Although there are many similarities between PLCs and PACs,there are still some key differences between them.Most of these differences are related to high-end features.In some very large and complex applications,a PAC system may be required due to the number of instruments,remote equipment,extensive process control and monitoring and other requirements.These differences are generally related to hardware configuration,expansion capabilities,and costs.

尽管在PLC和PAC之间有很多相似点，它们之间仍然有一些关键差异。这些差异大多与高端功能相关。在某些超大型和复杂的应用场合，由于仪表数量、远程设备、大量的过程控制和监视等其它方面的需求，可能需要使用PAC系统。这些差异一般与硬件配置、扩展功能以及费用等相关
