Labview - siemens s7200

[tecav impianti srl]

I would interface Labview 5.0 with Siemens S7200 plc. Anyone had some
experienced?
Thanks.

Is this model made by them, or is it one of the PLC product lines they bought from other people (i.e. Texas Instruments)? If it's the latter I have native drivers I can send you, other wise the way to approach it would be to use MODBUS.

Do a search on the discussion group, I posted a set of MODBUS drivers to someone else within the last 30 days.

I did it by means of a free OPC Server. It was Kepware KepServer v4.0,
which has the only limitation that it stops after 2 hours of
execution. You have to connect your s7-200 to the Pc via the PC/PPI
cable. From the KepServer you can assign the inputs/outputs/marks to
many OPC tags: Select Channel, Device and I/O you want.
Then in Labview, in the control or indicator you want to read/write
the PCL registers, you must set the DataSocket conection for the OPC
data exchange:
- right-click the object (control or indicator...)
- select DataOperation / DataSocket Connections
- browse to the OPC connection you've created in the Kepserver

Now this control/indicator is related wit
h the PLC, and it works
well!!!
