How can I connect LabVIEW 7.0 with an AB PLC (micrologix 1500)

[barron]

Hi, I have an AB PLC (micrologix 1500), but I don´t know how connect it to LabVIEW, I mean, I want to aquire data from PLC (analogous data)and I want to write on it too,(using LabVIEW 7.0), Can you send to me an example about this application or explain to me how can I do this application?
thanks you.
(sorry, my english so bad)

I haven't done this personally, but I remember many discussions here on talking to AB PLCs. Search this site for "Allen Bradly" and you should probably come up with at least a few relevant results.

"I want to aquire data from PLC ... and I want to write on it too using LabVIEW 7.0"

Do you have plain LabVIEW or LabVIEW + DSC (i.e. Datalogging and Supervisory Control module in the Prof. Control Development Suite)?

... and do you have Allen Bradley's RSLinx?

you just need an OPC server (such as RS Linx) to talk to the PLC, and use datasocket with the opc url to talk to the server.
