1. Full Model & Model Breakdown

Full Model Name: GE VMICLB-5565 Reflective Memory Node Card

• GE: Brand (Originally VMIC, later acquired by GE, now under Emerson)
• VMIC: Original product line identifier of VME Microsystems International Corporation
• LB: Form factor & bus specification code
• 5565: Series number, the classic 5565 reflective memory card series
• Reflective Memory Node Card: Shared-memory real-time communication board

VMICLB-5565 is a VME bus reflective memory board in the VMIC 5565 series, commonly matched with GE turbine control systems and real-time simulation systems.

2. Main Functions

1. High-speed real-time communication board adopting Reflective Memory technology.
2. Creates a shared memory space within a multi-node network. Data written by any node will be synchronously updated to all other network nodes with ultra-low latency.
3. Delivers deterministic data transmission with minimal latency, independent of delays from the TCP/IP protocol stack of operating systems.
4. Supports hardware interrupts to notify the local CPU automatically once data is updated.
5. Equipped with VME bus interface for installation in VME industrial chassis to realize high-speed data exchange among multiple controllers.
6. Supports optical fiber transmission and features strong resistance to electromagnetic interference.
7. Enables clock synchronization and fast exchange of process data and control commands among multiple devices.

3. Applications

1. Compatible with GE Mark V / Mark VI / Mark VIe gas turbine and steam turbine control systems.
2. Deployed in power stations, turbine unit control, industrial real-time simulation and Hardware-in-the-Loop (HIL) testing.
3. Used in distributed real-time control systems with multiple controllers requiring hard real-time performance.
4. Applied to high-reliability real-time data exchange scenarios in aerospace, defense, rail transit and energy industries.
5. Serves as spare part for high-speed interconnection between control systems to rapidly share interlock signals and operating parameters.
6. Suitable for critical industrial control occasions where ordinary Ethernet fails to meet microsecond-level low-latency communication requirements.
