HONEYWELL FC-TSAI-1620M模擬量模塊,FC-TSAI-1620M使用在哪里
位0:錯誤極性。當該位為0時,誤差項為SP-PV。當此位為1,誤差項為PV-SP。將該位設置為1會修改標準PID誤差從正常(SP–PV)到(PV–SP)的術語,反轉反饋項。這適用于CV必須下降的反向作用控制當PV上升時。位1:輸出極性。當該位為0時,CV輸出表示PID計算。當設置為1時,CV輸出表示PID計算的輸出。將該位設置為1會反轉輸出極性該CV是PID輸出的負值,而不是正常的正值。
HONEYWELL FC-TSAI-1620M模擬量模塊位2:當該位為1時,從導數計算中刪除設定點。對于詳情見第15頁的討論。位3:死區動作。當死區動作位為0時,無死區動作已選擇。如果誤差在死區范圍內,則誤差為零。否則,誤差不受死區限制的影響。如果死區動作位為1,則選擇死區動作。如果誤差在死區極限時,誤差被迫為零。然而,如果錯誤是在死區極限之外,誤差由死區極限減小(誤差=錯誤–死區限制)。位4:防復位收卷動作。當該位為0時,反復位結束動作使用重置反向計算。當輸出被鉗制時,這將替換累積Y余數值,具有生成精確鉗位輸出。當位為1時,這將用Y項的值替換累積的Y項在計算開始時。這樣,預鉗位Y值保持的時間盡可能長當輸出被鉗位時。位5:啟用導數濾波。當該位設置為0時,不應用濾波導數項。當設置為1時,應用一階濾波器。這將限制導數項上的高頻過程干擾。可配置為128字增量,從128到帶DOS編程器的16384個字,來自128Windows程序員版本為32640字2.2或VersaPro 1.0版。
Bit 0: Error Polarity. When this bit is 0, the error term is SP - PV. When this bit is
1, the error term is PV - SP. Setting this bit to 1 modifies the standard PID Error
Term from the normal (SP – PV) to (PV – SP), reversing the sign of the
feedback term. This is for reverse acting controls where the CV must go down
when the PV goes up.
Bit 1: Output Polarity. When this bit is 0, the CV output represents the output of
the PID calculation. When it is set to 1, the CV output represents the negative of
output of the PID calculation. Setting this bit to 1 inverts the Output Polarity so
that CV is the negative of the PID output rather than the normal positive value.
Bit 2: When this bit is 1, the setpoint is removed from derivative calculation. For
details, see the discussion on page 15.
Bit 3: Deadband action. When the Deadband action bit is 0, no deadband action
is chosen. If the error is within the deadband limits, the error is to be zero.
Otherwise the error is not affected by the deadband limits.
If the Deadband action bit is 1, deadband action is chosen. If the error is within
the deadband limits, the error is forced to be zero. If, however, the error is
outside the deadband limits, the error is reduced by the deadband limit (error =
error – deadband limit).
Bit 4: Anti-reset windup action. When this bit is 0, the anti-reset windup action
uses a reset back calculation. When the output is clamped, this replaces the
accumulated Y remainder value with whatever value is necessary to produce the
clamped output exactly.
