: The EL6900 is programmed using the TwinCAT 3 Safety Editor or TwinCAT 2.
The EL6900 is a TwinSAFE Logic Terminal from Beckhoff, designed as a dedicated safety controller for safety-oriented applications. Here's a detailed overview:
Functionality: It processes safe input signals and generates safe output signals using certified function blocks. These range from simple Boolean functions (like AND, OR) to more complex ones for muting safety functions.
Connections: It supports up to 128 safe communication devices via FSoE (Fail Safe over EtherCAT).
Programming: The EL6900 is programmed using the TwinCAT 3 Safety Editor or TwinCAT 2.
Backup and Restore: It includes a feature for easy replacement of the safety controller during servicing.
Technical Specifications:
Protocol: TwinSAFE/Safety over EtherCAT
Cycle Time: Approximately 500 µs (depending on project size)
Safety Standards: Complies with DIN EN ISO 13849-1:2008 (Cat. 4, PL e) and EN 61508:2010 (SIL 3)
