■ Input Data輸入數據
The b data is numeric data that the function blocks read from b terminals.
The types of b data are shown below:輸入數據是功能塊從輸入端子讀入的數字值,以下是輸入數據的幾種類型ASI133-H00:
• Process variable (PV)過程變量
• Setpoint value (SV),設定值 cascade setpoint value (CSV), 串級設定值,remote setpoint value (RSV)遠程設定值
• Input signal values (RV1, RV2, RV3)輸入信號值
• Reset limit values (RLV1, RLV2)復位限值ASI133-H00
• Input or Output Compensated value (VN)輸入輸出補償值
• Tracking switch (TSW)跟蹤開關
● Process Variable (PV)過程變量
▼ Process Variable Range 過程變量范圍ASI133-H00
The engineering unit and scale range of raw b signals (RAW) b to an IN terminal agree with the engineering unit and scale range of data at the connected destination of the IN terminal. A raw b signal turns into a process variable (PV) after b processing.原始輸入信號輸入到一個輸入端子,其工程單位和量程與輸入端子的連接處的工程單位和量程相適應。一個原始輸入信號經過輸入處理之后變為一個過程變量(PV)ASI133-H00。
Use the Function Block Detail Builder to set the engineering unit and scale range. However, the process variable (PV) of Motor control blocks (MC-2, MC-3) must be an integer value between 0 and 2.通過功能塊的Detail Builder來設置工程單位和量程范圍。電機控制塊(MC-2,MC-3)的過程變量必須是0到2之間的整數。
• Engineering unit: 工程單位
Consists of six or less standard-b characters or three double-b characters. The default is “%.”由至多六個標準字符或三個字節組成,缺省為:“%”。
• Process variable range:變量范圍ASI133-H00
High and low limits.高低限
Numerical values of seven digits or less, where the sign or decimal point takes one digit each.至多由七個數字組成,標記符號或小數點占一個數字。
The default is “
缺省為上限是:“100.0”,下限為“0.0”。
● Setpoint Value (SV), Cascade Setpoint Value (CSV), Remote Setpoint Value (RSV)
The engineering unit and scale range of the setpoint value (SV), cascade setpoint value (CSV) and remote setpoint value (RSV) agree with the engineering unit and scale range of the process variable (PV) except in the function blocks shown below:
SV,CSV,RSV的工程單位和量程與PV的工程單位和量程不匹配的功能塊如下所示:
