DC1010 - DC1020 - DC1030 - DC1040General Purpose DIGITAL CONTROLLERSPRODUCT SPECIFICATION SHEETDC1010 (1/16 DIN) DC1020 (1/8 DIN)OVERVIEWThe DC1000 family ofmicroprocessor based controllers combine a high degree offunctionality and reliability at a very low price. Available in 4 different formats : 1/16 DIN, 1/8 DIN, 3/16 DIN, 1/4 DIN. These controllers are ideal for regulating temperature in a variety of applications, including : x Dryers.x Semiconductor packaging /testing.x Plastic processing.x Packaging machinery.x Painting and coating.x Climatic chambers.The DC1000 family provides basic control requirements, plus advanced features such as motor position control, phase angle power control and Setpoint programming.FEATURESDC1030 (3/16 DIN)DC1040 (1/4 DIN)Easy to configureTwo different configuration levels provide easy access to parameters. A 4-digit security code prevents unauthorized changes. Parameters can also be hidden to the user to prevent mis-configuration of the unit. Various Control algorithms The DC1000 series of controllers provide several different algorithms: x PID or ON/OFF control.x Heat/Cool algorithms with 2different PID sets.x Motor position control withoutslidewire feedback.x Single phase control, with orwithout zero crossover control. x Three phase control, with orwithout zero crossover control.Dual display and BargraphTwo large 4 digits displays and one 10 LED bargraph display PV, SP andconfiguration parameters. Up to 8 LEDs display the status of the different Outputs (Control, Alarm, …) and also provides indication of the Auto/Manual and Programmer states.Setpoint ProgrammingTwo programs are available, with amaximum of 8 segments. The 2 programs can be linked together to form a single 16 segment program.Extended Alarm capability Three different alarm outputs areavailable per instrument, 17 alarm modes are configurable.CommunicationsRS232 or RS485 ASCII protocol is optionally available. Up to 30 DC1000 Controllers can be connected to a single host computer. The host computer can change the SP, monitor the PV, the output or change the configuration of the unit.Remote Setpoint capability. Manual / Automatic modes.

CE Mark.x PID or ON/OFF control.x Heat/Cool algorithms with 2 different PID sets.x Phase angle controlSingle PhaseThree Phase3I LOADIn phase angle control, power is regulated by changing the point at which the SCR is turned on within each 1/2 period. Single Phase : Output is changed every half-cycle in response to output signals from the Temperature Controller. Three Phase : The outputs are changed every 120° in response to signals from the Temperature Controller. Using this form of control, high-precision temperature control is possible.x Zero-crossover controlSingle Phase1I LOADThree Phase3I LOADThe term Zero-Crossover means that the SCR's are turned on only when the instantaneous value of the sinusoidal wave is zero. Power is then applied for a several continuous half-cycles and then removed for several half-cycles to achieve the desired load power.x Motor position control without slidewire Feedback.MOTOR VALVEMotor position is achieved by using time proportional controlwithout the need for slidewire feedback from the motor shaft. Slidewires wear over a period of time, which can result in poor or intermittent control. This type of control reduces maintenance requirements and removes the need for the controller to be calibrated to the motor feed back potentiometer.DC101050 mm - 1.97 in74.5 mm - 2.97 in13.5 mm 0.53 in6 mm 0.24 in 44 m m - 1.73 i n50 m m - 1.97 i n68 mm - 2.68 in60 m m - 2.36 i n45.5 mm - 1.79 in 45.5 m m - 1.79 i nDC102074.5 mm - 2.97 in13.5 mm 0.53 in6 mm 0.24 in86 mm 3.39 in96 m m - 3.78 i n48 mm - 1.89 in60 mm - 2.36 in91mm 3.58 in45.5mm 1.79 in116 mm 4.57 inDC103074.5 mm - 2.97 in13.5 mm 0.53 in6 mm 0.24 in66 m m - 2.60 i n72 mm - 2.83 in72 m m - 2.83 i n91 mm - 3.58 in69.55 mm 2.74 in91 m m - 3.58 i n69.55 mm 2.74 inContact Details:Industrial Supply Syndicate54, Ezra Street, Kolkata - 700 001, INDIAPhone: 22350923, 22356676 Fax: 91-33-30222923。

DCS系统配置说明
![DCS系统配置说明](https://img.taocdn.com/s3/m/1f88aa1b866fb84ae55c8d0c.png)
TELEPERM® XP DCS系统配置说明本方案是为定洲电厂一期工程2×600MW机组所配置的分散控制系统,其配置基准参照技术规范书中的I/O清单。
本配置方案见第三卷附件15的DCS配置图,其技术细节见以后各章节。
我方保证本方案所供设备是适用的,先进的,能适用于定洲电厂一期工程2×600MW机组,并能全面满足用户的要求。
一、概述西门子TELEPERM® XP分散控制系统是以电厂安全、经济、优化运行为目标的电厂分散控制系统,它紧密结合电厂的实际生产过程,以功能及被控设备为对象,经分层及分布的软硬件设计,统一的数据管理和数据格式以及人机接口来实现最优化的控制及运行策略。
TELEPERM® XP系统在硬件及软件分配上并不完全以DAS、MCS、SCS及FSSS来设立子系统,而是以被控对象以及功能区域来设立子系统,如给水系统、燃烧系统、风烟系统等。
这样的分配方案面向现场,使得一个设备的控制,包括输入/输出、报警、联锁相对集中在一块或几块模件,一个子系统的控制集中在一个CPU中,提高了单一对象处理的独立性,大大减少了DCS系统内信号的通讯量。
大量的事件处理在I/O总线内,甚至在智能I/O模件内实现,而不需要经过通讯总线,既提高了安全性,又降低了总线通讯的负荷。
TELEPERM® XP系统的控制等级可分为机组级,功能级,单项级,见下图:机组级功能级单项级过程设备TELEPERM® XP系统的控制等级TELEPERM ® XP 系统可分为 AS620(自动控制系统),OM650(操作监视系统), ES680(工程设计系统)及 SINEC H1 FO (总线系统),见下图:TELEPERM ® XP 系统组成从功能上说,AS620主要实现电厂的自动化控制(安全运行),OM650主要实现过程控制,过程信息及过程管理(经济及优化运行),SINEC H1 FO 主要完成数据通讯, ES680主要完成系统的组态。

Attach Wireless Antenna(DCS-1000W only)From the rear panel of the Internet Camera, screw the 2 external antennas that came with DCS-1000W into the antenna connector.2. Configure Network CommunicationFrom the rear panel of the Internet Camera select the desired network communication for the Internet Camera from the Slide Switch. Position the Slide Switch to the setting required for either LAN or LAN/WLAN (DCS-1000W only) position.Please refer to the Physical Description section for detailed information.3. Connect an Ethernet cableConnect an Ethernet cable to the network cable connector located on the Internet Camera’s rearpanel and attach it to the network.4. Attach the external power supplyAttach the external power supply to the DC power input connector located on the Internet Camera’s rear panel and labeled DC 5V and connect it to your local power supply.Note:The LED indicator labeled Power will illuminate to indicate a proper connection to the power supply.Hardware InstallationThe Internet Camera comes with a camerastand with a swivel ball screw head that can beattached to the Internet Camera bottom bracketcavity. Attach the camera stand to the InternetCamera and station it for your application. Thereare three holes located in the base of the camerastand allowing the Internet Camera to bemounted on the ceiling or any wall securely .Connecting the Internet Camera to the Camera Stand SecurityTo ensure the highest security and prevent unauthorized usage of the Internet Camera,the Administrator has the exclusive privilege to access the System Administration setting to allow users the security level of entry and authorize privileges for all users. The Internet Camera supports multi-level password protection/access to the Internet Camera that can be restricted to defined users who have a User Name and User Password which is assigned by the Administrator.The administrator can release a public user name and password so that when remote users access the Internet Camera they will have the right to view the image transmitted by the Internet Camera.Note:When the Internet Camera is used for the first time it is highly recommended that the Administrator set the Admin ID and Admin Password to constrain user access to the Internet Camera since the Default settings are Null String (no password). Once the ID and Password are defined only the Administrator has the access to the management of the Internet Camera. This procedure should be done as soon as possible since the security features of the Internet Camera will not be enabled until the Admin ID and Admin Passwordis defined.Using the Internet Camera as aSecurity SystemD-Link's IP Camera System is one of the most costeffect security solutions today. Both the DCS-1000Wired model and DCS-1000W Wired/Wireless modelhave input/output controls for interfacing with securitysystems.On the back of the Camera you will find an 8-positionconnector. This connector has 2 input triggers forsecurity sensors and 2 output triggers for securityalarms.Security sensors for input are available as Passive(low-current/low voltage) sensors or Active (powered)sensors.Because of power limitations of the DCS cameras and its compatibility with Power over Ethernet standards the sensor power requirement must be obeyed for proper operation.We have listed Passive and Active components that will interface with the DCS family of Cameras. Passive components must not exceed 5V 100mA. Active components must be self-powered by an external power source.As an example for a typical installation is shown below: a D-Link DCS-1000 was purchased from , the security equipment was purchased from , and some cable accessories from a local hardware store.MaterialsYou will need some simple tools like wire cutters/strippers and an appropriate screwdriver for mounting the distribution block setup.Everything less the camera costs about $97 US Dollars including shipping.•DCS-1000• 2 Ethernet Cables & Ethernet Switch/Internet Router•An Ethernet based PC to configure system•Internet Name Server and E-Mail Server to send capture information •10FT. 24Gauge• 1 light current power distribution block for 12V power•30W Weatherproof Siren•High Sensitivity DPDT relay (allows 5V camera to turn on 12V siren)•Mini-Magnetic Contact Switch (commonly used for doors or windows)•PIR Motion DetectorBasic Hardware Set-up DiagramThe diagram below shows the hardware configuration for 1 Active Sensor (PIR Motion Sensor), 1 Passive Sensor (Magnetic Switch), and 1 output (For Relay) for a siren.Passive Component Notes!!!Only simple magnetic or contact switches can be used for Passive components. This limitation is because the camera only supplying 5V and less then 100mA current to those circuits. Distance for passive components is limited by a viewable camera range of about 25 Ft using 26GA wire.Active Component Notes!!!A separate power supply is needed for these devices. In order to choose the proper PS. The total current draw by all the components cannot exceed the Max current supplied by the power supply.ExampleOur PIR Motion Detector = 17 mA = .017AOur Relay = 60 mA = .06ASiren = 200mA = .20ATotal : .277APurchase a 12V DC 1.2A Max power adapter to cover all Active Sensors and Siren, with room to grow.Camera ConfigurationFollow the instructions for setting up the camera either wired/wireless. If this is a home and the camera is behind an Internet router additional set-up notes for you router can be found on .Once logged into the camera on the main menu click/select trigger and the following screen will appear.These fields control Input Trigger 1 and Trigger 2. Each Input trigger can trigger either or both Output triggers.SMTP Server Address: Name or IP address of a Mail Server that the camera can use to send images by e-mailSender E-Mail: Name of the Camera who sent the mailReceiver E-Mail: Name of the person to receive the pictures when the sensors are activatedSending Interval: The time between additional sequences of pictures are taken when the sensors are activatedSending Times: The number of times the camera takes additional sequences of pictures based on Sending Interval.Trigger I/O: Enable Output trigger for the specified input triggerOutput # Time: How long the output trigger is activated if the sensor is activated. (ie. How long should the siren ring?)INPUT TRIGGER RESPONSE NOTES!!!The camera will take a sequence of pictures and the output trigger is activated when there is a change, open or close of the sensor. Example: The magnetic switch is opened, a sequence is sent and siren goes off. The switch is then closed, an additional sequence is sent and the alarm goes off. The camera is designed this way so if there is an intrusion, the intrusion is detected if the intruder simply opens t and closes the door.Additional Component Listing for use with the Internet CameraAll components listed below can be found at Passive ComponentsGlass Break Sensor PN: 5150w - Sentrol Inc.Any contact switch or pressure switch not exceeding 100mW current draw.Examples at /seccontacts.htmlActive ComponentsCoral Plus Temperature Compensated PIR Detector - Visonic Ltd.Duet Dual Microwave/ IR Motion Detector - Visonic Ltd.Bravo 6 Dual PIR Detector - DSC Security ProductsAny active security sensor that uses external power and a separate normally closed N/C circuit for detection: examples at /secpirmotion.html Power and Relay ComponentsELK Products Inc.

To configure your Internet Camera type “http://192.168.0.20” in the address box of your favorite Web Browser. The number is the default IP address of your Internet Camera. Press Enter.Note:The PC’s IP address must correspond with the Internet Camera’s IP address in the same segment (i.e. PC=192.168.0.5, Camera=192.168.0.20) for the two devices to communicate. For instructions on how to do this, please access instructions for installing any of the D-Link Broadband Gateway products from / products. The DI-713 or DI-714 are good products to use as an example as their Quick Install Guides are the most up-to-date.Main Menu ImageAfter the default IP address is entered from the Browser, the Internet Camera Home screen will appear with a still image. There will be three options to choose from to set-up and view your Internet Camera and they are as follows:View Image – ActiveX ModeView Image – Java ModeSystem AdministrationSystem AdministrationClick on “System Administration” from the Home screen to access the settings required for the Internet Camera.There will be several options in the System menu bar to choose from to set your Internet Camera and they are as follows:SystemImageUsersDate/TimeTriggerInformationT oolsSystem AdministrationSystem Administration – SystemThe System menu contains commands for settings that are required for inputting key details to set-up the Internet Camera for operation.Click on System in the System Administration menu bar and the System screen will appear as illustrated below:Camera Name:This field is used for entering a descriptive name of the device.The default setting for the Camera Name is CS-xxxxxx, where xxxxxx is the last six digits of the MAC Address. The maximum length is 32 characters (Printable ASCII). Location:This field is used for entering a descriptive name of the location used by the Internet Camera.Admin:This field is used for entering the Administrator ID along with the password to access the System Administration settings. Be sure to enter the password twice to confirm , once in the Admin Password field and again in the Confirm Password field.The default setting for Admin is blank (Null String) you need to key in the Admin ID with a maximum length of 12 (Printable ASCII) characters and enter the Admin Password with a maximum length of 8 (Printable ASCII) characters.It is highly recommended that you set the Admin ID and Admin Password as soon as possible to ensure the highest possible security.IP Assignment:There are two options to select from the IP Assignment, either Manually Assign or Assign Automatically Using.Manually AssignYou can click “Manually Assign” and directly enter the IP address.The default settings are as follows:Default IP – 192.168.0.20Subnet Mask – 255.255.255.0Default Gateway – 0.0.0.0Assign Automatically UsingImportantIt is recommended that you do not use an Automatically Assigned IP address as it may be difficult to determine the IP address of the unit after the IP address has been asssigned. It is recommended that an IP address be assigned manually.If your network is using RARP, BOOTP or DHCP server you can click Assign Automatically Using and click on RARP, BOOTP or DHCP. Under this setting the Internet Camera will automatically assign an IP address from RARP, BOOTP or DHCP server. Each time the Internet Camera starts up, be sure the RARP, BOOTP or DHCP server is setup to assign a static IP to your Internet Camera.If your application requires direct connection from an ADSL modem through the Internet Camera’s RJ-45 LAN port and you also have an ISP PPPoE account, the cick on PPPoE and enter the Service Name, User ID and Password into the respective fields. The Internet Camera will get an IP address from the ISP each time it starts up.DNS IP Address:DNS (Domain Name System) server is an Internet service that translates domain names (ie. ) into IP addresses (ie. 192.168.0.20). The DNS IP address can be received from your ISP. Enter at least one DNS IP Address.Wireless Interface:Connection Mode:Use the Connection Mode to determine the type of wireless communication for the Internet Camera. There are three choices of Infrastructure mode, 802.11 Adhoc mode and Adhoc mode. The default setting for the Connection Mode is Infrastructure. Note: (for Wireless Internet Camera only)Keep in mind that after setting the Wireless Interface make sure that the Slide Switch on the rear panel is positioned to either LAN/WLAN or WLAN setting for the wireless communication to take effect.Network Name: (for Wireless Internet Camera only)This field is used to setup which wireless network (ESS-ID Extended Service Set ID) DCS-1000W is to be connected for communication. The ESS-ID is a unique identifier shared among all points in a wireless network environment.The default Network Name is a blank space (NULL String); this default setting will let the Internet Camera connect to any access point under the infrastructure network mode.To connect the Internet Camera to a specific access point on the network make sure that you set the ESS-ID of the Internet Camera to correspond with the access point’s ESS-ID. Type any string up to 32 characters long (spaces, symbols, and punctuation are not allowed) in the Network Name box.To connect the Internet Camera to an Ad-hoc wireless workgroup make sure that you set the same wireless channel and ESS-ID to match with the PC/Notebook wireless channel and ESS-ID for direct wireless communication under the Ad-hoc wireless workgroup (ad-hoc and 802.11 ad-hoc modes).Note:The Internet Camera supports two ad-hoc modes (802.11 ad-hoc mode and proprietary ad-hoc mode). Which option of the ad-hoc mode required depends on the operation of your Internet Camera. It depends on which ad-hoc mode is supported by your wireless card driver on the PC/Notebook. Some drivers supports both modes, however, some drivers support only one of the modes. The names of each ad-hoc mode may not be consistent between each wireless card vendor therefore you may need to try each of the ad-hoc modes (802.11 mode and proprietary mode) and select the mode that can communicate with each other.Wireless Channel: (for Wireless Internet Camera only)The pull down menu provides the wireless channel for communication. A “channel” is a range of frequencies to be used in communication between the Internet Camera and Access Point in infrastructure mode or the Internet Camera and PC/Notebook in Ad-hoc mode. Select the appropriate channel from the list provided depending on the regulatory region in which the unit is sold. The default setting is channel 11.Encryption WEP Key: (for Wireless Internet Camera only)Wireless network communications are easily intercepted. WEP (Wired Equivalent Privacy) is an encryption method specified by the IEEE 802.11b standard to make any intercepted communications extremely difficult to interpret by unauthorized parties. To enable WEP Encryption, first decide which WEP key format will be applied. Click on ASCII or HEX check box to select input format as ASCII format or HEX format, and then input the WEP key. To Confirm the WEP key you must enter the data once again in the Confirm WEP Key field.ASCII input format: (for Wireless Internet Camera only)ASCII format causes each character you type to be interpreted as an eight-bit value. All unaccented upper- and lower-case Western European characters that can be input through your keyboard’s typing zone are valid. To setup 64-bit WEP key, input 5 ASCII characters, for example, ‘12345’. To setup 128-bit WEP key, input 13 ASCII characters, for example, ‘1234567890123’. These character counts result in bit counts of 40 and 104, respectively; the Internet Camera will automatically pad your input to a bit count of 64 or 128.HEX input format:(for Wireless Internet Camera only)Hex format causes each pair of characters you type to be interpreted as an eight-bit value in hexadecimal (base 16) notation. Only the digits 0 through 9 and the letters A through F (in upper or lower case) are valid. To setup 64-bit WEP key, input 10 HEX format, for example, ‘3132333435’, this is the same with ASCII input ‘12345’. To setup 128-bit WEP key, input 26 HEX format, for example, ‘31323334353637383930313233’, this is the same with ASCII input ‘1234567890123’. These character counts result in bit counts of 40 and 104, respectively; the Internet Camera will automatically pad your input to a bit count of 64 or 128.On the Confirm WEP Key field, input the same characters as the Encryption Code field.Make sure the Encryption Code is the same with the access point’s encryption code that the Internet Camera is to be connected under Infrastructure mode. Your PC/ Notebook’s encryption code also needs to be setup the same with the Internet Camera’s encryption code under either Infrastructure mode or Ad-hoc mode.The default setting for the Encryption Key is Disable. Therefore, to secure the wireless transmission be sure to Enable the Encryption Key by entering the relevant data. Note:Carefully input the Encryption Code, any error setting the code will cause the communication link to fail.LED Control:The LED control allows you to setup the LED illumination as desired. This feature provides the flexibility when surveillance activity is ON.There are three options as follows:NormalPower - Steady On of the LED indicator.LAN/WLAN - Steady On of the LED indicator. When LAN/WLANactivity is present the LED indicator will flash steadily.OFFPower - LED indicator is offLAN/WLAN – LED indicator is offDummyPower - Steady On of the LED indicator.LAN/WLAN - Steady On of the LED indicator with random flashing.Note: The WLAN LED is only available on the Wireless Internet CameraThe default setting for the LED control is Normal. When you have configured the LED control the correct illumination will set in after 1 minute.Note:This function is built-in to the LED indicators to add extra capabilities. The three options allow the Administrator to configure and camouflage the illumination for the LED indicator to falsify the monitoring status. In Normal Mode the LED indicator functions normally. Under Off Mode the LED indicators are both off, however, it is still monitoring the activity. In Dummy Mode the LED indicators operate in monitoring condition but monitoring activity is off or on.Loading ActiveX From:This field is used to specify the location of Xplug Control (ActiveX) plug-in program. Enter the information as required in .ocx format, for example:http://www.<your company>.com/xplug.ocx where <your company> must be replaced with your company’s DNS server.。

曙光DCstor 私有云存储系统教战手册曙光信息产业(北京有限公司产品中心2011年5月目录1.教战手册作用2.常见问题及解释2.1.什么是云存储,什么是私有云存储2.2.搭建云存储系统需要考虑哪些因素2.3.曙光DCstor 主要有哪些特性2.4.DCstor私有云存储系统的产品主要定位在哪个市场2.5.曙光DCstor产品规格有什么优势1. 教战手册作用曙光DCstor私有云存储教战手册是销售人员在与客户沟通时常见问题的回答要点,是让客户清楚曙光DCstor产品能做的事情以及曙光的优势,为最终达成销售而提供必要的技术解释。
2. 常见问题及解释2.1. 什么是云存储,什么是私有云存储云存储是指通过集群应用、网格技术或分布式文件系统等功能,将网络中大量各种不同类型的存储设备通过应用软件集合起来协同工作,共同对外提供数据存储和业务访问功能的一个系统。
云存储支持两种实施模式:公有云(Public Cloud和私有云(Private Cloud。
公有云是由专门机构提供存储空间,作为一种服务提供给客户,客户可以通过支付一定的费用获得这种服务,从而可以将自己数据通过网络传输并存储到这些存储空间中。
用户不需要了解云存储中使用的技术,也无需为数据的维护和安全性付出任何人力物力成本,这些全部由提供云存储服务的公司来承担;私有云是在企业或者相关机构在自己的计算中心或数据中心内部构建的弹性存储池并由企业或相关机构完全控制。
私有云存储往往需要建立在数据中心的防火墙后面,使用数据中心所拥有或授权的硬件和软件。
数据中心的所有数据保存在内部并且被完全控制着。
这些员工样就可以使用集中管理的存储空间来实现不同部门的存储需求,无论他们的物理位置在哪。
云存储的优势明显:多应用、多租户、多层、多点、安全、可预测、高效、自动。
“云”同时也意味着虚拟化,采用虚拟化技术,配合例如自动存储分层、自动精简配置等必要的工具,可以应对自动化的共同复杂任务,从而使系统能够在正确的存储资源,以合适的时机,自动迁移数据。

2、固定前端1颗螺丝设备连接前后面板示意图图3 面板示意图设备连接说明DCS作为分布式集群存储系统,可通过多个节点的集群扩展实现叠加的容量性能。
由于DCS节点间存在数据传输与心跳通信,因些需配置专门的高速内部交换网络。
每个DCS节点都有专用的万兆私网接口,集群系统工作之前需要通过内部万兆交换机将所有节点连接至一个网络,实现内部通讯管理。
DCS标配万兆以太网主机接口,因此还需要将每节点的万兆主机接口连接至用户业务交换机,以实现客户端正常访问。
可选配置千兆、万兆、Infiniband主机业务接口。
