Seminar ID 76109
Identifier PRG3XLCOD3
Course type Classroom Based Training
Duration 3 Days
Target audience Developers
Price 2070 €


The course explains the programming of the ESX.3xl controller with CODESYS V3 including the STW-specific software, plug-ins, libraries and tools.

The course is intended for developers, who will program own applications for the ESX.3xl.

The theoretical course content will be deepened with programming examples from practice.


The participant

  • Knows hard- and software requirements for programming the ESX.3xl
  • Knows the STW technical documentation and is able to use it for target-oriented research
  • Is able to program own applications with CODESYS and the STW software package
  • Is able to upload software on the ESX.3xl, change parameters and monitor the controller


Basic programming knowledge, ideally with CODESYS V3, at least knowledge of programming electronic controllers.
