定时器,可进行定时控制。定时值可任意设定。定时器有多少,设定范围有多大,设定值的分辨率又是多少,这些都代表定时器件的性能。
计数器,可进行计数,到达某设定计数值可发送相应信号。可进行什么样的计数,计数范围多大,怎么设定,有多少计数器,则是PLC计数器性能的代表指标。
数据存储区,用以存储工作数据。多以字、两字或多字为单位予以使用,是PLC进行模拟量控制,或记录数据所必不可少的。这个存储区的大小代表PLC的性能也是越大越好。趋势也是越来越大。小型机也如此。如日本OMRON公司的CQM1机,其DM区就有6k字。而过去同是小型机的C60P的DM区才64个字。大型机的DM可达10K以至几十K。 备货,备货,降降降,火火火,火火火……
