Aurimas Posted August 10, 2017 Report Share Posted August 10, 2017 Hi, I have Unistream 10 as a master and multiple slaves (8) over Modbus RS485. What device do I need to connect all the slaves into one master? Quote Link to comment Share on other sites More sharing options...
MVP 2023 Joe Tauser Posted August 13, 2017 MVP 2023 Report Share Posted August 13, 2017 Twisted pair wire. There is wire specifically made for RS485 but I've found Ethernet cable works, too. I looked through the UniLogic Help and there's really not much on hardware connections. I'd recommend downloading Visilogic and searching it's Help for RS485. The Visilogic Help is much more thorough on this topic. With that said, it's really not this forum's place to be a teacher of basics like RS485. We just use it as a means to an end. It's on you to at least Google the topic - there's much more complete information available on websites of companies that make their living selling communication hardware and converters.
