For your safety 2.3.3 After operation De-energize and switch off components before working on them Check all safety-relevant equipment for functionality before working on the TwinSAFE component. Secure the working environment. Secure the machine or plant against being inadvertently started up. Observe the chapter Decommissioning [} 48].
Extension of the Beckhoff I/O system with safety functions The TwinSAFE products from Beckhoff enable convenient expansion of the Beckhoff I/O system with safety components, and integration of all the cabling for the safety circuit within the existing fieldbus cable. Safe signals can be mixed with standard signals as required.
The EtherCAT plug-in modules and the plug level for sensors and actuators can be placed flexibly on the signal distribution board. Signal distribution boards can be user-developed or provided as custom solutions by Beckhoff Automation GmbH & Co. KG. Fig. 1: EtherCAT plug-in module system (EJ) Version: 2.0.0...
TwinSAFE EJ modules may only be used for the purposes described below! The TwinSAFE EJ modules expand the application range of the Beckhoff EtherCAT system by functions that enable it to be used in the field of machine safety as well. The TwinSAFE EJ modules are designed for machine safety functions and directly associated to industrial automation tasks.

General operation / function Installation 5.2.1 Safety instructions Before installing and commissioning the TwinSAFE components please read the safety instructions in the foreword of this documentation. 5.2.2 Transport / storage Use the original packaging in which the components were delivered for transporting and storing the TwinSAFE components.
General operation / function 5.2.3.2 Installation position and minimum distances For the prescribed installation position the backplane is mounted horizontally (EJ plug connector vertical), and the connection surfaces of the EJ modules face forward (see diagram below). The EJ modules are ventilated from below, which enables optimum cooling of the electronics through convection.
General operation / function 5.2.4 Electrical installation WARNING Risk of injury! Bring the bus system into a safe, de-energized state before starting installation, disassembly or wiring of the devices! 5.2.4.1 Connections between EJ modules The electrical connections between the EJ Bus Coupler and EJ modules are realized automatically by plugging the components into the EJ backplane.
General operation / function Digital input 5.3.1 Parameterization Two indices are provided under the safety parameters for the parameterization of the inputs. These are the general settings for the test pulse outputs and the channel-specific settings for the input filter. In the TwinSAFE EJ modules an input module consists of two channels.
General operation / function 5.3.2 Characteristic curve of the inputs The characteristic curve of the inputs is similar to type 3 according to EN 61131-2. Fig. 4: Characteristic curve of the inputs Digital output NOTE protected wiring If the wiring of the outputs or the connected actuators leaves the control cabinet, the user must ensure that the wiring is protected.
General operation / function 5.4.1 Parameterization The outputs are parameterized via the Safety Parameters tab of the alias devices. A TwinSAFE EJ output module consists of four channels. Fig. 5: Digital output –safety parameters Index Name Default value / Description unit 80x0:01 ModuloDiagTestPulse 0x00 / integer Modulo value for the frequency of the generation of...
