Labview Machines with AB PLC computer with Rslinx now what? can i communicate with data socket?

[buton]

So i have my Labview( i have made applications client server with datasocket vi)..

i have a machine with allen bradley PLC...and a machine with RSLinx where i conect to the plc to download the programs..

I want to pull information from the PLC so how do i make it happen? i have read about the OPC so what i got from reading is that.. i should conect to via datasocket to the computer with RSlinx who is conected to my PLC...

so what we are saying is that the computer with RSlinx is My datasocket server(opc)?

am i right?

Not sure - but I think you have to have the "RSLinx OEM" version to pass data from the PLC to datasockets...

Rslinx lite will not allow pocket connection. I think any paid version will. You need to configure the topics to allow access to your pocket via opc. Then you can use datasocket. Use ds open outside your loop to improve the read performance. Quality status output will give you different values if the plc is disconnected. It's been a while since I used rslinx with LabVIEW so I can't remember much more, but I hope this is enough to get you started.
Good luck
Michael.
