CODESYS Safety for EtherCAT Safety Module SL

The TÜV-certified product allows any CODESYS project to be expanded with an EtherCAT controller with CODESYS EtherCAT Master Stack for the development of safety functions with TÜV-certified safety logic modules from Beckhoff and digital FSoE I/O modules and analog TSC input modules in the EtherCAT network. The expansion with safety-specific editors and configurators is seamlessly integrated into the CODESYS development system and the CODESYS EtherCAT configurator. It enables the cost-effective and scalable implementation of simple safety applications with zero system integration or adaptation effort and low acceptance effort. The product is aimed at users and device manufacturers who do not plan to develop their own safety controller and only require limited safety functionality.

• Safety level up to PL-e according to DIN EN ISO 13849 and up to SIL3 according to IEC 62061/61508, depending on input and output devices and programmed logic.
• Simplified acceptance through Limited Variability Programming (LVL) according to ISO 13849 and IEC 62061.
• Logic modules : EL6900 or EL6910 as EtherCAT terminal (TwinSAFE-Logic), or EK1960 as EtherCAT coupler (TwinSAFE-Compact Controller) from Beckhoff, or EL1918, EL2912, EL2911
• Digital SIL3 I/O modules : FSoE modules (Failsafe over EtherCAT) from any manufacturer installed from EtherCAT description files.
• Analog SIL2 input modules : 10 TSC modules (TwinSAFE SingleChannel) from Beckhoff: EL3124-0090, EL3174-0090 (differential), EL3214-0090 (for resistance sensors), EL3314-0090 (for thermocouple), EL3356-0090 (for load cell/resistance bridge); and encoders EL5001-0090 (SSI), EL5021-0090 (Sin/Cos), EL5032-0090 (EnDat2.2), EL5101-0090 (incremental differential RS422), EL5151-0090 (incremental).

Operating functions and fieldbus configuration on the EtherCAT controller can be changed without affecting the safety functions of the safety logic module.

• Standard signals can be exchanged with the EtherCAT controller: standard input signals for comparison with TSC signals, signals from/to the standard application.
• Multiple safety logic modules possible within an EtherCAT network.
• Groups : Monitoring of several safety areas by a safety logic module supported by structuring the safety application into “groups” of I/O modules and associated logic in an IEC 61131-3 POU in FUP. Each group is started, stopped, diagnosed and error acknowledged individually by the standard application.
• Optional devices : If a safety area is not present in the machine, EL6910 and EK1960 allow the corresponding group to be deactivated via online command without changing the application (permanent, temporary, passivated).
