I have a query with respect to interfacing codesys application using LabVIEW.
I would like to interface with codesys appplication (access to variables in Codesys/models) using LabVIEW. The idea is to test the Codesys application using LabVIEW.
I tried using ActiveX communication, but I am unable to communicate with the codesys application.
Any ideas on this would be really helpful.
What is your target runtime system of Labview?
What is your target runtime system of Codeys?
There are many possible ways to realize this communication:
1, with CODESYS PLC Handler -> need the license from 3s
2. OPC -> need OPC Server license
3.Standard field-bus: MODBUS TCP/Profinet.... -> may need additional hardware or software license.
4. TCP/IP: you need encode and decode the data,this need to developed in low lever
