Beckhoff EL6900 EtherCAT Terminal communication interface, TwinSAFE Logic. The EL6900 TwinSAFE component is a dedicated safety controller. It is used for the realization of safety-oriented applications on the basis of Boolean values. For this purpose, certified function blocks are available that enable the processing of safe input signals and the generation of safe output signals. The functionality of the function blocks ranges from simple Boolean functions such as AND and OR to complex function blocks for muting the safety function.
With the backup and restore function, the EL6900 additionally offers a simple way to exchange a safety controller in case of service.
The EL6900 can safely exchange data via FSoE with up to 128 safe communication devices.
The EL6900 is programmed with the TwinCAT 3 Safety Editor or with TwinCAT 2.
