MVP 2021 Flex727 Posted September 23, 2016 MVP 2021 Report Share Posted September 23, 2016 Anyone ever tried to communicate with one of these devices with Unitronics PLC? Ideally, I'd like to be able write to the relay address from the PLC using Ethernet. http://kmtronic.com/modbus-relays.html Quote Link to comment Share on other sites More sharing options...
MVP 2021 Joe Tauser Posted September 23, 2016 MVP 2021 Report Share Posted September 23, 2016 I've never used one of those but they look really simple. How much are they? Quote Link to comment Share on other sites More sharing options...
MVP 2021 Flex727 Posted September 23, 2016 Author MVP 2021 Report Share Posted September 23, 2016 I think they can be obtained for about $40 each. We always struggle to have enough digital outputs and these look like an inexpensive way to add more. The caveat is that we have to be willing to endure the delays as compared to a relay attached to an I/O module (and potential reliability issues?). I should have one in hand in a couple of weeks and will play with it to see what I can make it do. Quote Link to comment Share on other sites More sharing options...
MVP 2021 Joe Tauser Posted September 23, 2016 MVP 2021 Report Share Posted September 23, 2016 I dug deeper into their website - 59 Euros out of Bulgaria. I'd be curious if they have a US sales channel. Joe T. Quote Link to comment Share on other sites More sharing options...
