國產(chǎn)PLC可編程控制器控制系統解決方案 USC-8000 軟件-通信軟點(diǎn)丨龍鼎源

USC-8000系統支持使用串口、以太網(wǎng)口作為MODBUS從站通訊,將內部的數據傳輸至HMI軟件或第三方設備。與第三方交互的數據必須為全局變量。

工程創(chuàng )建完畢后,點(diǎn)擊“Solution Explorer”下的“Global Variables”,創(chuàng )建一個(gè)全局變量,創(chuàng )建該全局變量時(shí),不需要設置變量地址。目前,USC-8000系統支持配置3種類(lèi)型的全局變量,分別為BOOL型、INT型和REAL型。例如,設置的全局變量名稱(chēng)為a,數據類(lèi)型為BOOL型,該變量可讀/寫(xiě),地址暫時(shí)為空。


右鍵點(diǎn)擊“SOC”,選擇“HardwareConfigure”,雙擊已配置完畢的COMM模塊,彈出“VariablesConfigure”界面,界面如下所示


“VariablesConfigure”界面,用戶(hù)可以設置全局變量a的地址,其中,BOOL型全局變量的地址范圍:50000~50255,REAL型全局變量的地址范圍:60000~60143,INT型全局變量的地址范圍:60000~60144,因此,可將全局變量a的地址設置為50000,點(diǎn)擊“Enter”,保存設置。

用戶(hù)設置完畢后,Workbench軟件的全局變量列表“SOC-VAR”,會(huì )顯示設置成功的變量地址,如下圖所示,全局變量a的地址為c350,目前,Workbench軟件上顯示的地址數據,均為16進(jìn)制。
