T总线接口单元及其模块统称为“站”。现场控制站可在GMR系统中用作GMR输入或非GMR输入。它不能用于GMR输出或非投票GMR输入，也不能自动测试。46403总线接口单元模块接线盒模块接线盒带有通信和电源端子的总线接口单元DIN轨道现场控制站接线盒为两个模块提供通用现场接线端子，允许模块类型在同一接线盒上混合。接线板安装在DIN导轨上。DIN导轨是接地系统的组成部分，必须安装在面板上。多达八个现场控制模块（四个接线板）可连接到一个总线接口单元。每个现场控制站可使用一根可选的21英寸（0.53米）电缆（IC670CBL002）。其余的连接必须使用随底座提供的较短连接器进行。总线接口单元总线接口单元提供将模块连接到控制系统所需的扫描、诊断和通信功能。此外，总线接口单元可以为模块提供许多特性，例如故障报告、输出默认值、模拟范围选择和模拟缩放。BIU有四个状态LED和一个用于手持式监视器的连接器。BIU为站内模块提供逻辑电源。必须为设备的现场接线提供外部电源。BIU安装在一个单独的接线板上，所有总线接线都连接到该接线板上。工作站的配置存储在BIU接线盒BIU IC670GBI002F或GBI102A或更高版本中，支持热插拔模块。当电站通电时，可以拆除和更换模块，而不会影响BIU和电站中的其他模块。插入或取出的模块必须关闭单独的电源。热插拔需要目录号后缀为J及以上的模块和接线板IC670CHS101、102或1034。总线接口单元IC670GBI002在24VDC下运行。IC670GBI102在115VAC/125VDC下工作。现场控制模块现场控制模块有多种类型和密度。在GMR系统中，所有模块类型都可以作为非关键模块或单一模块使用。现场控制模拟输入模块可用作TMR。46406状态LED现场控制模拟输入模块现场控制模块是小型坚固的部件，带有坚固的铝外壳。模块约为3.25英寸（8.2厘米）高x 2英寸（5.25厘米）宽。它们是2.90英寸（7.3厘米）深。通过标签的透明中央部分，可以很容易地看到模块LED。模拟输入模块有一个模块状态LED。离散模块还具有单独的电路LED，显示每个输入或输出电路的开/关状态。4-32 Genius®模块冗余灵活三模块冗余（TMR）系统GFT-177A技术产品概述–1998年2月4个接线板接线板是现场控制模块的通用接线基础。它们为用户连接提供模块安装、背板通信和终端。模块拧在接线板上以防振动。可以在不干扰现场布线的情况下将模块从接线板上拆下。
ogether, the Bus Interface Unit and its modules are referred to as an “ Station.” A Field Control Station can be used in a GMR system as GMR inputs or as non-GMR . It can not be used for GMR outputs or non-voted GMR inputs and it cannot be autotested. 46403 Bus Interface Unit Module Terminal Block Modules Terminal Block with Communications and Power Terminals for Bus Interface Unit DIN Rail Field Control Station Terminal Blocks provide universal field wiring terminals for two modules, allowing module types to be mixed on the same Terminal Block. The Terminal block is mounted on a DIN rail. The DIN rail, which is an integral part of the grounding system, must be mounted to a panel. As many as eight Field Control modules (four terminal blocks) can be connected to one Bus Interface Unit. One optional 21-inch (0.53 meter) cable (IC670CBL002) can be used per Field Control station. The remaining connections must be made using the shorter connectors supplied with the bases. Bus Interface Units The Bus Interface Unit provides the scanning, diagnostics, and communications capabilities needed to link the modules to the control system. In addition, the Bus Interface Unit may provide many characteristics for modules, such as fault reporting, output defaults, analog range selection, and analog scaling. The BIU has four status LEDs and a connector for a Handheld Monitor. The BIU provides logic power for the modules in the station. External power must be supplied for field wiring of devices. The BIU mounts on a separate terminal block, to which all of the bus wiring is connected. The configuration of the station is stored in the BIU terminal block BIUs IC670GBI002F or GBI102A or later support Hot Insertion/Removal of modules. Modules can be removed and replaced while station power is applied without affecting the BIU and other modules in the Station. Separate power must be off to the module being inserted or removed. Hot Insertion/Removal requires modules having catalog number suffix J and above and Terminal Blocks IC670CHS101, 102, or 1034. Bus Interface Unit IC670GBI002 operates on 24VDC. IC670GBI102 operates on 115VAC/125VDC. Field Control Modules Field Control modules are available in a wide range of types and densities. All module types may be used in a GMR system as non-critical or simplex . Field Control analog input modules may be used as TMR . 46406 Status LED Field Control Analog Input Module Field Control modules are small rugged components with sturdy aluminum housings. Modules are approximately 3.25 inches (8.2 cm) high x 2 inches (5.25 cm) wide. They are 2.90 inches (7.3 cm) deep Module LEDs are easily visible through the transparent central portion of the label. Analog input modules have one module status LED. Discrete modules also have individual circuit LEDs that show the on/off status of each input or output circuit. 4-32 Genius® Modular Redundancy Flexible Triple Modular Redundant (TMR) System GFT-177A Technical Product Overview – February 1998 4 Terminal Blocks Terminal Blocks are generic wiring bases for Field Control modules. They provide module mounting, backplane communications, and terminals for user connections. Modules screw onto the terminal block for vibration resistance. modules can be removed from the Terminal Block without disturbing field wiring.
