Title: Use of MDS100-BW and I-7017 on same RS485 port?
Post by: garysdickinson on February 07, 2009, 06:14:16 PM

I've got a I-7017 connected to an T100MD1616+ PLC.  I'd like to add the MDS100-BW to the same RS-485 port.

Can the MDS100 co-exist with the I-7017 on the same RS-485?

The two are using different protocols. It could work as long as they don't misinterpret command meant for the other device but it is hard to guarantee until you test it.

A better way is to use an external relay to switch the rS485 pair from one device to another device. That ensure that only the correct device receive the intended commands.
