HONEYWELL FC-TSAI-1620M模擬量模塊,FC-TSAI-1620M使用在哪里
位0：錯誤極性。當(dāng)該位為0時，誤差項(xiàng)為SP-PV。當(dāng)此位為1，誤差項(xiàng)為PV-SP。將該位設(shè)置為1會修改標(biāo)準(zhǔn)PID誤差從正常（SP–PV）到（PV–SP）的術(shù)語，反轉(zhuǎn)反饋項(xiàng)。這適用于CV必須下降的反向作用控制當(dāng)PV上升時。位1：輸出極性。當(dāng)該位為0時，CV輸出表示PID計算。當(dāng)設(shè)置為1時，CV輸出表示PID計算的輸出。將該位設(shè)置為1會反轉(zhuǎn)輸出極性該CV是PID輸出的負(fù)值，而不是正常的正值。
HONEYWELL FC-TSAI-1620M模擬量模塊位2：當(dāng)該位為1時，從導(dǎo)數(shù)計算中刪除設(shè)定點(diǎn)。對于詳情見第15頁的討論。位3：死區(qū)動作。當(dāng)死區(qū)動作位為0時，無死區(qū)動作已選擇。如果誤差在死區(qū)范圍內(nèi)，則誤差為零。否則，誤差不受死區(qū)限制的影響。如果死區(qū)動作位為1，則選擇死區(qū)動作。如果誤差在死區(qū)極限時，誤差被迫為零。然而，如果錯誤是在死區(qū)極限之外，誤差由死區(qū)極限減?。ㄕ`差=錯誤–死區(qū)限制）。位4：防復(fù)位收卷動作。當(dāng)該位為0時，反復(fù)位結(jié)束動作使用重置反向計算。當(dāng)輸出被鉗制時，這將替換累積Y余數(shù)值，具有生成精確鉗位輸出。當(dāng)位為1時，這將用Y項(xiàng)的值替換累積的Y項(xiàng)在計算開始時。這樣，預(yù)鉗位Y值保持的時間盡可能長當(dāng)輸出被鉗位時。位5：啟用導(dǎo)數(shù)濾波。當(dāng)該位設(shè)置為0時，不應(yīng)用濾波導(dǎo)數(shù)項(xiàng)。當(dāng)設(shè)置為1時，應(yīng)用一階濾波器。這將限制導(dǎo)數(shù)項(xiàng)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.
