Re: [foxboro] PLC interface question

Haven't interfaced a Micrologix to I/A, but I have interfaced them to other
systems.
The 1500 has two ports, channel 0, and channel 1.
Channel 1 can be configured as a Modbus RTU slave.

See appendix E in the instruction set.

You can read the instruction set, manual at:

Subject:    [foxboro] PLC interface question


Hi all,

I've worked with PLC-I/A interfaces in a past life, but I have none in my
current position. We're looking to install an Allen-Bradley MicroLogix 1500
in the utility area, and I'm told it has a built-in "MODBUS RTU" port
(although I don't see that on the AB website). We're running v4.3 so I'm
limited in which interface cards I can use - INI15, INI30, etc. My past
experience is with AB SLC50's. Does anybody have any experience with this
AB MicroLogix 1500 interfacing to I/A?
