HONEYWELL FC-TSAI-1620M模拟量模块,FC-TSAI-1620M使用在哪里
位0：错误极性。当该位为0时，误差项为SP-PV。当此位为1，误差项为PV-SP。将该位设置为1会修改标准PID误差从正常（SP–PV）到（PV–SP）的术语，反转反馈项。这适用于CV必须下降的反向作用控制当PV上升时。位1：输出极性。当该位为0时，CV输出表示PID计算。当设置为1时，CV输出表示PID计算的输出。将该位设置为1会反转输出极性该CV是PID输出的负值，而不是正常的正值。
HONEYWELL FC-TSAI-1620M模拟量模块位2：当该位为1时，从导数计算中删除设定点。对于详情见第15页的讨论。位3：死区动作。当死区动作位为0时，无死区动作已选择。如果误差在死区范围内，则误差为零。否则，误差不受死区限制的影响。如果死区动作位为1，则选择死区动作。如果误差在死区极限时，误差被迫为零。然而，如果错误是在死区极限之外，误差由死区极限减小（误差=错误–死区限制）。位4：防复位收卷动作。当该位为0时，反复位结束动作使用重置反向计算。当输出被钳制时，这将替换累积Y余数值，具有生成精确钳位输出。当位为1时，这将用Y项的值替换累积的Y项在计算开始时。这样，预钳位Y值保持的时间尽可能长当输出被钳位时。位5：启用导数滤波。当该位设置为0时，不应用滤波导数项。当设置为1时，应用一阶滤波器。这将限制导数项上的高频过程干扰。可配置为128字增量，从128到带DOS编程器的16384个字，来自128Windows程序员版本为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.
