FOXBORO控制器  由于工业生产过程是一个分散系统，因此过程控制的方式是分散进行，操作和化管理应以集中为好。随着工业生产规模不断扩大，控制管理的要求不断提高，过程参数日益增多，控制回路越加复杂，在控制系统，一经出现就受到工业控制界的青睐。DCS是集计算机技术、控制技术、网络通信技术和图形显示技术于一体的系统。与常规的集中式控制系统相比有如下特点：
1、实现了分散控制。它使得系统控制分散、可靠性高、减小、维护方便。
2、实现集中监视、操作和管理。使得管理与现场分离，管理更能综合化和系统化，

在线维护与修改所有I/A Series组件均可无扰动在线更换，无需切断电源，无需采用防静电措施。I/ASeries可以在线修改控制组态和应用软件，在线修改不会对系统产生任何扰动。I/A Series还可以在线增加FBM卡件。数字控制机床还有加工中心在现代社会一形成了全自动化的实时控制系统，运用可靠性较高的元器件去加速设备的运转工作，可以使控制系统在出现机械故障的时候快速的运用诊断方案去找到原因，并及时处理，减少机电一体化设备的损耗。但这个办法都是要中途停止正在运作的设备才能找出故障原因。

In order to ensure safety production and realize emergency treatment of emergency accidents, the external automatic tracking regulator is installed on the six regulator circuits. In case of control system failure, the tracking regulator is automatically switched to control the regulating valve independently of DCS; 21 main valves are equipped with emergency treatment button, which is independent of DCS to realize forced switch on the valve. 2.3. hardware configuration:

Omron C200 PLC is selected in the control station, and 9 digital modules (od211/ id212), 4 analog modules (ad003) and 3 regulating modules (pid03) are configured; The operation station adopts Dell opt gx150 computer; The engineer station adopts compa PC. The composition is as follows:

2.4. software configuration of control station:

The configuration of control station is based on the system software SSS of OMRON as the technical platform and ladder diagram as programming tool. The configuration contents are as follows:

2.4.1.allocation of PLC internal address:

I/o address distribution: the i/o address of PLC is the only one-to-one register address for data communication between PLC and field detection equipment and actuator. The allocation of i/o address is the basis for further configuration of PLC; For omron-c200, i/o address is related to the connected i/o module; The i/o address of the field equipment connected to the digital module depends on the installation position and the point number on the module. The i/o address of the field equipment connected to the analog module and PID module depends on the unit number of the i/o module (different modules shall be set with different unit numbers through the hard opening and closing of the module) and the point number on the module; For example, in the configuration of this system, the analog signal of 4-20mA output by the radar level transmitter LT-101 on site is connected to the second point of analog input module ad003 with unit number 3, the address of its configuration in PLC is ir:132; When the closed signal of valve hv120 is connected to the tenth point of the digital input module id212 installed in the second slot of the expansion rack, its configuration address in PLC is ir:01210; In this system, 142 i/o addresses are defined.

I/A Series system features

The SYSTEM consists of PROCESS CONTROL STATIONS, PROCESS OPERATION STATIONS, and ENGINEER WORKSTATIONS/APPLICATION COMPUTING PROCESSING stations, INFORMATION management stations, and COMMUNICATION SYSTEMS.

(1) Process control station

The process Control station of I/A Series is called Control Processer (CP).

CP itself is a multiprocessor system consisting of:

Network communication processor

I/O bus communication processor

Control processing machine

The CONTROL PROCESSOR DETECTS and/OR ISOLATES FAULTS USING three types OF DIAGNOSTIC TEST procedures: POWER-ON SELF-TEST, RUNTIME and MONITOR CLOCK CHECK, AND OFFLINE DIAGNOSIS. Considering the requirement of process reliability, this system is equipped with CP40B.

The control processor is connected to various fieldbus components (FBMS) via fieldbus, that is, I/O cards.

The fieldbus connects CP and FBM. Provides high-speed fault-tolerant communication, communication rate is 268.75 KBPS, communication protocol IEEE1118, using shielded twisted pair, the maximum distance is 1800 meters.

Analog fieldbus components (FBMS) are single-channel isolated, one-to-one A/D converters. Each channel uses electrical isolation and photoelectric isolation technology, I/O circuit uses overcurrent protection technology, without the use of fuses, improve the reliability of the system. Because of the reliable and long-distance fieldbus, users can place I/O cabinets to the field. Two shielded twisted pair cables can replace hundreds of thousands of expensive field wires of the same distance, such as temperature compensation wires. I/A Series also has the ability to add or subtract FBM cards online without any impact on the process.

(2) Engineer station and operation station

Engineer Station and Operating station The operating station uses SUN's 64-bit workstation. It supports industry standard communication protocols, such as TCP/IP and DECNET, and can be very convenient to connect with the factory information network.

I/A uses SPARC technology. X-window System as an operating platform, on the network, any computer running WINDOWS, its application program can be accessed from this computer or to another computer to run remotely, so as to reasonably use various resources on the network. X-windows systems, designed for networking from the start, have consistently supported industry-standard Ethernet. Several protocols such as TCP/IP, OSI, and DECNET are also supported for connectivity to large and small machines and networks. On the 50 series, you can also connect directly to the INTERNET.
