如何選購PLC產(chǎn)品呢?
1、系統(tǒng)規(guī)模首先應(yīng)確定系統(tǒng)用PLC單機(jī)控制,還是用PLC形成網(wǎng)絡(luò),由此計(jì)算PLC輸入、輸出點(diǎn)。數(shù),并且在選購PLC時要在實(shí)際需要點(diǎn)數(shù)的基礎(chǔ)上留有一定余量(10%)。
2、確定負(fù)載類型根據(jù)PLC輸出端所帶的負(fù)載是直流型還是交流型,是大電流還是小電流,以及PLC輸出點(diǎn)動作的頻率等,從而確定輸出端采用繼電器輸出,還是晶體管輸出,或品閘管輸出。不同的負(fù)載選用不同的輸出方式,對系統(tǒng)的穩(wěn)定運(yùn)行是很重要的。
3、存儲容量與速度盡管國外各廠家的PLC產(chǎn)品大體相同,但也有一定的區(qū)別。目前還未發(fā)現(xiàn)各公司之間完全兼容的產(chǎn)品。各個公司的開發(fā)軟件都不相同,而用戶 程序的存儲容量和指令的執(zhí)行速度是兩個重要指標(biāo)。一般存儲容量越大、速度越快的PLC價格就越高,但應(yīng)該根據(jù)系統(tǒng)的大小合理選用PLC產(chǎn)品。
