    HITACHI LYD000A工控卡件,LYD000A使用尺寸

    例如,如果用戶正在輸入

    將值9和%R150相加,則過程為:1.從PLC編程軟件中,選擇“參考表”(F2)。

    2.將光標指向將包含撥號字符串的每個%R,并選擇“ascii”(F7)格式。

    3.選擇%R150并鍵入“9”(包括引號)。點擊“回車”鍵,將值輸入到適當的寄存器。

    對于剩余的撥號字符串,請遵循此過程。如果使用PLC編程軟件以十六進制格式輸入撥號字符串,則選擇“十六進制”(F5)并將寄存器組轉換為十六進制格式。然后,每個撥號字符串都將是根據ASCII等效輸入,不需要引號。詳見第22頁附錄AASCII/十六進制轉換圖。

    HITACHI LYD000A工控卡件使用HHP,只能以十六進制格式輸入撥號字符串。只需轉到%R150并輸入連續寄存器中十六進制格式的撥號字符串。有關詳細信息,請參見表3-6、3-7和3-8特殊撥號字符串的配置示例和第23頁的附錄B。注意:表盤字符串從右到右輸入PLC編程軟件和手持式編程器

    左邊示例:數字“1”后跟“2”將輸入這兩個設備“3231”一旦撥號字符串輸入到適當的寄存器中,則第一個離散輸出(%Q)為HE693RTU940配置,切換以啟動呼叫。在寄存器中輸入“1”將調用撥號撥號%R引用處的字符串,在我們前面的示例中,%R150。將“0”輸入寄存器清除狀態寄存器并斷開呼叫。

    一旦將%Q設置為高并且撥打了電話號碼,則會顯示“異常報告”命令采樣以查看呼叫是否被接受。如果呼叫被接受,主機將發出Modbus請求然后,主機將在預定位置請求數據。當主人

    掛斷,本地調制解調器將丟棄載波檢測(DCD),從機將設置狀態OK(%I8)。這個每次命令完成時,連接都會斷開。調制解調器無法保持連接。

    For example, if the user was entering 

    the values 9 and , into %R150, then the process would be:

    1. From the PLC Programming Software, select 'Reference Tables' (F2).

    2. Cursor to each %R that will contain dial string characters and select 'ascii' (F7) format.

    3. Select the %R150 and type "9," (include quotation marks). Strike the 'Enter' key to input the values to 

    the appropriate registers.

    Follow this process for the remaining dial string.

    If entering the dial string in hexadecimal format using the PLC Programming Software, then select 'hex' 

    (F5) and convert the group of registers to a hexadecimal format. Each dial string character would then be 

    entered according to it's ASCII equivalent, no quotation marks needed. See Appendix A on page 22 for 

    an ASCII/HEX conversion chart. 

    Using the HHP, the dial string can only be entered in hexadecimal format. Simply go to %R150 and enter 

    the dial string in the consecutive registers in hexadecimal format. See Tables 3-6, 3-7, and 3-8 for 

    Configuration Examples and Appendix B on page 23 for Special Dial String Characters. Note: The dial 

    string is entered into the PLC Programming Software and the Hand Held Programmer from right to 

    left. Example: The number "1" followed by "2" would be entered into these two devices, "3231."Once the dial string has been entered into the appropriate registers, then the first discrete output (%Q) 

    configured for the HE693RTU940 is toggled to initiate a call. Entering a '1' into the register calls the dial 

    string at the Dial %R reference, in our previous example, %R150. Entering a '0' into the register clears 

    the status register and disconnects the call. 

    Once the %Q has been set high and the telephone number dialed, the Report-By-Exception command is 

    sampled to see if the call was accepted. If the call was accepted, the Master will issue a Modbus request 

    for the station ID. The Master will then request data at a predetermined location. When the Master 

    hangs up, the local modem will drop the Carrier Detect (DCD) and the slave will set status OK (%I8). The 

    connection is broken each time a command is completed. The modems do not stay connected.
