Posted 14 Dec 2017 Morning Guys, For my latest project I need to read a gas sensor via 485 from a Momentum PLC. I've been through the help files, but they seem to only raise more questions than they answer, they only seem to reference PLC -> PLC comms. I've had a play with the 'MBP_MSTR' & 'OUT_IN_MBUS' function blocks, but i can't seem to get anywhere, Has anyone got any examples of reading in data via 485, or can anyone lead me in the right direction?

Posted 14 Dec 2017 Well, just take XXMIT block, setup the Communication port and you will be able to communicate via RS485 port. Share this post Link to post Share on other sites
