Safe Mathematical Functions with SARC
Tailored funcional safety
Programmable safety PLC for EtherCAT networks, designed for applications requiring high flexibility and precision. Featuring a certified SARC library and FSoE Master functionality, it enables secure and customized integration of drives, I/O modules, and safety devices.
Processor and memory
- Safety control compliant up to PL e (EN ISO 13849-1) or SIL3 (IEC 61508)
- Safe logic management for input, output, status, and enable signals
- Integrated Fast Channel with guaranteed 4 ms processing time
- Internal memory for safety parameters
Common communications
- Up to 14 digital inputs
- Up to 5 shutdown channels
- Up to 20 I/O (SCU-2-EC version, see additional communications)
- 2 relay outputs
- Supports connection of up to 32 FSoE slave modules
- Secure communication (SMMC: Safe Master-Master Communication) for data exchange between FSoE Masters via EAP
- Adaptable profiles for various inverter types/manufacturers to enable process data exchange and centralized parameter configuration
Additional communications
SCU-1-EC | Standard Configuration
SCU-1-EC/NM | Standard Configuration + Integrated Communication Interface (/NM):
- Safe kinematic module for up to 6/12 axes with spatial mapping of speed and position
- Additional fieldbus interface and FSoE slave/PROFIsafe stack for secure connection to higher-level control systems
SCU-2-EC | Standard Configuration + Up to 20 digital outputs for I/O modules
SCU-2-EC/NM | Standard Configuration + Integrated Communication Interface (/NM)
Expandability and diagnostics
- Drive monitoring in centralized or decentralized mode
- Complete set for monitoring drives on single or calculated axes (based on kinematic functions)
- Time-deterministic data exchange and centralized parameter configuration adaptable to converters/manufacturers
- Coded status display via front-facing 7-segment display and status LEDs
- Multifunction button (Quit, Start, Reset) accessible from the front panel
- Easy drive implementation via Safe Drive Profile
Programming
