05701-A-0302功能模块备件HONEYWELL一、保护网络工业公司应确保自身网络设计良好，有着防护周全的边界。企业应按 ISA IEC 62443 标准划分自身网络，
保护所有无线应用部署能快速排除故障的安全远程访问解决方案。公司网络，包括其工业网络基础设施设备，都应列入监视对象范围。
二、保护终端
运营技术(OT)团队可能会觉得公司的终端受到边界防火墙、安防软件、*协议和物理隔离的防护，可以抵御数字攻击。但事实不是这样的，雇员、承包商和供应链员工将他们的笔记本电脑或U盘带入企业网络时，这些安全防护措施就被绕过了。
必须确保所有终端都是安全的，要防止员工将自己的设备接入公司网络。事实上，黑客可以侵入OT环境中基于PC的终端。公司企业还应保护其IT终端不受OT环境中横向移动的数字攻击侵袭。
购买资产发现产品，或者实现网上终端清点过程，是保护终端安全的不错开端。可以定义控制措施和自动化以确保防护到位。然后公司企业必须保证每台终端上的配置是安全的，并监视这些终端以防遭到未授权修改。
体上，IT和OT环境通用的解决方案是公司企业明智的选择。应定义一个足够灵活的安全平台，既能够深度覆盖IT，又适用于敏感的OT环境。
三、保护控制器
每个工业环境都有其物理系统——致动器、校准器、阀门、温度感应器、压力传感器一类机械装置。这些与现实世界交互的物理系统被称为控制器，也就是桥接物理系统控制和网络指令接收行为的特殊计算机。很多案例中恶意黑客都曾获取过这些设备的控制权，引发设备故障，造成物理破坏，或对公司的损害。不过，如果仅仅是能访问而不能控制，恶意黑客也无法直接造成破坏。
通过加强检测能力和对ICS修改及威胁的可见性，实现脆弱控制器的安全防护措施，监视可疑访问及控制修改，以及及时检测/控制威胁，公司企业可有效防止工业控制器遭到数字攻击。
网络犯罪已成当今世界发展*快的产业。其范围涵盖仅仅出于好玩就发起攻击的脚本小子，以及像跨国公司一样运营的犯罪组织。随着ICS成为网络罪犯的主要目标，公司企业需采取措施做好ICS对数字威胁的防护。而要做好防护，就需要重点放在网络安全、终端安全和工业控制器安全的多层安全措施。由于控制中心选用AB公司的PLC构筑自控系统，并采用DH+网络实施远程联网。为保持一致性，空压站自控设备选用AB公司的小型PLC ——SLC-500系列可编程控制器，其带有DH+网络接口，支持DH+和DH-485网络协议。原设计为单一DH+网络结构，后仔细分析了生产实际情况和各设备的特点，以及可能存在的问题，综合各方面因素后确立了分级控制网络的实施方案。
其基本理由是：
1） 技术性考虑，单一结构网络在节点数量较大时安全性不够理想。因为各设备控制器均挂在同一网络上，任何一台出现通信故障都可能影响整个网络，严重时会引起网络瘫痪，无法实现远程监控。虽然本案例的设备数并不算很多，但考虑到对无人值守的高标准要求，将设备网分为上层DH+和下层DH-485两级网络，以达到分散危险，提高网络有效性和可靠性的目的。
2） 经济性考虑，满足基本要求的前提下，采用低成本的微型PLC替代。干燥器设备的生产工艺相对较简单，控制点数不到10点，模拟量信号输入点数也不多，动态响应的时间常数相对较大，微型PLC——Micrologix 1200可以满足要求。其成本可降低一半，每套约节省2万元，计可达15万。
分级网络的特点：
transparent factory" without the need for large-scale automation transformation. The digital transformation solution integrates multiple modules such as order management, operation guidance management, execution and traceability management, real-time performance, task, response management, etc., and connects all
s of production and operation of Hanwei Technology. After the transformation, all kinds of data generated in the entire production and operation process of Hanwei Technology are clearly visible, providing a qualitative leap for the production and operation of personnel at all levels. Order management system: It makes it easy for factories to manage production orders in real time. At each operation, the system will scan each product in each work order and record various relevant information in a timely manner. This enables managers to know the process status of each product, the completion progress of orders, exceptions and delivery expectations, and master the capacity resource allocation of the entire production line. Operation instruction management module: to achieve foolproof and error proof, as long as workers scan the barcode of the workpiece, the system will automatically push the operation instructions of the station to the board in front of the employees, which can guide employees to work very directly and quickly to avoid human errors. Immediate performance, task and response management module: once abnormal conditions occur on the production line, workers can immediately alarm through the light on system, and the system will automatically notify the relevant maintenance personnel to deal with them until the fault is removed. The system automatically records the fault type, time of occurrence, time of fault resolution, and personnel information, and serves as the data basis for post statistics and analysis, as well as the basis for the assessment of relevant personnel, so as to achieve accurate management of responsibilities and KPIs. Execution and traceability management module: realize closed-loop precise traceability, bind individual products accurately on materials, products, employees, stations and other information, and record them by the system. Once there is a problem with the product or raw material, you can quickly locate the corresponding raw materials, personnel information, or the affected product batch and customer range to provide information support for analyzing the problem and reducing customer losses. In addition, the lean experts of Electric also made some specific lean improvements to the production line of Hanwei Technology. For example, the original single station production mode was changed to L-shaped and U-shaped unit production lines, allowing employees to achieve the coordination of production rhythm through division of labor, virtually reducing the efficiency shortfalls caused by individual differences of employees.
Customer benefits Supported by transparent processes and data, Hanwei Technology has made a qualitative leap in the granularity and visualization of production management. It can grasp the production status every week, every day and even every hour at any time, so that it can quickly respond to the challenges brought by various changes, and even make response decisions in advance. Three months after the transformation, the production efficiency of Hanwei Technology's production line has increased by 12%, the production capacity has increased by 22%, the per capita output value has increased by 14%, and the failure rate fed back by the market has decreased by 25%. In addition, by ing the KPI information of production with salary and career development, the enthusiasm of employees has also been improved qualitatively. With the help of Electric lean experts, the staff team of Hanwei Technology has also mastered the ability of independent improvement and become a "fresh force" for continuous improvement, laying a solid foundation for Hanwei Technology's sustainable development in the Internet of Things industry. System parameters can be set quickly and easily in the software.
