PR6423/00R-010 CON021 传感器PAC目前锁定的最大应用领域仍是工控，而来自工厂的实时数据可以令管理阶层拥有更丰富的信息资源，以便借此进行决策，但是要安装能够提供工厂数据的系统可能相当困难。企业系统通常会通过ODBC、ADO及XML等标准输入来自自动化系统的数据。PLC的做法是通过OPC之类的标准提供通信能力，也就是说，必须加入PC才能使用OPC来取得数据，并且使用ODBC、ADO和刀ilL之类的标准将数据反馈给企业。而PAC可 以有效地将工厂数据整合至ERP系统中，让控制系统能够直接和外部数据库通信。而当控制系统连接至数据库及网站时，安全性的问题开始出现。为了获得最高的安全性，许多厂商选择不要将自动化系统与企业连接。但是大致上来说，连接的优点远超过安全问题，虽然PLC可以保护它不被工厂的入侵者偷窃，但是PLC难以对抗以以太网络连接端口未受保护封包为目标的黑客。

PAC可以在利用网络传输数据之际进行编码，因此而保护资料。虽然这在今天可能不是关注的焦点，但是在将来，它可能会是影响PAC进驻工厂的主要因素。一机多用节省成本。就成本配置来看，在小型的数字控制应用中，控制器的价格可能比VO模块的价格更高。对这些应用环境而言，一个仅控制数字VO线路的微型PLC可能是理想 的解决方案。但是，如果系统需要视觉或仪器控制，就必须为这些功能另外购置独立的控制器。PLC控制器并非为了仪器控制所需的高速模拟νo或视觉应用所需的高速数据传输速度而设计，因此PLC没有视觉或仪器控制模块，必须为这些应用配置独立的控制器，从而提高成本。而以PAC的状况来看，一部控制器和机架就可以处理数字及模拟VO、动作、视觉及仪器，因此节省多部控制器的费用，每当控制系统需要多重功能时， PAC相比之下成本最低。

The PR6423/00R-010 CON021 sensor PAC is currently locked in the largest application field of industrial control, and real-time data from factories can provide management with richer information resources for decision-making. However, installing a system that can provide factory data may be quite difficult. Enterprise systems typically input data from automated systems through standards such as JDBC, ADO, and XML. The approach of PLC is to provide communication capability through standards such as OPC, which means that a PC must be added in order to use OPC to obtain data, and standards such as ODBC, ADO, and knife ilL are used to feedback data to the enterprise. PAC can effectively integrate factory data into ERP systems, allowing control systems to communicate directly with external databases. When the control system connects to the database and website, security issues begin to arise. In order to achieve the highest level of security, many manufacturers choose not to connect automation systems to the enterprise. But generally speaking, the advantages of connection far outweigh security issues. Although PLC can protect it from theft by factory intruders, it is difficult for PLC to resist hackers targeting unprotected packets on Ethernet connection ports.

PAC can encode data while utilizing the network for transmission, thus protecting data. Although this may not be the focus of attention today, in the future, it may be the main factor affecting PAC’s entry into factories. Multi use of one machine saves costs. In terms of cost allocation, in small-scale digital control applications, the price of controllers may be higher than that of VO modules. For these application environments, a micro PLC that only controls digital VO circuits may be an ideal solution. However, if the system requires visual or instrument control, separate controllers must be purchased for these functions. PLC controllers are not designed for high-speed simulation required for instrument control ν Designed for the high-speed data transmission speed required for visual applications, PLCs do not have visual or instrument control modules, and independent controllers must be configured for these applications to increase costs. From the perspective of PAC, a single controller and rack can handle digital and analog VO, motion, vision, and instruments, thus saving the cost of multiple controllers. Whenever the control system requires multiple functions, PAC has the lowest cost compared to others.
