1769-L37ERMOS/ABPLC拆機(jī)件
由于設(shè)備中對(duì)泵、電源、變頻器的要求較高。需要傳遞的參數(shù)和信息很多,且要根據(jù)工藝的變化作出實(shí)時(shí)的調(diào)整。故采用profibus總線的方式來實(shí)現(xiàn)需求。profibus通訊速度快高可到12m使用靈活(可根據(jù)gsd文件靈活選擇所需功能塊)支持從站數(shù)量多且應(yīng)用廣泛目前很多產(chǎn)品都支持該總線。
由于系統(tǒng)中profibus從站較多,所以選擇2dp類型的cpu,又由于對(duì)通訊速率,系統(tǒng)循環(huán)周期以及工作內(nèi)存等的要求較高故采用cpu317。
采用cp340通訊模塊來實(shí)現(xiàn)rs485通訊。分擔(dān)了cpu的一部分工作。提高了plc整體的工作效率,確保了通訊的可靠性。
