HITACHI LYA210A模塊備件,LYA210A使用進展
本示例旨在利用“異常報告”功能從HE693RTU940發起調用。撥號%R參數從%R150開始配置。這被稱為is 123-4567。呼叫是在需要使用“9”at的建筑物內啟動的開始時的電話號碼，以訪問外部呼叫。因為本地交換需要
訪問外部線路時，必須輸入延遲，以允許正確的調制解調器響應。任何時候當地交換發生時，必須輸入延遲。必須從開始輸入的完整數字%R150為91234567。
HITACHI LYA210A模塊備件撥號%R參數是使用HHP的最后一個配置設置。設置直接輸入提示。使用HHP，只能以十六進制格式輸入撥號字符串。遵循上面的示例中，如果將撥號%R配置為%R150，則在參數提示。如果使用PLC配置軟件，撥號%R值150必須為從ASCII（十進制）轉換為二進制格式并輸入字節2。撥號字符串是撥號%R命令用于啟動呼叫的一組字符。示例撥打的電話號碼長度為9個字符。每個寄存器最多包含兩位數字。因此，撥號字符串（%R150-154）需要5個寄存器。
使用PLC編程軟件輸入撥號字符串有兩種方式：ASCII和十六進制。必須從編程菜單中選擇ASCII字段，并使用引號在輸入的每對撥號字符串值之前和之后使用。
This example is designed to originate a call from the HE693RTU940, taking advantage of the Report-ByException feature. The Dial %R parameter is configured beginning at %R150. The telephone number
that is called is 123-4567. The call is being initiated from within a building that requires the use of a '9' at
the beginning of telephone number to access outside calls. Because of the local exchange needed to
access outside lines, a delay must be entered to allow for proper modem response. Any time a local
exchange takes place, a delay must be entered. The complete number that must be entered beginning at
%R150 is 9,1234567.
The Dial %R parameter is the last configuration setting using the HHP. The setting is directly entered at
the prompt. Using the HHP, the dial string can only be entered in hexadecimal format. Following the
example above, if the Dial %R is to be configured at %R150, then the value 150 is entered at the
parameter prompt. If using the PLC Configuration Software, the Dial %R value of 150 has to be
converted from ASCII (decimal) to binary format and entered in
Byte 2.The dial string is a group of characters used by the Dial %R command to initiate a call. The example
telephone number being dialed is 9 characters in length. Each register holds a maximum of two digits.
Therefore, 5 registers are needed for the dial string (%R150 - 154).
Two ways are used to enter the dial string using the PLC Programming Software: ASCII and
hexadecimal. The ASCII field must be selected from the Programming menu and quotation marks have
to be used before and after each pair of dial string values entered.
