Hey Ausman, Thanks. I'm familiar with this thread and the pdf's, although I got them from all around the web and not your zip file , since its protected with an unknown password. I use the online help files a lot, but they're just not a programming guide, they're more like a……..software guide ? -
Yam, please have a look at point 21 in this pinned topic. cheers, Aus -

Yes* and yes. The manual is clearly wrong. The Ethernet I/O is not a Unitronics-manufactured product, and the manual is not an original complete creation of the Unitronics documentation department. It is a modified re-issue of what the manufacturer supplied. So somebody missed something. Too many late nights and deadlines on the tech writers, I would suspect. Thanks for pointing this out. Flex has already flagged Cara Levy the Documentation Queen so hopefully it gets corrected and updated soon. Joe T. * - that is correct for a two-wire device. Some devices require separate power and generate their own current rather than modulating their supply. -

nd this is what i find difficult to understand. Normally I connect my two-wire sensor to + 24V and i.e. input CH1 (on picture), but this looks like the sensor shall connect +24V to CH1 and the low side to 0V ?
