介紹一個(gè)比較典型的規(guī)模比較大的MODBUS通訊的項(xiàng)目,2013年做的。
甲方已經(jīng)運(yùn)轉(zhuǎn)的一批14套單機(jī)設(shè)備,都是S7-200PLC控制的,后來(lái)為實(shí)現(xiàn)能源優(yōu)化管理,想加上電度表,加上WINCC*監(jiān)控,以監(jiān)控設(shè)備在每一生產(chǎn)環(huán)節(jié)的能耗情況。
zui初報(bào)的方案是買485接口的電能表,通過(guò)S7-200的空閑的一個(gè)通訊口接入到PLC(另一個(gè)通訊口被KTP觸摸屏占用),然后每臺(tái)PLC再增加一個(gè)CP243-1,通過(guò)光纖以太網(wǎng),接入到車間辦公室的WINCC。同時(shí)還增設(shè)了IP攝像頭,也同樣走此以太網(wǎng)線路。
因?yàn)槊颗_(tái)設(shè)備具體細(xì)節(jié)還有不一樣,到具體設(shè)計(jì)的時(shí)候,竟然才發(fā)現(xiàn),有2個(gè)柜子,CPU的I/O模塊已經(jīng)達(dá)到7個(gè)模塊,無(wú)法再擴(kuò)展CP243-1模塊了。
所以臨時(shí)改變?cè)O(shè)計(jì),改為:每套設(shè)備,增加串口服務(wù)器,以太網(wǎng)轉(zhuǎn)換為RS485串口,并作為MODBUS MASTER,下掛2個(gè)從站,分別是電能表和S7-200. 上位使用KEP SERVER軟件,讀取到每一個(gè)串口服務(wù)器,每一個(gè)電能表或者CPU作為一個(gè)設(shè)備單元。
