1. Overview

In this article, it will be explained how to connect a ctrlX CORE plus X3 with a IndraControl XM21 using the PROFINET connection. This connection can also be done between a ctrlX CORE X3 and an IndraControl XM21. The IndraControl will be first configured using the IndraWorks Engineering program, and the ctrlX CORE will be configured with the CoDeSys Profinet libraries using ctrlX PLC Engineering program.
