程序模擬調(diào)試

程序模擬調(diào)試的基本思想是，以方便的形式模擬產(chǎn)生現(xiàn)場實際狀態(tài)，為程序的運行創(chuàng)造必要的環(huán)境條件。根據(jù)產(chǎn)生現(xiàn)場信號的方式不同，模擬調(diào)試有硬件模擬法和軟件模擬法兩種形式。

1）硬件模擬法是使用一些硬件設備（如用另一臺PLC或一些輸入器件等）模擬產(chǎn)生現(xiàn)場的信號，并將這些信號以硬接線的方式連到PLC系統(tǒng)的輸入端，其時效性較強。公司  名稱：廈門泰尼電氣有限公司

2）軟件模擬法是在PLC中另外編寫一套模擬程序，模擬提供現(xiàn)場信號，其簡單易行，但時效性不易保證。模擬調(diào)試過程中，可采用分段調(diào)試的方法，并利用編程器的監(jiān)控功能。
