他们认为,未来嵌入式技术将会被广泛应用于PAC,成为自动化系统的重要技术之一。
在用户和系统集成商之间,对于PAC的质疑同样存在:PAC相对于PLC来说价格高、可靠性低、可拓展能力差,还有人认为,PAC并没有真正针对某种迫切的或者潜在的市场需求,因此不免曲高和寡。
有部分反对者则认为,PAC技术发展趋向,如统一的多专业开发平台、通信技术等也会对PLC的技术发展施加有益的影响。
值得一提的是,除了上述提到的PLC、PC-Based和PAC之外,针对行业应用,机器人专用控制器成为国内多数厂商布局的重点,特别是像埃斯顿、华中数控、配天机器人等这样以机器人本体研发为主的企业。
目前,随着大规模和超大规模集成电路等微电子技术的发展,PLC已由初一位机发展到现在的以16位和32位微处理器构成的微机化PC,而且实现了多处理器的多通道处理。如今,PLC技术已非常成熟,不仅控制功能增强,功耗和体积减小,成本下降,可靠性提高,编程和故障检测更为灵活方便,而且随着远程I/O和通信网络、数据处理以及图象显示的发展,使PLC向用于连续生产过程控制的方向发展,成为实现工业生产自动化的一大支柱。如今在各个行业的智能制造时代,PLC技术的发展呈现出产品规模两极发展、通信网络化、模块化与智能化、编程语言/工具的多样化和标准化等新的特点,并与新兴技术结合,将进一步赋能数字化企业和智能工厂。
