T-1A53362-4S 高、中檔的PLC，還開發(fā)有NC單元，或運(yùn)動(dòng)單元，可實(shí)現(xiàn)點(diǎn)位控制。運(yùn)動(dòng)單元還可實(shí)現(xiàn)曲線插補(bǔ)，可控制曲線運(yùn)動(dòng)。所以，若PLC配置了這種單元，則完全可以用NC的辦法，進(jìn)行數(shù)字量的控制。
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。
1.3.4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OMRON公司的PLC，前期產(chǎn)品C60P的DM區(qū)僅64個(gè)字，而后來的C60H達(dá)到1000個(gè)字；到了CQMI可多達(dá)6000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(duì)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。
電業(yè)部門曾這么使用PLC，用以實(shí)時(shí)記錄用戶用電情況，以實(shí)現(xiàn)不同用電時(shí)間、不同計(jì)價(jià)的收費(fèi)辦法，鼓勵(lì)用戶在用電低谷時(shí)多用電，達(dá)到合理用電與節(jié)約用電的目的。
