Main Functions

System‑core communication hub: Acts as the key bridge between VME backplane bus, main controller processors and distributed remote I/O racks. It manages high‑speed real‑time data exchange for the Unit Data Highway (UDH) within Mark VI/VIe system.More products: www.plcva.com
IONet fiber‑optic network management: Provides three independent IONet Ethernet ports for TMR redundant communication. Transmits control setpoints to remote I/O modules and collects field feedback signals back to main controllers with low deterministic latency.\

Software‑Implemented Fault Tolerance (SIFT) voting: Supports triple‑modular‑redundant signal voting logic. It filters abnormal data from any single faulty channel to avoid single‑point communication failures and guarantee turbine control reliability.
VME bus master control: Performs bus arbitration, data buffering and synchronization for other VME‑format boards inside the control cabinet, ensuring orderly interaction among processor boards, I/O terminal boards and auxiliary modules.
Local serial debugging interface: Equipped with RS‑232 diagnostic port for on‑site firmware downloading, parameter configuration, troubleshooting and maintenance work.
Comprehensive hardware status indication: Multiple LED indicators display run status, fault alarm and IONet port traffic, helping maintenance engineers quickly locate communication link faults or board‑level failures.
On‑board self‑diagnosis: Continuously monitors communication link health, bus error and internal hardware status; reports fault information to system event log for predictive maintenance.
Hot‑swap compatible: Designed for rack‑mount installation inside Mark VI / Mark VIe cabinets; supports hot‑swap replacement under permitted operating conditions to shorten system downtime.

General Electric IS200VCMIH2BEE VME Communication Interface Board

Compatible control system: GE Speedtronic Mark VI and Mark VIe turbine control & protection platforms.
Target equipment: Heavy‑duty gas turbines, steam turbines, combined‑cycle power units, large‑industrial compressors and generator sets.

General Electric IS200VCMIH2BEE VME Communication Interface Board

Industry sectors: Thermal power plants, combined‑cycle power stations, oil‑gas compressor stations, petrochemical complex facilities and other critical energy‑generation sites.
Purpose: Realizes high‑reliability real‑time communication between main control processors and distributed I/O subsystems. Delivers critical turbine‑control commands and field measurement data. Guarantees stable operation of TMR protection‑control loops for rotating machinery. It serves as essential spare‑part for existing running Mark VI/VIe installations.
