IS215VCMIH2C GE 控制系统中广泛使用的模块

IS215VCMIH2C设计为GE Mark VI涡轮机控制系统中的VME通信卡，对于整个系统的正确功能至关重要。VCMI VME 通信板允许输入/输出 （I/O） 卡与安装在 VME 背板上的其他 I/O 卡、安装在扩展机架上的 I/O 卡、I/O 备份保护模块、三重冗余控制模块以及主处理器或主处理器模块进行通信。

IS215VCMIH2C卡也被广义地称为VME总线主控制器。该PCB连接I/O板和控制器之间的通信。它还充当系统控制网络或IONet的通信接口。

IS215VCMIH2C在其前面板上设有四个端口连接。其中包括一个 RS-232C 串行端口、D 型插头连接器和三个 IONet 10Base2 以太网端口。每个 IONet 连接器都与三个标记为 TX/RX/CD 的 LED 指示灯相关联。该板具有标记为“状态”、“失败”、“运行”和“1、2、4 和 8”的附加 LED 指示灯。前者位于复位开关（按钮）上方，而后者位于串行端口的正下方。

Mark VI系统中的每个控制模块通常包含一个IS215VCMIH2C，这些独特的VCMI卡用于通过控制系统的应用软件与主处理器模块通信执行数据。由于VCMI模块的关键性质，建议在架子上保留额外的备件，以避免机器停机的情况。

The IS215VCMIH2C is designed as a VME communication card in the GE Mark VI turbine control system and is essential for the correct functioning of the entire system. The VCMI VME communication board allows the input/output (I/O) card to communicate with other I/O cards mounted on the VME backplane, expansion rack mounted I/O cards, I/O backup protection module, triple redundancy control module, and the main processor or main processor module.

The IS215VCMIH2C card is also referred to broadly as the VME bus master controller. The PCB connects the communication between the I/O board and the controller. It also acts as a communication interface for the system control network or IONet.

The IS215VCMIH2C has four port connections on its front panel. These include an RS-232C serial port, Type D plug connectors, and three IONet 10Base2 Ethernet ports. Each IONet connector is associated with three LED indicators labeled TX/RX/CD. The board has additional LED indicators labeled "Status," "Failed," "Run," and "1, 2, 4, and 8." The former is located above the reset switch (button), while the latter is located directly below the serial port.

Each control module in a Mark VI system typically contains an IS215VCMIH2C. These unique VCMI cards are used to communicate execution data to the main processor module through the control system's application software. Due to the critical nature of the VCMI module, it is recommended to keep additional spare parts on the shelf to avoid the situation of machine downtime.
