Does anyone have a driver to small Mitsubishi PLC's

[Greg Caesar]

National Instrument does not develop direct drivers to PLCs from LabVIEW. However, we do have an OPC Server application called "Lookout Protocol Drivers" that ships on our "Industrial Automation OPC Servers CD" product. Lookout Protocol Drivers, (or LPD for short) is an OPC Server application that handles communication with the PLC hardware. As an OPC Server, it publishes the values of every PLC register via OPC so that any OPC client application on the network can read/write the PLC registers. For NI software products, datasocket functions can be used as an OPC client, and allow you to read or write to all the PLC registers (ie channels).

For a list of supported PLCs, please follow the link below.

You can talk to any Mitsubishi PLC large or small using the 'MX component' communication protocol from Mitsubishi. I have had great success in communicating to thier PLCs using LabVIEW with very little coding in both the PLC and LAbVIEW. If you would like more info,including examples, I am more than willing to help.

Is the LPD free product?

If you have some example, can you please post it. I am trying to communicate with a Mitsubishi PLC Fx1s via RS422
