Chapter 11 – Getting Started With Profinet

This chapter describes how to control the Helios using the Profinet protocol, and how to read data from the Helios.
Examples are shown using the tool “ProfinetCommander” to provide examples.

The tool “ProfinetCommander” presents the data from the Helios like this:

The status register (2 bytes) and results (multiple bytes) are presented in the “Input” section, and the “Output” section
shows the command byte that will be sent to the Helios:

To send a command, click on the value shown in the “Output” section, and an edit box appears:
