IAC timeout (Normal) 16#20020, when trying to establish IAC between 172.16.1.40 & 172.16.80.171 AC800M Controller
In one of the site, we are trying to establish IAC between 172.16.1.40 & 172.16.80.171 AC800M Controllers, but we couldn't do it.
Communication variable status at receiving controller is 16#20020(IAC Timeout).
Both controllers are in same 800xA System. And both are connected to same OPC Server for AC800M connection status is GOOD.
System : 800xA6.0.3.2 version
We are doing the 800xA4.1 to 800xA6.0.3.2 system upgrade, we cannot make both controllers of same IP series only to establish IAC.

I cant answer exactly but the suspect is difference in the third number of IP address. I think problem is in routing in two different Control network areas. Try to change IP address of the first controller to 172.16.80.40, if it is possible. Do you have RNRP routing enabled in Connectivity servers?
