数量——对于装备制造厂商而言，单一装备（同样的硬件配置和程序）月生产量500台以下就可以考虑使用PLC，如果超过了这个数量就可以考虑使用专用PLC或者单片机开发的专用控制器。
品牌——各成熟厂商PLC的功能差别不大，品牌的选择更多的是考虑服务和宣传，这需要装备制造厂商根据自己的定位来选择，但品牌在PLC的价值中占有较大有份额，同样点数，同样功能的PLC，不同品牌的价格会有数倍至十倍的差别。
功能——功能的选择不是越多越好，许多功能大多数用户都用不上，但是有一些功能又是PLC的可选功能，比方说实时时钟、电池、RS485、扩展接口等，一般基本功能的PLC价格会很低，但如果选择增加功能价格就会高很多。
