AsSCADAis toHMI, the Programmable Automation Controller(PAC) is to the Programmable Logic Controller (PLC). Just like the PAC can do everything the PLC can do, the SCADA software system can do everything that the HMI can do; the PAC can do everything the PLC does. However, just like ...
PAC stands forProgrammable Automation Controller, which is similar to a PLC but has more advanced functionality. PAC combines the capabilities of a traditionalPLCwith the ability to perform much more complicated tasks and communicate with other devices and systems, making them more flexible and powerfu...
The article discusses several issues to consider when choosing between a programmable logic controller (PLC) and a programmable automation controller (PAC) for a particular application. It is said that PLCs have been best fitted for machine control, both simple and high speed. It was noted that...
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。 不管怎样,目前PLC仍然是用户和系统集成商的首选控制器。 许多工业用户认为PLC简单适用、价格低廉、稳定可靠,大概可以满足80%的工业控制要求。 其实早在20世纪90年代中期,PLC技术...
