5069-L306ER/ABPLC拆機(jī)件
200PLC組成的RS485通信網(wǎng)絡(luò)其大通信距離為500米,可掛接32個節(jié)點(diǎn),距離超過500米時需在RS485總線上加裝RS485中繼器,為方便接線,每個PLC的通信端口需安裝總線連接器,網(wǎng)絡(luò)的兩端需配接終端電阻。這是一種常規(guī)的通信方案,有以下幾個缺點(diǎn):
1、當(dāng)距離超過500米時,需增加RS485中繼器來延長通信距離,而中繼器需要供電,這對于有些無供電條件的場合,如野外、油田、海底等將帶來很大煩。
2、整個通信網(wǎng)絡(luò)是非隔離的,抗*力較差,特別是當(dāng)網(wǎng)絡(luò)上連接有變頻器通信時容易造成誤碼和死機(jī)。
3、由于通信網(wǎng)絡(luò)是非隔離的,當(dāng)有雷電或其它較強(qiáng)的瞬變電壓干擾作用于網(wǎng)絡(luò)上時勢必造成網(wǎng)絡(luò)上的全部PLC損壞,帶來重大的損失!
采用德陽四星電子研制PFB-G總線隔離器或CAN-485G遠(yuǎn)程驅(qū)動器可以很好的解決以上問題:
