AS-i Network Architecture
The 6GK1243-3SA00 supports the AS-i master-slave protocol for simple field device integration. It automatically detects and configures connected slave devices upon power-up. This plug-and-play functionality minimizes setup time.
Integrated Power Supply and Cabling
The module provides the necessary power for the entire AS-i network. Standard two-wire cables deliver both communication signals and energy to all slaves. This hybrid approach reduces installation costs.
Application and System Integration
This CP suits low-cost I/O applications requiring minimal wiring. It accepts digital sensors, actuators, and analog modules within the AS-i network. Consequently, maintenance engineers can quickly expand or modify field devices.
