Implement Modbus RTU/TCP protocol support

Status:

+ Implement Modbus RTU master/TCP client protocol support in CVI

Comments

There are two open-source modbus libraries available that compile fine with CVI. They both are incomplete in different ways but they work. Incidentally, both are named libmodbus.

If this might become reality please consider UDP, too.

We have a Labwindows CVI Application realized with LabWindows V6.0. This application should communicate with a Matrikon server via Modbus TCP protocol.

Is it correct, that therefore we need to implement a Modbus RTU/TCP protocol support in the LabWindows application. We have the Matrikon Server and the

LabWindows application on the same PC. There should be no problem to communicate via Modbus /TCP on the same PC between the LabWindows application

and the Matrikon OPC server?
