Industrial communication course: Modbus, Profinet, OPC UA, TCP and MQTT
A hands-on networking course for PLC programmers who connect Siemens and CODESYS controllers with drives, robots, scales and IT systems: Modbus RTU and TCP, OPC UA, TCP/UDP, JSON and databases. Profinet is the industrial Ethernet technology Siemens controllers use to exchange data with I/O, drives and other devices, while Modbus and OPC UA connect PLCs from different vendors with each other and with IT systems. In this training you configure each network step by step, assign device names and IP addresses, exchange data between controllers and check the connection with diagnostic tools. It is not an official PI certification class but a practical course for engineers who need working communication on their machines.
Modbus TCP and RTU on Siemens PLCs
Modbus TCP master and server on S7-1200/S7-1500, Modbus RTU master, plus a Lenze frequency inverter controlled over Modbus RTU.
OPC UA and Modbus in CODESYS
Modbus TCP and an OPC UA server in CODESYS, so the same data can be read by SCADA, MES or a Python script.
TCP and UDP with real devices
Open user communication with Siemens PLCs: an ABB robot, a hose crimping machine and other devices that talk over raw TCP sockets.
JSON, SQL and data logging
Building JSON on the PLC, sending it over TCP and logging data to SQL, the basis for Industry 4.0 and IIoT applications.
