IS200VCMIH2C The main core functions are as follows: Managing data arbitration and timing scheduling for all boards on the VME backplane (CPU, I/O cards, speed measurement cards, protection cards), serving as the data exchange hub for the entire VME rack.

Equipped with 3 IONet 10BASE2 (coaxial BNC) Ethernet ports for real-time turbine control networking between controllers, between controllers and remote I/O units, and between controllers and HMIs;

The front panel features a built-in RS232 debug port, supporting local program download, fault diagnosis, and firmware upgrades;

The Mark VI standard triple-redundant control system has three racks (A/B/C), each requiring a VCMI for triple redundancy data synchronization;

The front panel includes Run/Fail/IONet link status LEDs and a hardware reset button.

In short, the VCMI is an essential bus master for the rack; without it, the entire system cannot function.

Specific parameters are as follows:

Processor: TI TMS320C32 32-bit floating-point DSP

Memory: 32KB DPRAM dual-port RAM (VME backplane shared cache)

Front panel I/O: 3×BNC IONet + 1×DB9 RS232

Backplane connectors: P1+P2 standard VME64 connectors

Power supply: Backplane + 5V power supply, typical power consumption ≈ 6W

Operating temperature: -20℃ ~ +60℃, with tri-proof coating, suitable for harsh power plant environments
