Core Function

PPRF PROFIBUS DP master gateway I/O pack for Mark VIe turbine control system. It acts as protocol conversion bridge between Mark VIe IONet network and PROFIBUS‑DP field bus. It realizes bidirectional real‑time data exchange between main controller and PROFIBUS slave devices such as drives, remote I/O and on‑site instruments. The dedicated communication chip undertakes protocol processing, reducing main controller computing load. Dual IONet redundant network improves communication reliability. It supports simplex and TMR triple‑modular redundant turbine configuration, realizes seamless integration of third‑party field‑bus equipment into turbine control system.

Product Details

The IS220PPRFH1B with part number 336A5026ADP2 belongs to PPRF series PROFIBUS master gateway module for GE Speedtronic Mark VIe control system.

This plug‑in distributed I/O pack is equipped with Hilscher COM‑C dedicated fieldbus processor, independently completes PROFIBUS‑DP master‑station protocol processing without occupying main controller resources. It communicates with Mark VIe controller via dual‑channel redundant IONet Ethernet, collects data from PROFIBUS DP slave stations and transmits control commands downwards. It supports baud rate auto‑adaptation, and can access up to 125 slave devices. Built‑in bus diagnosis function monitors fieldbus signal quality, short‑circuit and station offline status, and uploads fault information to ToolboxST software. Hot‑swap design allows module replacement without shutting down control rack. Front‑panel LED indicators clearly display power supply, network link and PROFIBUS bus running status for convenient on‑site inspection and troubleshooting. Conformal coated circuit board improves anti‑vibration, moisture‑proof and anti‑electromagnetic‑interference performance, adapts to harsh working environment of power‑plant turbine cabinet. Widely deployed in gas‑steam turbine and combined‑cycle unit control cabinets.

It belongs to critical field‑bus gateway spare‑part for Mark VIe turbine control system, widely used in overhaul and renovation projects of power generation units.

It is important spare hardware for PROFIBUS fieldbus loop debugging and defective IS220PPRFH1B module replacement.
