 定時(shí)器，可進(jìn)行定時(shí)控制。定時(shí)值可任意設(shè)定。定時(shí)器有多少，設(shè)定范圍有多大，設(shè)定值的分辨率又是多少，這些都代表定時(shí)器件的性能。 

   計(jì)數(shù)器，可進(jìn)行計(jì)數(shù)，到達(dá)某設(shè)定計(jì)數(shù)值可發(fā)送相應(yīng)信號。可進(jìn)行什么樣的計(jì)數(shù)，計(jì)數(shù)范圍多大，怎么設(shè)定，有多少計(jì)數(shù)器，則是PLC計(jì)數(shù)器性能的代表指標(biāo)。 

   數(shù)據(jù)存儲區(qū)，用以存儲工作數(shù)據(jù)。多以字、兩字或多字為單位予以使用，是PLC進(jìn)行模擬量控制，或記錄數(shù)據(jù)所必不可少的。這個(gè)存儲區(qū)的大小代表PLC的性能也是越大越好。趨勢也是越來越大。小型機(jī)也如此。如日本OMRON公司的CQM1機(jī)，其DM區(qū)就有6k字。而過去同是小型機(jī)的C60P的DM區(qū)才64個(gè)字。大型機(jī)的DM可達(dá)10K以至幾十K。 備貨，備貨，降降降，火火火，火火火……
