在工業(yè)生產(chǎn)中,人們常常面臨著數(shù)據(jù)采集與管理。作為工廠自動化的三大支柱可編程控制器PLC(Programmable Logic Controller),由于其安全可靠,廣泛的用于數(shù)據(jù)采集與控制。生產(chǎn)過程中,要監(jiān)視PLC內(nèi)部的數(shù)據(jù)與運(yùn)行狀況,選用市場上的人機(jī)界面或組態(tài)軟件,雖然功能豐富,但大都價格昂貴,在一些中小規(guī)模的生產(chǎn)場合,人們希望能自己用高級語言開發(fā)一個簡易實(shí)用的通信程序。微軟公司推出的Visual Basic 6.0,開發(fā)串行通信程序時,有兩種方法,一種是用Windows API函數(shù),另一種是用VB支持的通信控件MSCOMM.OCX。利用Windows API函數(shù)是通過調(diào)用讀寫等函數(shù)來操作串口。兩種比較,使用MSCOMM.OCX控件編程方便,具有更完善的發(fā)送和接收功能。這里采用了MSCOMM.OCX控件。
