根据设计院提供的相应图纸,对点表进行整理,整理,一般在EXCEL表中包括位号、名称、信号类型、量程、单位、报警值(如有)I/O点数。
Sort out the point table according to the corresponding drawings provided by the design institute. Generally, the excel table includes the tag number, name, signal type, measuring range, unit, alarm value (if any) and i/o points.
浙大中控dcs卡件XP313厂家根据DCS具体分配制造商提供的卡类型DCS的I/O根据测点的类型,将通道分配到特定的通道中,需要小心,不要出错。
Zhejiang University central control DCS card xp313 manufacturer assigns the card type provided by the manufacturer according to the DCS. DCS i/o assigns the channel to a specific channel according to the type of measuring point. Be careful not to make mistakes.
不同品牌的DCS系统硬件配置不同,但配置思路和方法相同:DCS系统硬件是根据现场的准确需求和DCS系统I/O确定点数。DCS以下内容需要完成系统硬件配置:与控制相关的冗余配置改进DCS可靠性的重要手段,DCS系统冗余通常包括电源冗余、控制器冗余、通信冗余、操作站冗余和DCS系统I/O板卡冗余;
DCS system hardware configurations of different brands are different, but the configuration ideas and methods are the same: DCS system hardware determines the number of points according to the accurate needs of the site and DCS system i/o. The following contents of DCS need to complete system hardware configuration: redundant configuration related to control is an important means to improve DCS reliability. DCS system redundancy usually includes power redundancy, controller redundancy, communication redundancy, operation station redundancy and DCS system i/o board redundancy;
根据系统的要求和控制规模配置插件(CPU插件)、电源插件、I/O硬件设备,如插件、通信插件等;DCS安装系统笼DCS不同制造商的卡件模块DCS系统机笼配置要求各不相同,但基本都是按照卡件数量配置相应的机笼,卡件数量固化下来后就可统计出机笼数量;
Configure plug-ins (CPU plug-ins), power plug-ins, i/o hardware devices, such as plug-ins, communication plug-ins, etc. according to system requirements and control scale; DCS installation system cage the configuration requirements of DCS system cages for card modules from different manufacturers are different, but the corresponding cages are basically configured according to the number of cards. After the number of cards is solidified, the number of cages can be counted;
DCS机柜用于放置各种插件、机笼和中间继电器,DCS机柜的常见尺寸为2000*800*800mm,机柜的数量取决于安装的插件、笼子和中间继电器的尺寸和数量。
DCS cabinet is used to place various plug-ins, cages and intermediate relays. The common size of DCS cabinet is 2000*800*800mm. The number of cabinets depends on the size and number of installed plug-ins, cages and intermediate relays.
软件安装:一般由DCS安装厂家人员,检查配置,启动系统,只配合好。
Software installation: generally, the personnel of DCS installation manufacturer shall check the configuration, start the system, and only cooperate well.

根据DCS制造商提供系统,启动组态软件;对应点表和相应的通道,不要出错;根据控制方案组态PID调节回路;组态纯显示回路;组态开关量控制电路和小型联锁电路,如泵启停;组态顺控部分有序控制;
Start the configuration software according to the system provided by the DCS manufacturer; Do not make mistakes in the corresponding point table and the corresponding channel; Configure the PID regulating circuit according to the control scheme; Configure pure display circuit; Configure switch control circuit and small interlocking circuit, such as pump start and stop; Orderly control of configuration sequence control part;
浙大中控dcs卡件XP313厂家认为DCS显示控制图这部分很重要。用户看到的是图片,其他人看不到。DCS流程图,多看几遍,基本了解物料流向和流程,然后与甲方用户沟通,放在显示面上。先在系统图片组态软件中画出图片,然后联系甲方工艺人员修改图片,直到满意为止。尽量选择子图模式,使效率提高。到目前为止,一套完整的DCS随着调试过程的不断完善,系统基本建立,较终形成一套完整的系统DCS控制系统。
Zhejiang University central control DCS card xp313 manufacturer thinks that DCs display control chart is very important. What users see is a picture, which others cannot see. Read the DCS flow chart several times to basically understand the material flow direction and process, and then communicate with Party A's users and put it on the display surface. First draw the picture in the system picture configuration software, and then contact the process personnel of Party A to modify the picture until they are satisfied. Try to select sub graph mode to improve efficiency. So far, with the continuous improvement of the commissioning process, a complete set of DCs has been basically established, and finally a complete set of system DCS control system has been formed.
