2 Introduction
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)

Distinction between Online and Offline
IO configuration in TwinCAT 9Version: 1.1
3 Distinction between Online and Offline
The distinction between online and offline refers to the existence of the actual I/O environment (drives,
terminals, box modules).
If the configuration is to be prepared in advance of the system configuration as a programming system, e.g.
on a laptop, this is only possible in "Offline configuration" mode. In this case all components have to be
entered manually in the configuration, e.g. based on the electrical design (as described under TwinCAT
configuration setup, manual).
If the designed control system is already connected to the EtherCAT system and all components are
energized and the infrastructure is ready for operation, the TwinCAT configuration can simply be generated
through "scanning" from the runtime system. This is referred to as online configuration.
In any case, during each startup the EtherCAT master checks whether the devices it finds match the
configuration.
To ensure that the latest features/settings of the master can be used, always download the latest ESI file.
Please note the following information.
Installation of the latest ESI-XML device description
The TwinCAT System Manager needs the device description files for the devices to be used in or-
der to generate the configuration in online or offline mode. The device descriptions are contained in
the so-called ESI files (EtherCAT Slave Information) in XML format. These files can be requested
from the respective vendor and are made available for download. The ESI files for Beckhoff Ether-
CAT/EtherCATP devices are available on the Beckhoff website (https://www.beckhoff.de/english/
download/elconfg.htm?id=1983920606140). The ESI files should be stored in the TwinCAT installa-
tion directory (default: C:\TwinCAT\IO\EtherCAT). The files are read (once) when a new System
Manager window is opened. A TwinCAT installation includes the Beckhoff ESI files that were cur-
rent at the time when the TwinCAT build was created. From TwinCAT 2.11 and in TwinCAT 3 the
ESI directory can be updated from the System Manager, if the programming PC is connected to the
internet (TwinCAT → EtherCAT Devices → Update Device Description…)

The manual configuration of an EtherCAT Box/EtherCATP Box in TwinCAT is described in this part of the
documentation.
1. Open the section "I/O" in the "Solution Explorer".
2. Right click on „Devices“ and click on „Add new Item“.
ðA dialog window opens.
3. Select the entry "EtherCAT Master" in the dialog window and click on "OK".
ðAn entry "Device 1 (EtherCAT)" appears.
