初學(xué)西門(mén)子200 PLC，想與多塊稱(chēng)重儀表進(jìn)行MODBUS通訊，就是PLC是主站，多個(gè)稱(chēng)重儀表是從站，一主多從的通訊方式，稱(chēng)重儀表與模擬拉力傳感器連接，目前我知道的只有梅特勒托利多的稱(chēng)重顯示儀表帶有MODBUS通訊選件，但是價(jià)格太貴，一塊顯示儀表要8千左右，負擔不起。不知道其他廠(chǎng)家的或者國產(chǎn)的稱(chēng)重顯示儀表有沒(méi)有帶MODBUS通訊的？或者是帶RS232串口通訊的顯示儀表用自由口編程也能實(shí)現類(lèi)似于MODBUS通訊“一主多從”的功能嗎？

準備也用儀表和200MODBUS通訊
技術(shù)在于積累，學(xué)習在于堅持。
