I've heard in the past that its a bad idea to use a ENBT module on your regular network to use as both LAN connections (for remote programming) and as a Distributed I/O. With this in mind, I've got a spare ENBT and I was going to install it for its sole purpose of Distributed I/O. Right now this would connect to two Flex I/O units and a IRC5.
From what your saying it sounds like its ok to use one module to do both? If I use a managed switch could I pull this off (and be cheaper)?
