There are three options to talk to your PLC:

1. If there is a documentation available for the serial protocol that is used for the PLC, you could program the communication by your own by using low-level VISA functions in LabVIEW.
   
   
2. Find out the name of the serial protocol that is used for your PLC (sorry, I don't know this PLC and I haven't found it on the Moeller webpage). Then search the web for a LabVIEW driver for this protocol. You may also ask Moeller if they provide a LabVIEW driver
   
   
3. This is the most simple option, but it may involve some software licence fees. In LabVIEW you can use the DataSocket API or front panel binding (even simpler), to connect to an OPC server. Moeller should provide an OPC server for their PLCs, which gives you an easy to use interface. To get an idea how to use this method, please refer to the shipping examples (search for OPC).

I hope this helps,

I have the same problem , comunication with Easy control relay 800 series, I have bought an Easy 2004 DP and the documentation from Moeller but I had yet found any solution .

If you want I can sent you the manual to look on it , if you want.

Another way to comunicate is by direct programing in Easy soft a serial protocol , in this way you can comunicate with the serial port available on the front of the device.
