What communications protocols does LabView support?

[tallenjackson]

A customer of mine is using LabView.  He has asked me if I can communicate to it using a PLC.  Either GE Fanuc or Allen-Bradley.  I need to know what methods of communication that LabView has available to talk to these PLC's.

The short answer is: whatever protocol you want to talk...

I have developed applications talking to AB stuff, modbus (which will cover most PLCs) and even TI's old proprietry PLC protocol. There are lots of tools for making the connection in lots of ways.

What are they specifically needing--or do they know yet?

Mike,

Thank you for the quick response.  This is exactly what I needed to know.

I use the kepware opc server program to talk to the DSC engine and modicon plc's. I have used modbus/tcp, modbus plus, and modbus connections.

Kepware has 80 different drivers for 100's of plc's.
