I had not looked closely enough apparently, this indeed seems to be the case.The ENBT looks like a separate PLC (L71) that your communicating with, probably with producer/consumer tags.
Indeed.Think we all agree to change the PointIO address in the PLC program to 192.168.1.40
Although your meaning is clear enough, I'm going to have to nitpick -- BOTH of these sets of addresses are 'PRIVATE'.I haven’t read all the details of this discussion but it appears that you have the modules set to the public address. Shouldn’t these be set to the private address? The nat router will translate the address PRIVATE to public.
The IANA (Internet Assigned Numbers Authority) reserves 10.xxx.xxx.xxx and 192.168.xxx.xxx as private address spaces (and also 172.16.xxx.xxx through 172.31.xxx.xxx).
The 10.201.104.xxx addresses here are likely part of a larger plant network, whereas the 192.168.1.xxx are addresses on a smaller machine network, but neither is a 'public' network.
