只怕不勤,不怕不精;只怕無恒,不怕無成。
PLC控制系統(tǒng)一般設(shè)計方法:
1、分析控制系統(tǒng)的控制要求
熟悉被控對象的工藝要求,確定**完成的動作及動作完成的順序,歸納出順序功能圖。
2、選擇適當類型的PLC
根據(jù)生產(chǎn)工藝要求,確定I/O點數(shù)和I/O點的類型(數(shù)字量、模擬量等),并列出I/O點清單。
進行內(nèi)存容量的估計,適當留有余量。根據(jù)經(jīng)驗,對于一般開關(guān)量控制系統(tǒng),用戶程序所需
存儲器的容量等于I/O總數(shù)乘以8;對于只有模擬量輸入的控制系統(tǒng),每路模擬量需要100個存
儲器字;對于既有模擬量輸入又有模擬量輸出的控制系統(tǒng),每路模擬量需要200個存儲器字。
確定機型時,還要結(jié)合市場情況,考察PLC生產(chǎn)廠家的產(chǎn)品及其售后服務(wù)、技術(shù)支持、網(wǎng)絡(luò)通信
等綜合情況,選定性能價格比好一些的PLC機型。
