控制器输出具有MINSCALE和MAXSCALE参数，允许对输出信号进行缩放默认值为0-100 PRCT以外的工程范围。当控制器输出为设置点到另一个控制器。
当自动调谐设置为“是”时，可使用调谐按钮访问自动调谐功能，并且可以：在回路处于自动或手动状态时启动。当启动时，自动调谐器用开关控制代替PID功能，将A/M模块置于Auto（如果处于Man）状态，并通过六个开-关周期循环控制回路，同时学习其用于为PID控制器提供调整建议的过程动力学。
%DEV参数是在开关周期。该参数可以手动设置，也可以配置为自动。配置“自动”时自动调谐将%DEV设置为%HYS的4倍。这是提供良好自动调谐所需的最小值后果%HYS参数是在中切换输出之前过程必须偏离设定值的量相反的方向。该值必须至少等于或略大于任何工艺噪声带。如果噪音无法确定频带，当%HYS参数已配置为自动。%阶跃参数是阀门在第一个开-关循环中的变化量。在第一个循环之后autotuner将调整步长，以将进程保持在%DEV参数的值内。随后自动调谐练习，该步骤将使用从上一练习计算的值，除非AT RESET参数设置为“是”或控制器已通电。自动调谐建议的动态响应可以是：配置为快速、中等或慢速。
介质设置通常会提供一个没有或很少的响应超调至设定点阶跃响应。
当POST AT参数设置为YES时，控制回路将使用推荐的调整值，除非测试期间出现警告。

The controller output has MINSCALE and MAXSCALE parameters allowing the output signal to be scaled for
engineering ranges other than the default of 0-100 PRCT. This may be necessary when the controller output is the
setpoint to another controller.
The Autotune feature is accessible using the TUNE pushbutton when AUTOTUNE is set to YES and can be
initiated while the loop is in Auto or Manual. The autotuner, when initiated, replaces the PID with an on-off control
function, places the A/M block in Auto (if in Man) and cycles the control loop through six on-off cycles while
learning the process dynamics which it uses to provide tuning recommendations for the PID controller.
The % DEV parameter is the maximum amount in % that the process should deviate from the setpoint during the
on-off cycles. This parameter can be set manually or can be configured as AUTO. When AUTO is configured, the
autotuner will set the % DEV to 4 times the % HYS. This is the minimum value needed to provide good autotuning
results.
The % HYS parameter is the amount that the process must deviate from setpoint before switching the output in the
opposite direction. This value must be at least equal to or slightly greater than any process noise band. If the noise
band cannot be determined, the autotuner will compute it at the start of an autotuning exercise when the % HYS
parameter has been configured as AUTO.
The % STEP parameter is the amount that the valve will change on the first on-off cycle. After the first cycle, the
autotuner will adjust the step to keep the process within the value of the % DEV parameter. On subsequent
autotune exercises, the step will use the value computed from the previous exercise unless the AT RESET parameter
is set to YES or the controller has been power cycled. The dynamic response recommended by the autotuner can be
configured as Fast, Medium, or Slow. The Medium setting will normally provide a response that has no or little
overshoot to a setpoint step response.
When the POST AT parameter is set to YES, the control loop will be returned to Auto using the recommended
tuning values unless a warning occurred during the test.
More details on autotuning can be found in the Operation section. PIDAG is an adaptive gain proportional + integral
controller and is one of five controller types that can be
used on a one per loop basis. It uses external feedback to
provide integral action that allows interaction with other
function blocks or external devices, such as pneumatic
controllers, shutoff switches. PIDAG eliminates windup
that can occur with other controller types. Derivative
action is provided when the parameter TD is non-zero. The
controller includes an autotune feature that can be initiated
from the operator faceplate using the quick TUNE feature.
