No.: 51-52-25-63 Release: E Last Revision Date: 1/01 Notices and Trademarks Copyright 2001 by Honeywell Release E January, 2001 Overview UMC800 Overview Introduction The Universal Multi-loop Controller (UMC800) is a modular controller (see Figure 1) designed to address the analog and digital control requirements of small unit processes. With up to 16 analog control loops, four set point programmers, a set point scheduler, and an extensive assortment of analog and digital control algorithms, the UMC800 is an ideal control solution for furnaces, environmental chambers, ovens, reactors, cookers, freeze dryers, extruders, small boilers, and other processes with similar control requirements. Accommodating up to 64 universal analog inputs, 16 analog outputs, or 96 digital inputs or outputs, the UMC800 provides the appropriate balance of input and output hardware for these smaller unit processes. Split architecture The UMC800 uses a split architecture that separates the control functions from the operator interface functions to provide greater installation flexibility. Controller The controller is composed of a CPU with two serial communication ports, power supply, and a backplane assembly. It incorporates a card rack that is capable of supporting up to 16 input and output modules that can be mixed to satisfy the hardware requirements of a specific application. Modules are available in ten different configurations to support both analog and digital inputs and outputs of various types and signal levels. Each module has a removable terminal block accepting #16 AWG wire. An optional RS485 serial communication card that supports both slave data exchanges with a host PC for centralized operation and data management and/or communications via a Modbus RTU master to other Honeywell or 3rd party compatible products. Operator interface The operator interface uses a color graphic LCD display to provide a variety of screen presentations for viewing control loops, setpoint programs, and other analog and digital status. Modification and customization of the operator interface are performed using UMC800 Control Builder software. With the software, data points can be identified (tagged) using eight character names. Once named, these data points may be accessed by the operator interface using a standard set of display formats and a predefined menu hierarchy. Customized display access and the assignment of selected display screens to keyboard buttons may be developed using Control Builder software. Selected screens such as bar graphs, trends, and overview displays will require the user to specify the individual data points to be represented on the screen. A menu selection allows the user to select from English, French, Italian, Spanish or German languages. Control Builder A separate “Control Builder” configuration software program is used for UMC800 Controller and Operator Interface configuration and operates on a Windows 95, 98 or Windows NT-based PC. The software program uses graphic symbols and line drawing connections to create custom control strategies. All configuration is performed off-line (computer disconnected from the controller and operator interface). The configuration is downloaded in a separate operation as a complete file through a dedicated RS-232 communication port on the controller. Once a configuration is installed into the controller and operator interface, the Control Builder software may be used to monitor areas of the configuration to verify proper operation. Menus are provided in the software to allow selection of screens for the operator interface and to customize screen access methods and operator keys. Completed configurations are loaded into the control system using a dedicated communication port in the controller or, optionally, via floppy disk from the operator interface. Loop control The UMC800 supports up to sixteen control loops with PID, ON/OFF, Carbon Potential, or 3 Position Step control action. Control loops may be configured to operate independently or in cascade. Operator entered setpoints may be limited by independent high and low limit values and setpoint rate of change limits are available to protect critical products during process changes. When Feedforward operation is applied, a separate Feedforward gain adjustment is available to tune the loop for the appropriate Feedforward response. When Ratio control is applied, a ratio and bias adjustment are provided. When used with the supplementary loop control blocks, digital inputs may be used to set control mode, select the setpoint source, change control action, and perform other discrete actions. A status block provides digital outputs to facilitate integrating loop operation with other functions in the controller. When configured for dual output (heat/cool), each output may be directed to different output types, for example: current, time proportioning, etc. Two sets of tuning constants for heating and cooling are also provided. Accutune Honeywells Accutune IITM automatic tuning algorithm with Fuzzy Logic Overshoot Suppression is available for each loop of the controller. Initiated on command from the operator interface or through a digital input to the loop, this easy to operate feature optimizes control performance with a minimum of process disturbance. Logic The controller offers up to 96 digital inputs or outputs and uses digital function blocks to perform Boolean logic operations and sequences. The digital function blocks may be programmed to operate on a fixed 100- millisecond update rate or on the slower analog measurement scan rate as determined during configuration. Alarms Alarm monitoring may be assigned to the digital status of analog alarm blocks, or other digital block status. Each PID loop also provides up to four alarms of various types. Alarm flexibility is also expanded using the analog alarm block, which allows selective set-up of alarm hysteresis, deviation alarms, on delay, selective latching, and a disable input to control when the alarm is active. Active alarm indication is provided on all operator displays and alarm group displays are provided to view and acknowledge active alarms. An alarm detail display is provided for each alarm point which indicates the time and data of last alarm occurrence and offers 40 characters of user specified text for alarm actions or notes. Up to 120 alarms may be configured and applied to loop alarms or digital tags. Function block configuration The UMC800 uses function block configuration architecture to develop control strategies for both analog and digital operations. A function block may represent a physical input or output, several physical inputs or outputs, an internal calculation, or an internal function such as a PID algorithm. All configuration is done using the Control Builder software. A summary of the assortment of greater than 75 standard UMC800 function block algorithm types follows. Typically, a function block algorithm type may be used any number of times up to the limit of 250 blocks. Some of those with specific limits are: PID and ON/OFF control loops and associated support blocks eight or sixteen maximum Setpoint programmer blocks and associated support blocksfour maximum Setpoint Scheduler blocks and associated support blocksone maximum Time proportioning output blockssixteen maximum Pushbutton blocksfour maximum 4 Selector Switch blocksfour maximum Modbus Slave blockssixteen maximum Digital I/O and digital function blocks are scanned and executed every 100 milliseconds. Analog I/O and analog function blocks are processed at a rate based on the quantity of I/O and the number of function blocks contained in the controller. Operator interface displays configuration Modification and customization of the operator interface are performed using UMC800 Control Builder software. With the software, data points can be identified (tagged) using eight character names. Once named, these signal tags may be accessed by the operator interface using a standard set of display formats and a predefined menu hierarchy. Customized display access and the assignment of selected display screens to keyboard buttons may be developed using “Control Builder” software. Selected screens such as bar graphs, trends, pushbutton actions and overview displays will require the user to specify the individual signal tags to be represented on the screen. Setpoint programming Up to four independent, setpoint-programming blocks may be configured in the controller using the “Control Builder” software. A single program (profile) may be from 2 to 50 segments in length. Up to 70 programs are stored in the controllers memory. Each segment of the program may be a ramp or a soak except the last step that must be a soak. In addition to the main ramp and soak output value, a second analog value (Aux. Output) is available for each step of the program. This output is a fixed soak value that may be used to provide a setpoint value for a secondary control loop in the process. An example would be a ramp and soak temperature program combined with pressure setpoints for each step of the program. Setpoint scheduler A suite of Setpoint Scheduler blocks may be configured for multi-setpoint control. The suite is comprised of a Master block, Auxiliary Setpoint block, Auxiliary Event block, State Switch Block, and State Flags block. (See Figure 46.) The Master block supports up to 8 ramp or soak outputs operating on a common time base. It accepts one PV for each setpoint and is shown on the Operator Interface scheduler screen. Setpoint guarantee is provided for the master (SPS) block setpoints with a single symmetrical value for each setpoint output. You can assign a failsafe value for each setpoint. The Auxiliary block supports up to 8 soak only outputs. The Event block supports up to 16 event outputs. A single schedule may be up to 50 segments in length and includes auxiliary block data. Up to 10 schedules may be stored in the controllers memory. Setpoint Schedules offer the same operating modes and digital controls as setpoint programs. On-line editing of a running schedule is supported through dedicated operator interface displays 譯文： UMC800 Control Builder 使用指南 編號： 51 52 25 63 版本： E 最后修正時間為： 1/01 警告和商標 2001 年版權為霍尼韋爾所有 2001 年一月版本為 E 概述 UMC800 的概述 緒論 萬能控制器（ UMC800）是一個被設計用于模擬數(shù)字控制小單位程序的需求的一種標準組件的控制器（ 如圖 1）。一個控制器最多能夠安裝 16 個模擬控制回路， 1 個 CPU 模板， 4 個設定點程序、并具有豐富的模擬和數(shù)字控制算法，UMC800 是一個理想的工業(yè)爐控制方案， 特別適合于工業(yè)爐、環(huán)保設備、化學反應器、加熱爐、鍋爐、空壓機、冷凍機、鼓風機、冷凍干燥器等 工藝設備 。 UMC800 為小型過程提供了輸出和輸入的 可擴展性，適應于 64 個 模擬量輸入，和 16 個模擬量輸出，或 96 個 I/O 輸入或輸 出。 UMC800 采用模塊式結構，其控制器模件和操作模板相分離，使其具有較大的安裝靈活性。 控制器 控制器由一個帶有兩個串行通信接 口、電源和一個集成模板的 CPU 構成。它最多能夠安裝 16 個輸入和輸出模板的插卡式機架，并能夠被組合去滿足一個特殊的應用程序的硬件需求。 模塊可用 10 個不同結構去支持不同型號和信號水平的模擬和數(shù)字的輸入和輸出。每個模塊都有一個可移動的接線板提供 16AWG 線的端口。 一個可行性的 RS-485 轉換器， 可直接同 PC 機相連，由于采用了 Modbus通訊協(xié)議，所以還可與網絡上的其它設備進行數(shù)據(jù)交換，完成監(jiān)控與控制功能，實現(xiàn)從局部控制到整體的協(xié)調與數(shù)據(jù)共享。 操作員界面 操作員接口采用 LCD 彩色顯示屏， 可用于觀查和監(jiān)控控制 回路、設定點程序和其它模擬與數(shù)字功能。操作員接口可完成的修改和定制進行使用 UMC800控制器軟件。 以軟件 , 數(shù)據(jù)點可接受 8個輸入字符名字。 一旦命名 , 這些數(shù)據(jù)點也許由操作員接口獲取使用標準套顯示形式和一個被預定義的菜單階層。 定制的顯示通入和選擇的顯示屏的任務操作按鈕也許被開發(fā)使用控制器軟件。 選擇的屏幕 譬如條線圖 , 趨勢 , 并且概要顯示將要求用戶指定各自的數(shù)據(jù)點代表在屏幕 菜單選擇允許用戶挑選英語 , 法語 , 意大利語 , 西班牙語或德語語言 組態(tài)軟件 一個分開的“控制組態(tài)”配置軟件程序被使用為 UMC800 控制器和操作員接口配置在 Windows 95, 98 or Windows NT-based PC 上打開，人機程序使用圖表標志和圖線描述連接具有創(chuàng)造性。 所有配置是執(zhí)行的 離線的 (計算機被分開從控制器和操作員接口 ) 配置被下載在分開的操作如同一個完全文件通過 RS-232 通信端口接到控制器。一旦配置被安裝入控制器和操作員接口 , 控制組態(tài)軟件就可能被用來對完成監(jiān)控與控制功能的操作。 菜單被提供在軟件允許屏幕的選擇為操作員接口和定做屏幕存取方式和操作員鑰匙。 完整的配置被裝載入控制系統(tǒng)中使用一個通信端口在 控制器或任意地通過軟盤連接到操作員接口。 控制回路 UMC800 可完成最多 16 個 PID 式 ON/OFF 的控制回路， C， 三位步進控制。每個 控制回路都可能提供自整定。 操作員被輸入的設定點程序也許由獨立限制到處極限值和設定點程序變化率極限有時間保護重要產品在處理變動期間。 當應用比率控制時 , 比率和偏壓調整被提供。 當使用以補充圈控制塊 , 數(shù)字輸入也許被使用設置控制方式 , 選擇設定點程序來源 , 改變控制活動 , 并且進行其它分離行動。 狀態(tài)塊提供數(shù)字輸出促進集成操作以其它作用在控制器。 當配置為雙重產品 (熱 /冷 ), 各產品有控制輸出類型 , 例如 : 電流 , 時間成比例等。 二套定調的常數(shù)為熱化和冷卻并且被提供。 精度 霍尼韋爾的集成模塊 都提供自整定，模糊邏輯抑制超調等各種算法。初始命令從操作員接口或通過數(shù)字輸入模塊進入，這種容易操作的特點優(yōu)先控制表現(xiàn)以處理干擾的極小值。 邏輯性 控制器提供 96 個數(shù)字輸入或輸出并使用數(shù)字式的功能塊來執(zhí)行布爾邏輯操作和排列。數(shù)字式功能塊可以被編程操作固定的 100 毫秒更新率或在更加緩慢的模式測量掃描速率依照配置期間而被確定。 報警 報警監(jiān)控可被分配到報警模式塊的數(shù)字式模塊，或其他數(shù)字式模塊。 每個PID 中可以提供各種各樣的類型的四個報警。報警的靈活性并且被擴展應用到報警功能塊中，允許報警滯后作用是有選擇性設定的，偏差報警，延遲報警，有選擇性鎖上，并且功能失效時，輸入控制報警是有效的。 有效的報警表示被提供
