    RELIANCE 57C493自動化模塊

    AOUT_功能塊轉換功能塊互連信號,連接到輸入S,連接到a具有范圍為4-20 mAdc的塊輸出。輸入D可用于斷開輸出與斷言為高(1)時的負載。此功能非常有用當兩個或多個控制器連接到公共負載。當一個控制器連接到使用斷開功能。功能塊包括:通過塊縮放至4-20 mA輸出范圍輸入信號。范圍指針參數(輸入R)告訴塊從何處獲取縮放信息。

    如果未配置此參數,則塊將:使用0.00到100.00的范圍。上有兩個模擬輸出功能塊:

    控制器板和擴展器板。功能塊名稱和終端標識如下所示。輸出是工廠的校準為4-20 mAdc,不需要現場校準。但是,如果出現以下情況,可以進行現場校準渴望的通過調整脈沖發生器校準輸出,直到獲得所需輸出(即,0為4.0 mA)然后按下存儲按鈕。校準期間,驗證模式可用,將在中顯示mA值數字顯示,脈沖發生器在整個范圍內調整輸出。

    輸出QS是質量狀態輸出

    如果輸出驅動器檢測到高阻抗或開路,它將變高環行字母數字將閃爍AOUT_。當檢測到開路情況時為OC。QS輸出可以也可用于在冗余應用中切換到第二輸出電路。固件1.30及更高版本中的ATD_塊可用作在循環中需要(每個循環最多5個),以趨勢連接到輸入A的模擬變量。塊可以存儲最多170個數據點,具體取決于啟用/禁用功能(見下文)。趨勢可能是使用Modbus命令顯示。可以檢索數據并由遠程操作員站顯示,并顯示來自該站的數據分組。個人電腦或運行i|ware PC操作員界面軟件的I124Station可以在回路詳細信息屏幕或模擬詳細信息上顯示趨勢數據屏幕參數TRND TYP允許將數據存儲在兩種格式:每個采樣時間的平均值或每個采樣時間內數據的峰值/峰值。全部的基于RG PTR(范圍指針)輸入。范圍信息將:在通過網絡檢索時成為數據包的一部分通信。未配置此輸入時,范圍將使用0.0-100.0。

    AOUT_ function blocks convert function block

    interconnection signals, connected to input S, to a

    block output having a range of 4-20 mAdc. Input

    D can be used to disconnect the output from the

    load when asserted high (1). This feature is useful

    when two or more controllers are connected to a

    common load. When one controller is connected to

    the load, others are disconnected using the

    disconnect feature. The function block includes

    scaling to range the 4-20 mA output with the block

    input signal. The range pointer parameter (input R)

    tells the block where to obtain scaling information.

    If this parameter is not configured the block will

    use a range of 0.00 to 100.00.

    Two analog output function blocks are available on

    the Controller Board and one additional on the

    Expander Board. Function block names and terminal identifications are listed below. The output is factory

    calibrated for 4-20 mAdc and should not require field calibration. However, field calibration can be performed if

    desired. The output is calibrated by adjusting the pulser until the desired output (i.e. 4.0 mA for zero) is obtained

    and then pressing the store button. A verify mode is available during calibration that will show the mA value in the

    numeric display as the pulser adjusts the output over the full range.

    Output QS is the Quality Status output. It will go high if the output driver detects a high impedance or an open

    circuit. The alphanumeric will flash AOUT_.OC when an open circuit condition is detected. The QS output could

    also be used to switch to a second output circuit in a redundancy application. ATD_ blocks, in firmware 1.30 and higher, can be used as

    needed in loops (up to a maximum of 5 per loop) to trend an

    analog variable connected to input A. The block can store

    up to 170 data points depending upon the use of the

    enable/disable function (see below). A trend can be

    displayed using Modbus commands. Data can be retrieved

    and displayed by a remote operator station that can retrieve,

    interpret, and display data packets from the station. A PC or

    i|station running i|ware PC operator interface software can

    display trend data on a Loop Detail screen or Analog Detail

    screen.

    Parameter TRND TYP allows data to be stored in one of

    two formats: the average over each sample time or the

    peak/peak values of the data over each sample time. All

    data is stored in a normalized form based on the value of the

    RG PTR (range pointer) input. The range information will

    be part of the data packet when retrieved over the network

    communications. When this input is unconfigured, a range

    of 0.0 - 100.0 will be used.
