Most important CoE entries

Table of contents

This chapter describes the CoE objects required for commissioning and user calibration.

Most important CoE entries 1:

Parameterization via the CoE list (CAN over EtherCAT)

The terminal is parameterized via the CoE - Online tab (double-click on the respective object) or via the Process Data tab (allocation of PDOs). Please note the following general CoE information when using/manipulating the CoE parameters:
- Keep a startup list if components have to be replaced
- Differentiation between online/offline dictionary, existence of current XML description
- use “CoE reload” for resetting changes

Objects for the user calibration

User calibration offers the option to process the value of the terminal further after manufacturer calibration. This can relieve the PLC.
