 PLC程序設計優(yōu)良與否的幾個評價重點指標

（1）PLC程序的正確性。

正確的程序能經(jīng)得起系統(tǒng)出運行實踐的考驗。

（2）PLC程序的可靠性。

●能保證系統(tǒng)在正常和非正常（短時掉電、某些被控量超標、某個環(huán)節(jié)有故障等）情況下都能可靠地運行。

●能保證在出現(xiàn)非法操作（如按動或誤觸動了不該動作的按鈕等）情況下不至于出現(xiàn)系統(tǒng)失控。

（3）PLC參數(shù)的易調(diào)整性好。

經(jīng)常修改的參數(shù)，在程序設計時考慮怎樣編寫才能易于修改。

（4）PLC程序結構簡練。

簡練的程序，可以減少程序掃描時間、提高PLC對輸入信號的響應速度。

（5）PLC程序的可讀性好。
