■ Output Dat輸出數(shù)據(jù)
The output data is a numeric data value that is written out of a function block via an output terminal.輸出數(shù)據(jù)是通過一個輸出端子從一個功能塊寫出的數(shù)字值。
The types of output data are shown below:以下是輸出數(shù)據(jù)的幾種類型：
• Manipulated output value (MV)
• Auxiliary output values (PV, _PV, MV, _MV)輔助輸出值A(chǔ)ST143-S00/ST4S0
• Process variable (PV)
● Manipulated Output Value (MV)操作輸出值
▼ MV Display Style顯示類型
Use the Function Block Detail Builder to set the display b for the manipulated output value (MV).通過功能塊的Detail Builder設(shè)置MV的顯示形式AST143-S00/ST4S0。
• MV Display Style:顯示類型
Select “Automatic Determination” or “User Define.
The default is “Automatic Determination.” ”選擇“自動設(shè)定”和“用戶自定義”。缺省為“自動設(shè)定”。
When “Automatic Determination” is selected, the engineering unit and scale range of the manipulated output value (MV) change according to the connected destination of the OUT terminal.當“自動設(shè)定”被選中，MV值的工程單位和量程依照輸出端子連接目標而變化。
• If the connection destination is a process I/O, the scale range and engineering unit of the manipulated output value (MV) is fixed to “0 to
• When outputting to a cascade setpoint value (CSV) in a case where the connection destines to a SET terminal of another function block (cascade connection), the engineering unit and scale range of the manipulated output value (MV) agree with those of the cascade setpoint value (CSV) of the output destination.
When the connection destination is an b terminal of another function block than SET terminal, “self determination” must be selected. 當輸出到一個串級設(shè)定值(CSV)，并且指定連接為另一個功能塊的設(shè)定值輸入端（SET），MV的工程單位和量程同CAS的指定輸出連接相匹配。 當指定連接是另一個模塊的輸入端時，“自設(shè)定”必須被選中AST143-S00/ST4S0。
When “User Define” is selected, set the engineering unit and scale range for the manipulated output value (MV).當用戶自定義選中時，設(shè)置MV的工程單位和量程
• MV Engineering Unit Symbol:MV工程單位標記
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(jié)組成，缺省為：“％”
• MV Range:MV范圍
High and low limits.高低限：
Numerical values of seven digits or less, where the sign and decimal point occupy one digit each.
