新開發(fā)的運(yùn)動(dòng)單元，甚至還發(fā)行了NC技術(shù)的編程語言，為更好地用PLC進(jìn)行數(shù)字控制提供了方便。
3.4用于數(shù)據(jù)采集
隨著PLC技術(shù)的發(fā)展，其數(shù)據(jù)存儲(chǔ)區(qū)越來越大。如德維森公司的PLC，其數(shù)據(jù)存儲(chǔ)區(qū)（DM區(qū)）可達(dá)到9999個(gè)字。這樣龐大的數(shù)據(jù)存儲(chǔ)區(qū)，可以存儲(chǔ)大量數(shù)據(jù)。
數(shù)據(jù)采集可以用計(jì)數(shù)器，累計(jì)記錄采集到的脈沖數(shù)，并定時(shí)地轉(zhuǎn)存到DM區(qū)中去。
數(shù)據(jù)采集也可用A/D單元，當(dāng)模擬量轉(zhuǎn)換成數(shù)字量后，再定時(shí)地轉(zhuǎn)存到DM區(qū)中去。
PLC還可配置上小型打印機(jī)，定期把DM區(qū)的數(shù)據(jù)打出來。
PLC也可與計(jì)算機(jī)通訊，由計(jì)算機(jī)把DM區(qū)的數(shù)據(jù)讀出，并由計(jì)算機(jī)再對這些數(shù)據(jù)作處理。這時(shí)，PLC即成為計(jì)算機(jī)的數(shù)據(jù)終端。
