PLC应具有的特和优势:
更高的处理能力;
的运行稳定可靠;
强大的网络通信能力,能完成多系统间以及控制级与设备、上级管理层大数据通信需求;
具有更强的鲁棒,适应更加苛刻的运行环境要求;
具有更快的(如千兆Gb)以太网,实现高速现场设备的轮询和数据管理;
控制器功能经过优化,大程度地提高系统能;
提供更强的诊断与故障处理能力,更强的安全,更丰富的功能;
二、PLC能从多方面增强控制系统:
智能
提供更强的诊断和故障处理功能;
基于以太网集成运动控制,轴数可达128-256;
集成以太网处理能力,实现高能的通信;
通过更好的通信能力,支持对现场设备大数据的采集和处理需求;
提供可选非易失存储器,可将用户程序和标签数据存储在控制器中;
用先进的技术取代数据备份所必需的电池或储能模块等易损耗器件;
配套软件的编程和组态环境可简化系统开发和调试。
提供额外的物理安全防护;
固件采用数字签名并进行加密,有助于防范企图;
可对尝试访问系统的进行身份验证,实现集中式身份验证和访问控制。
