We are currently using two types to communicate to AB PLC's. AB-STATIONS,
and FBM224. The best by far is the 224, but unless you've got a CP60 and
are willing to move to v6.5, that isn't an option. The AB Stations which
requires the co-processor, have fallen by the waste side and have become
issues with every software upgrade. With the Integrator 30, you will have
to sacrifice 2 to 3 second delays do loading issues if you plan on grabbing
multiple registry lists. That's where the 224 standout.

We installed a FBM 224 at one of our site connected to a Turbotronics panel
on a Solar C3 turbine. We have be extremely pleased with the communication
interface. It is setup RS232 Modbus getting 356 registers and appears to be
handling it very well. We still hardware any control or external shutdown
functions. Took us just a bit to figure out the transitions.
Thanks

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.

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?
