然而,在PAC刚刚开始拓展其应用面的新产品时,还不被大多数用户认识和认可。在用户和系统集成商之间,对于PAC的批评声也不绝于耳。有人说,PAC相对于PLC来说价格高、可靠性低、可扩展能力差;还有人认为,PAC并没有真正针对某种迫切的或潜在的市场需求,因此不免曲高和寡。
PAC与PLC的区别
PAC与PLC根本的不同在于它们的基础不同。PLC的性能依赖于的硬件,PLC的应用程序是依靠的硬件芯片来实现的。对于PLC功能的改进,如增加运动控制、过程控制或通信能力,都需要使用不同的硬件。即使对于同一PLC厂家,这种的硬件也很难移植到不同性能的PLC中,而且传统的PLC厂家的硬件结构体系都是专有的,甚至于处理器芯片都是的芯片,这样就导致了随着PLC功能需求的不断提高,PLC的硬件体系变得越来越复杂,而且由于硬件的非通用性会导致系统的功能前景和可开放性受到很大的限制,这也是为什么PLC的CPU的性能通常比PC机的CPU要落后得多的原因。另外,PLC的操作系统通常都是各PLC厂家的操作系统,与目前流行的实时操作系统不兼容,由于是的操作系统,其实时可靠性与功能都无法与通用的实时操作系统相比,这就使得PLC具有了整体性能的性和封闭性。
