Modbus TCP Client - OPC UA Server Example

ModbusTCPClient_OPCUAServer_simple.py is an example how an adapter between a Modbus TCP Server (Master) and an OPC CLient could be realised with python. Therefore the adapter contains a Modbus TCP Client and a OPC UA Server. For tests of the script a Siemens LOGO with a Modbus TCP Server and a PT100 Temperature Sensor was used. As a OPC UA Client UaExpert was used: https://www.unified-automation.com/de/produkte/entwicklerwerkzeuge/uaexpert.html
