Hîw I read data from PLC SIMATIC S7 200

[Bilchev]

My PLC is SIMATIC S7 224. I want to read analog inputs from PLC addresses AIW0, AIW2 and AIW4 and write to file with VB6.0

Bilchev:

If your PLC is interfaced via serial communication--and I believe that the SIMATIC S7 200 is--then you can use National Instruments' ComponentWorks CWSerial control to interface this PLC. While National Instruments doesn't provide any examples that work with this particular device, you can search our Developer's Zone for general serial examples at

If you already have ComponentWorks installed, then you can check under

Measurement Studio\vb\Samples\Instr

for some examples, also.


Good Luck,
