Technical Specifications Profibus‑DP field bus interface, internal back‑plane bus interface. Auxiliary DC power supplied by system chassis back‑plane. Operating temperature 0 ℃ to +60 ℃, storage temperature ‑40 ℃ to +85 ℃, relative humidity 5%‑95% non‑condensing. Plug‑in chassis slot mounting form.
Functional Features Realizes protocol conversion between internal control bus and Profibus‑DP fieldbus. Completes data exchange between main controller and Profibus‑DP slave field devices. Supports bus parameter configuration and communication status diagnosis. Provides communication fault alarm signal output.
Application Scenarios Communication spare‑part for GE DCS and PLC automation systems, applied for industrial sites adopting Profibus‑DP fieldbus.
Performance Parameters Stable Profibus‑DP protocol parsing performance, reliable bidirectional data transmission, fast communication fault diagnosis response capability.
Material Composition Flame‑retardant plastic module housing. Multilayer glass‑fiber epoxy printed circuit board. Bus protocol processing circuit, signal isolation components. Gold‑plated back‑plane bus contact connectors. Chassis locking buckle hardware.
Structural Characteristics Standard plug‑in module shape. Rear‑edge gold‑plated connector mates with chassis back‑plane bus. Front‑panel provides Profibus‑DP bus wiring terminals and communication status LED indicators. Module locking buckle fixes unit into chassis slot.
Working Principle Module obtains working power from chassis back‑plane bus. It completes protocol conversion: internal bus data from main controller is converted into Profibus‑DP protocol data and sent to field slave devices. Returning data from Profibus‑DP field bus is converted to internal bus format and transmitted to main control unit. Module monitors bus communication status in real‑time.
Installation Requirements Power‑off chassis system power supply before installation. Insert communication module into designated chassis slot and lock buckle. Complete Profibus‑DP bus wiring and terminal resistor configuration. Restore chassis power supply, configure bus station address and communication parameters, verify data exchange function.
Usage Notes Must match compatible GE host chassis system. Profibus‑DP bus wiring shall follow fieldbus specification, correctly configure bus terminal resistance. Hot‑swap under powered condition is forbidden.
