Purpose and area of application

This document is meant for developers who would like to create a backplane or an EJ distribution board upon which standard EtherCAT plug-in modules should be used.

This document gives information about the general design of an EJ distribution board for standard EtherCAT plug-in modules.

When secure EJ modules should be used along with standard EtherCAT plug-in modules please note the additional requirements and notes of the supplementary Design Guide EJ-Backplane for TwinSAFE-modules.
