System Architecture & Signal Flow
The 3402091100 module integrates into the EXTT 640-series backplane via the proprietary high-speed bus connector. In a typical architecture:
- CPU/Controller Layer: EXTT 640-series CPU module issues scan-cycle commands.
- Module Layer: 3402091100 receives I/O data and executes local logic or signal conditioning.
- Field Layer: Sensors, actuators, and field devices connect via terminal blocks or sub-bus modules.
- Communication Layer: Data propagates upstream to HMI/SCADA via EXTT-native or standard industrial protocols (Modbus, PROFIBUS, Ethernet/IP — confirm with system configuration).
The -1EA variant occupies one slot; the -2EA variant occupies two adjacent slots and doubles the I/O capacity within the same logical address space.
