16电路DC汇点/源块还执行无负载报告，该报告监控单个输出是否存在最小负载。n输出自动测试，确定每个输出是否能达到与其正常状态相反的状态。n输出差异报告，通知每个PLC所有PLC之间不相同的任何输出。差异报告还报告每个PLC的在线/离线状态。Genius输出诊断。在智能开关设计中，16点离散DC汇/源块上的每个点都包含一个电流传感器和一个电压传感器。这提供了关于输出电路和负载状态的数据。在16点块上，离散输出电路由开关设备处的短路传感器保护。如果输出上的瞬时电流超过20安培，输出将在几微秒内关闭。Genius块自动尝试重新启动加载。如果重复尝试失败，模块关闭输出并发送短路诊断信息，该信息由每个PLC CPU接收。如果发生瞬时短路，可通过清除任何PLC中的故障来恢复正常操作。输出自动测试。每个输出可配置为输出自动测试。GMR输出自动测试检查每个离散输出块响应命令输出状态的能力。离散输出自动测试适用于有或无负载监控的开或关输出。输出自动测试不会导致记录虚假故障，也不会影响现场输出设备。Genius块仍然控制物理输出。输出自动测试可被禁止维修。测试使用模块的内置脉冲测试功能。为双工或无CPU冗余配置的单个块不能自动测试，但可以进行脉冲测试。输出差异报告。如果块从PLC接收到相同负载的不同输出，则它们将差异报告给每个PLC，并在故障表中显示差异信息。同时，设置状态位。通过检查该位，应用程序可以自动被提醒在块处的输出差异。输出差异报告还向其他PLC提供每个PLC的在线/离线状态。开关驱动负载电压反馈COMM VLSI IC微处理器输入数据输出数据智能开关驱动和诊断逻辑负载电流反馈I V+V a45495 Genius总线负载Genius输出诊断GFT-177A 3-1 3 GMR系统架构部分T M R*05TM本节旨在概述构成GMR系统的元件，并描述可以设计的不同类型的GMR系统。PLC系统架构GMR CPU位于Series 90-70 PLC的主机架中，紧邻电源右侧。主机架中的其余插槽可用于通信模块、协处理器、Genius总线控制器和基于机架的模块。还可以包括专用模块和定制模块（如以下插槽9所示）。具有六个总线控制器的主机架可以使用Genius块和现场控制模块处理数百个单、双、三离散和模拟。更大的应用可以包括从每个GMR PLC的主机架菊花链连接的多达七个扩展机架。在带有扩展机架的系统中，主机架中必须有一个总线发送器模块，每个扩展机架中必须具有一个总线接收器模块（BRM）。最后一个扩展机架距离主机架最多50英尺（15米）。每个扩展机架最多支持九个模块，其中一个插槽用于BRM。具有三个PLC的GMR系统可以包括多达24个机架，最多93个Genius总线控制器（31个三重组）。一些智能模块必须位于主机架中。GMR总线控制器可以位于主机架或任何扩展机架中。任何机架中都不需要用于“备件”或“热更换”的备用插槽。
The 16-circuit DC Sink/Source blocks also perform No Load reporting, which monitors individual outputs for the presence of a minimum load. n Output Autotest, which determines whether each output can attain the opposite of its normal state. n Output Discrepancy Reporting, which informs each PLC of any output which is not the same among all PLCs. Discrepancy reporting also reports on each PLC’s online/offline status. Genius Output Diagnostics. Each point on a 16-point discrete DC Sink/Source block incorporates a current sensor and a voltage sensor in the smart switch design. This provides data about output circuitry and load state. On 16-point blocks, discrete output circuits are protected by a short circuit sensor at the switching device. If the instantaneous current on an output exceeds 20 Amps, the output turns off within several microseconds. The Genius block automatically tries to restart the load. If repeated tries fail, the block turns the output Off and sends a Short Circuit diagnostic message which is received by each PLC CPU. In the event of a transient short, normal operation can be restored by clearing the fault in any of the PLCs. Output Autotest. Each output can be configured for Output Autotesting. The GMR Output Autotest checks the ability of each discrete output block to respond to the commanded output state. Discrete Output Autotest works on outputs that are either On or Off, with or without load monitoring. Output Autotest does not cause spurious faults to be logged and does not affect field output devices-the Genius blocks still control the physical outputs. Output Autotest can be inhibited for repair. The test uses the blocks’ built-in Pulse Test capability. Single blocks configured for Duplex or No CPU Redundancy cannot be autotested, but can be pulse-tested. Output Discrepancy Reporting. If the blocks receive different outputs for the same load from the PLCs, they report the discrepancy back to each PLC, where a discrepancy message is placed in the Fault Tables. At the same time, a status bit is set. By checking this bit, the application program can automatically be alerted to output discrepancies at the blocks. Output Discrepancy reporting also supplies the online/offline status of each PLC to the other PLCs.

PLC System Architecture The GMR CPU resides in the Main Rack of a Series 90-70 PLC, immediately to the right of the power supply. The rest of the slots in the Main Rack can be used for communication modules, coprocessors, Genius Bus Controllers, and rack–based modules. Special-purpose modules and custom modules (as illustrated below in slot 9) can also be included. A Main Rack with six Bus Controllers can handle hundreds of single, dual, and triple discrete and analog using Genius blocks and Field Control modules. Larger applications can include up to seven Expansion Racks daisy-chained from the Main Rack of each GMR PLC. In a system with Expansion Racks, there must be a Bus Transmitter Module in the Main Rack and a Bus Receiver Module (BRM) in each Expansion Rack. The last Expansion Rack can be up to 50 feet (15 meters) from the Main Rack. Each Expansion Rack supports up to nine modules, with one slot used for a BRM. A GMR system with three PLCs can include up to 24 racks with to 93 Genius Bus Controllers (31 triplicated sets). Some intelligent modules must be located in the Main Rack. GMR Bus Controllers can be located in the Main Rack or in any Expansion Rack. No spare slots are required in any rack for “spares” or “hot replacements”.
