ENK32 GE EAE以太网模块 现场总线的集散控制系统

产品描述

ENK32是基于工业以太网和现场总线的集散控制系统(DCS),在基本组成基础上，扩充了专用功能站、生产管理和信息处理的信息网络、实现现场仪表和执行机构数字化的现场总线网络。控制站直接进行现场I/O数据采样、信息交互、控制运算及逻辑控制，完成整个工业过程中的实时控制，并实现各种I/O接口。现场总线系统采用CAN总线，改变系统现场信号线的接线方式，使DCS在现场检测和控制执行方面被数字化。

控制站是系统中直接与现场进行I/O数据采样、信息交互、控制运算、逻辑控制的核心单元，完成实时控制功能，并实现各种I/O接口。

控制站通过工业以太网与工程师站、操作员站等交换信息，采集控制站信号并通过工业以太网传送到工程师站、操作员站，工程师站、操作员站将.系统组态信息通过工业以太网传送到控制站。

控制板是控制站的核心，负责协调所有软硬件关系和各项控制任务。并为主控板完成各种操作。另选一块作为备用控制板，实时监测主控板运行状态和工作参数，当出现异常时，立即转为主控板，接替原主控板工作。互为备用的2块控制板采用现场总线进行信息交换。

为保证系统可靠性和稳定性，每个控制板.上设置2路独立的CAN接口，构成环回结构，如线路出现–处断线仍可保证系统正常通讯。

Product description

ENK32 is a distributed control system (DCS) based on industrial Ethernet and fieldbus. On the basis of the basic composition, it expands the special function station, the information network of production management and information processing, and the fieldbus network to realize the digitalization of field instruments and actuators. The control station directly carries out on-site I/O data sampling, information interaction, control operation and logic control, completes the real-time control of the entire industrial process, and realizes various I/O interfaces. The fieldbus system uses CAN bus to change the wiring mode of the system field signal line, so that DCS can be digitized in the field detection and control execution.

The control station is the core unit of I/O data sampling, information interaction, control operation and logic control directly with the field in the system, which completes the real-time control function and realizes various I/O interfaces.

The control station exchanges information with the engineer station and the operator station through the industrial Ethernet, collects the signal of the control station and transmits it to the engineer station and the operator station through the industrial Ethernet. The system configuration information is transmitted to the control station via industrial Ethernet.

The control board is the core of the control station and is responsible for coordinating all the relationship between hardware and software and various control tasks. And perform various operations for the main control board. Select another control board as a standby control board to monitor the running status and working parameters of the main control board in real time. When an exception occurs, it is immediately converted to the main control board and takes over the work of the original main control board. The two alternate control boards use fieldbuses for information exchange.

To ensure system reliability and stability, each control board. Two independent CAN interfaces are configured to form a loopback structure. If a line is broken, the system can still communicate normally.
