CODESYS Safety for EtherCAT Safety Module
Do you need a simple and cost-effective solution for implementing safety functions in accordance with IEC 61508 SIL3 in your application?
Are you already using EtherCAT® with CODESYS-compatible controllers in your automation solution? Then this software product is ideal for you!
Required components
To realize safety applications you need
- The CODESYS Development System (or derivative) as a development platform
- The add-on component CODESYS Safety for EtherCAT Safety Module (installation via the CODESYS Installer or CODESYS Store)
- CODESYS EtherCAT as a fieldbus system
- The right hardware
- CODESYS-compatible controller with activated CODESYS licensing mechanism
- Standard hardware with CODESYS SoftPLC or virtual PLC
- One or more of the supported Beckhoff® EtherCAT safety modules
- EL6900
- EL6910
- EK1960
- EL1918
- EL2911
- EL2912
- Safety I/Os in the EtherCAT network (any manufacturer)

Integrated project planning
Configure the decentralized EtherCAT module directly in the CODESYS Development System as a child of the functional standard controller. Use the integrated FSoE® (FailSafe over EtherCAT) configurator to configure the safety and I/O modules. The safety I/Os are mapped logically into the safety application.
The safety application is programmed in a validated graphical FBD editor. The functions stored in the safety modules, such as emergency stop, safety gate monitoring, two-hand control, etc., are used as library functions.

Data exchange with the functional standard controller is possible via logical global variables. The download of the safety application is secured via an automated diversity compilation check. You can record and document the version status of the safety application using unique CRCs. This saves you, for example, having to re-certify the security application if the functional application changes.

How to get
Use programmable controllers with CODESYS that support the following functions:
CODESYS EtherCAT
Installation and licensing of add-on components
You can find a selection of manufacturers of CODESYS-compatible devices in CODESYS Inside.
Or use a CODESYS SoftPLC from the CODESYS Store on your industrial PC or edge device.
Install the add-on component in the CODESYS Store and license its use.
Integrate a decentralized EtherCAT safety module (see above for supported modules) into your EtherCAT network.
