labview with plc(siemens)

[hakan_s]

Hallo,

i want to know, if it is possible to write a program with labview; and send it with TCP/IP Connection to the PLC.

i'm using Siemens s7.

for example;

u m 1.0

u m 1.1

=a 1.0

i want to write this code from labview to plc. i dont want to use simatic;

or i have the code (program) and i want to write more network in plc.

Thanks

Hakan

You can write a program in LabVIEW, that communicates with a PLC via Datasocket. Datasocket can communicate with the OPC-Server of the PLC. It is not possible to download a LabVIEW VI to a PLC, so that the VI runs on the PLC. The VI will run on a computer, that communicates with the I/Os of the PLC.

You can find an example attached to this message.

As an alternative, you could use a Fieldpoint system instead of your PLC. You can DIRECTLY download VIs to a Fieldpointsystem. Here you can find morte information about fieldpoint:

thank you very much for your reply.

but i couldn't open VI, because i use Labview 7.1

is it possible that you change VI for Labview 7.1?

Thanks
