The IO configuration is the prerequisite for the use of the functions of IO modules in a PLC program. It covers the appending and parameterization of IO modules in TwinCAT.

This quick start guide describes the basic IO configuration in TwinCAT 3 for IO modules of the type:

  • EtherCAT Box (EPxxxx)
  • EtherCAT P Box (EPPxxxx)
