digital output are identical. c) 进行改变设定值、控制模式和输出试验。 Testing of changing set data, control module and output. d) 对数字或程序回路的组画面，通过改变其状态，观察块的颜色或状态显示信息的变化应符合组态要求。 For group—screen of digital or procedure loop, color of observation block or change of indication result shall meet function requirement by changing its status. e) 确认对可选择功能 Selection function: 高低限报警、偏差报警、输出限制、调整参数、电源故障重新启动模式、串级或前馈回路信息、滤波器参数以及其它与回路或数字程序有关的信息的组态。 Functioning of high or low limit alarm, deviation alarm, output restict, modulating parameter, restarting pattern of power default, loop of series or pre—feedback, filter para. And other messages related to loop or number procedure. 4) 回路画面测试 Loop screen testing: a) 键入位号，调出回路画面，确认回路类型组态正确。 In putting tag No. and finding loop screen. Making sure function of loop type is right. b) 确认测量值、设定值、输出等正确组态。 Making sure correct functions such as measured data, set date , and output. c) 进行改变设定值、控制模式和输出的试验。 DCS系统调试方案 DCS Test Scheme Testing of changing specified data, control moclule and output. d) 确认可选择的功能已按设计正确组态。 Ensure Selection function: e) 用工程师键盘在此画面上进行修改组态参数，如在线改变调整参数、组态信息的定义、算法选择等试验。 Modifying function parameter using engineer keyboard on the screen. Such as, changing regulation para, on line, concept of function, selection of caculation method. 5) 历史趋势画面测试 Testing of history trend screen: a) 确认该画面已按组态数据表组态。 Afirming screen functioned on basis of function data. b) 时间 基准变更试验（可从 30分钟到 12小时变更） Altering test of time basis (from 30 minutes to 12 hours) c) 通过输入信号，观察画面能按实时信息自动更新，对设计指定的变量进行历史趋势系统储存时间检查，应能保存 2030天。 Observe screen can renew automaticly according to actual information through inputting signal. Storage time of specified variability history trend shall be checked and preserved 2030days. 6) 报警汇总画面测试 Testing of alarm collective screen: a) 检查报警画面应按各报警发生时间先后顺序排列，且报警画面一旦被调用，即在画面顶部显示最新的报警。 Inspecting alarm screen according to alarming time sequence. If selected and used, latest alarm shall be showed at the top of screen. b) 确认每个报警的操作组号、说明文字、优先级别等正确，且不同优先级别的报警的声光区分正确。 Making sure operation No, instruction words, priority level is correct. Sound and light classification of different priority level alarm is true. c) 确认任一操作台上消声操作均能关闭所有的蜂鸣器。 DCS系统调试方案 DCS Test Scheme Affirming sound—absorption plant of every operation table can close all sounders. 7) 系统状态画面测试 Testing of system status screen: a) 调出系统状态画面，检查连接在通讯系统上的各节点已正确组态。 Finding system status screen. Checking all joints connecting with munication system have been correctly functioned. b) 当其中任一节点发生故障时，应能发出报警信号。 Alarming if each joint is wrong. 操作键盘功能试验 Keyboard Function testing: 1) 确认由操作员直接操作的功能键操作正常，能调出各种显示，操作每个回路（包括控制模式、设定值、设定串级、输出信号调整等），报警确认，执行打印机的各种功能。 Operating keyboard directty operated by operator is normal. Finding all indications and operating every loop (including control module, set data, setting series—level, output signal ). Alarming and Executing all functions. 2) 确认由键锁或口令启动的操作员键盘功能操作正常，能改变测量范围，报警值及输出信号限制等。 Making sure keyboard function locked by key or password is normal. It can change measuring range, alarming data, and output signal restrict. 打印机、拷贝机用报表测试 Testing chart for printer and copier. 1) 检查打印机能将操作站规定的信息进行打印。 Checking printer can print information specified by operation station. 2) 确认报警打印自动发生，排列顺序与报警汇总画面一致。 Affirming alarm—printing automatically. Sequence keep pliance with alarm collection screen. 3) 检查“确认”或“恢复”时间的打印与实际发生时间相同。 Keep printing time of verifying and re。
