Advantages of AS-interface
The AS-i protocol simplifies the installation, setup, and maintenance of I/O modules and enhances operation and system reliability:
Simple installation, set-up and maintenance
- Standardised 2-wire flat cable for data and power
- Toolless installation of I/O modules for quick mounting
- Minimal installation errors due to profiled flat cable
- I/O module test without PLC and fieldbus
- Intuitive device replacements thanks to automatic addressing
- Status indications on the slaves
- Flexible topology
Reducing cost and effort
- Standardised sensors / actuators, independent of the controller / fieldbus
- Fewer I/O cards / terminal boxes = smaller cable ducts / control cabinets
- Shorter sensor and actuator cables
Lower calculation risks due to the greatly reduced wiring complexity- Sophisticated diagnostics for fast troubleshooting
- Huge energy saving with fully decentralized pneumatics
Operation and system realiability
Guaranteed transmission time < 10ms with 248 inputs and outputs- Very high EMC immunity in high-level environments
- Symmetry display of the AS-i voltages
- Short circuit and wire break monitoring
For use in harsh industrial environments and in wet areas up to IP69K- For functional safety up to PL e / SIL 3
- ATEX II 3D / 3G
