groov EPIC becomes a Modbus master/client with a few easy lessons.

With Modbus continuing to be a popular protocol for industrial devices, the chances are pretty good you will need to write a program to communicate with Modbus slave/server devices more than a few times. The groov EPIC controller offers several Modbus communication options, and CODESYS, an IEC 61131-3 compliant development environment, is one of them.

With your PLC programming experience and the Using groov EPIC as a Modbus Master in CODESYS course on OptoU, creating a CODESYS project with Modbus master functions will be a breeze.

The course has step-by-step lessons to help you write your project. The lessons cover:

  • The hardware and software you’ll need
  • Creating a CODESYS project from scratch 
  • Making the groov EPIC a Modbus Master in the CODESYS project
  • Adding a slave to the CODESYS project
  • Downloading and running the CODESYS project

As you work your way through the lessons, the end result is a working project and a method to develop subsequent projects. There’s also a quiz at the end to test your knowledge.

Modbus/TCP is fully integrated with the CODESYS Development System application and Runtime on groov EPIC.

Check out how easy it is to create your own Modbus Master CODESYS project!
