If it does talk Modbus RTU, you can interface via a FBM224 card. Just
installed one of these at one of my sites.
Went pretty well, except the card does not support double precision numbers
(4 registers instead of 2 for a float).
Also, can have redundant ports, but not redundant cards talking to the same
Slave device.

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?
