16.18.3
Subnet - 255.255.240.0
I have searched this forum & ABB sites for technical document about settings needed for Enabling Line B, but I couldn't find any.
Some please help me how to use Ethernet 3 as Line B for Freelance System with Redundant PM902F Controller.

Seems to me the subnet mask does not fit to the IP addresses on Eth3.
To keep the IP addresses the subnet mask needs to be FF.FF.E0.00 or in decimal 255.255.224.0
Alternatively use 172.16.5.3 and 172.16.6.3 for Eth3
