Compact Logix communication with Agilent 34420a Micro-Ohm meter

[spireswe 0]

Hello Everyone, I am new to the forum and look forward to working with everyone! For my first post, I am working with a Allen Bradley Compact Logix controller and I a looking to communicate with an Agilent 34420a micro-ohm meter. We currently communicate with these ohm-meters thru GPIB communications. But the ohm-meters also have a RS-232 connection. My question to the forum is "Has anyone ever connected with these devices before using a Logix controller?" Any advice would be greatly appreciated. Thanks,

My question to the forum is "Has anyone ever connected with these devices before using a Logix controller?" No, I have not connected to this device before. However I have connected to a Profibus device using a CompactLogix and a specialty module from Prosoft. Basically, you need a way to establish RS232 communication between the CompactLogix PLC and this device. One way of doing this is by buying a specialty module for the PLC. Rockwell sells a module 1769-ASCII, you can find the manual here:http://literature.rockwellautomation.com/idc/groups/literature/documents/in/1769-in068_-en-p.pdf I have used modules from Prosoft that mount on a CompactLogix and provide Profibus comms. Looking at their website now, I see they have some modules for "Generic Serial ASCII Network", you may want to check if this would work.
