IS200SCNVG1A机械设备卡件
联机模式提供了完整的CPU通信，允许读取和写入数据。在线维修：在不中断系统操作的情况下进行的维修。在GMR系统中，可以在不断开电源的情况下更换Genius电子模块。此外，90系列机架彼此完全隔离。因此，安装中不需要“备用插槽”和“备用设备”。在线测试：在不绕过系统的情况下完成完整电气测试的集成能力。开放式架构：GMR系统的基于机架的非专有设计。开放式体系结构使得可以在整个GMR系统中包含多种特定于应用程序的模块，包括定制模块。输出自动测试：请参阅自动测试。输出块：一个Genius模块，它将从CPU接收的逻辑电平信号转换为用于控制输出设备的信号。输出设备：由PLC控制的物理设备，如电机起动器、螺线管等。过载和短路检测：用于GMR的Genius模块可以为每个点提供阶跃过载和瞬时短路电子保护。如果发生过载或短路，输出电路会诊断该情况，关闭自身进行保护，然后向CPU中的故障表报告故障。在容错配置中，每条支路都受到单独保护。这防止了在具有单个慢操作保险丝的系统中可能发生的共模故障。并行通信：一种同时在多条导线上传输数据的通信方法。外围设备：PLC外部的设备（例如，个人计算机和打印机），PLC可以与之通信。D-8 Genius®模块冗余灵活三模块冗余（TMR）GFT-177A系统技术产品概述–1998年2月D PLC（可编程逻辑控制器）：一种设计用于工业环境的固态控制设备。PLC从用户提供的控制设备（如开关和传感器）接收信号。它以存储在用户存储器中的应用程序确定的精确模式实现它们。然后，PLC提供用于控制过程或用户提供的设备（例如继电器或电动机起动器）的输出信号。PLC通常在继电器梯形逻辑中编程。PLC故障表：列出PLC故障的故障表。每个故障都按时间、日期和位置进行描述和识别。程序块：结构化编程技术可用于将GMR应用程序的区域划分为功能块。程序块可以从主程序或其他程序块“调用”。程序块可以包含几种可用编程语言之一的逻辑。编程器：用于运行Logicmaster 90编程和组态软件的计算机。R机架：90-70系列PLC的“机箱”，由底板和结构框架组成。模块安装在底板上的配合连接器中，并由机架支撑。RAM：随机存取存储器的缩写。RAM是一种固态存储器，允许随机存储和访问单个位。在Series 90-70 PLC中，RAM存储应用程序文件和相关数据。RAM存储器必须接收恒定的功率以保留其内容。因此，提供备用电池以防止数据丢失。Series 90-70 PLC中使用的备用电池是长寿命锂电池。备用电池安装在CPU模块中。引用：应用程序中用于表示数据类型和位置的逻辑注释。继电器梯形逻辑（RLL）：一种编程语言，使用电气原理图格式的布尔表示来表示应用程序逻辑。参考类型：Series 90-70 PLC的存储器类型定义。例如，%I表示离散输入，%Q表示离散输出。%符号标识后面的字符作为参考。
On-Line mode provides full CPU communications, allowing data to be both read and written. On-Line Repair: A repair made without interrupting system operation. In a GMR system, Genius electronic modules may be replaced without disconnecting the power supply. In addition, Series 90 racks are completely isolated from each other. Therefore, “spare slots” and “spare devices” are not required in the installation. On-Line Testing: An integrated ability to do complete electrical testing without bypassing the system. Open Architecture: The rack-based non-proprietary design of the GMR system. Open architecture makes it possible to include many kinds of application-specific modules, including custom modules, in the overall GMR system. Output Autotest: See Autotest. Output Block: A Genius module that converts logic-level signals received from the CPU to signals for controlling output devices. Output Devices: Physical devices such as motor starters, solenoids, etc., that are controlled by the PLC. Overload and Short circuit detection: The Genius blocks used for GMR can provide stepped overload and instantaneous short circuit electronic protection per point. If an overload or short circuit occurs, an output circuit diagnoses the condition, turns itself off for protection, then reports the fault to the Fault Tables in the CPUs. In fault-tolerant configurations, each leg is individually protected. This prevents the type of common-mode failure that can occur in systems with single slow-operating fuses. P Parallel Communications: A method of communications in which data is transferred on several wires simultaneously. Peripheral Equipment: Devices external to the PLC (for example, personal computers and printers) with which the PLC can communicate. D-8 Genius® Modular Redundancy Flexible Triple Modular Redundant (TMR) GFT-177A System Technical Product Overview – February 1998 D PLC (Programmable Logic Controller): A solid–state control device designed to operate in an industrial environment. The PLC receives signals from user-supplied control devices, such as switches and sensors. It implements them in a precise pattern determined by application programs stored in user memory. The PLC then provides output signals for control of processes or user-supplied devices such as relays or motor starters. PLCs are usually programmed in relay ladder logic. PLC Fault Table: A fault table listing PLC faults. Each fault is described and identified by time, date, and location. Program Block: Structured programming techniques can be used to separate areas of a GMR application program into functional blocks. Program blocks can be “called” from the main program or from other program blocks. Program blocks may contain logic in one of several available programming languages. Programmer: The computer used to run the Logicmaster 90 programming and configuration software. R Rack: The “chassis” of the Series 90-70 PLC, consisting of a baseplate and structural frame. Modules install in mating connectors on the baseplate and are supported by the rack frame. RAM: An acronym for Random Access Memory. RAM is a solid-state memory that allows individual bits to be stored and accessed at random. In the Series 90-70 PLC, RAM stores the application program files and related data. RAM memory must receive constant power to retain its contents. Therefore, a backup battery is provided to prevent data loss. The backup battery used in the Series 90-70 PLC is a long–life lithium battery. The backup battery is mounted in the CPU module. References: The logical annotation used in an application program for representing data types and locations. Relay Ladder Logic (RLL): A programming language that uses a boolean representation in electrical schematic format to represent application program logic. Reference Type: Memory type definitions for the Series 90-70 PLC. For example, %I represents discrete inputs and %Q represents discrete outputs. The % symbol identifies the characters that follow it as a reference.
