	52	+What is stored in D9 is the target value of PID adjustment, and D10 is the closed-loop feedback value. Note that D9 and D10 must be of the same dimension, such as both 0.01MPa units, or 1℃ units, etc.;
	53	+
	54	+A total of 26 units of D200 to D225 are used to store the set value and process value of PID operation. These values must be set item by item before the first PID calculation;
	55	+
	56	+The D130 unit is used to store the calculated control output value to control the execution of the action.

	92	+● When multiple instructions are used, the device number of (d) cannot be repeated.
	93	+
	94	+● During the execution of auto-tuning, the (s3) parameter space cannot be modified.
	95	+
	96	+● The instruction occupies 26 point devices from the device specified in (s3).
	97	+
	98	+● PID instruction can be used multiple times in the program and can be executed at the same time, but the variable area used in each PID instruction should not overlap; it can also be used in step instructions, jump instructions, timing interrupts, and subroutines, in this case When executing the PID instruction, the (s3)+9 cache unit must be cleared in advance.
	99	+
	100	+● The maximum error of the sampling time Ts is -(1 operation cycle +1ms) +(1 operation cycle). If the sampling time Ts ≤ 1 operation cycle of the programmable controller, the following PID operation error (4D86H) will occur, and the PID operation will be executed with TS = operation cycle. In this case, it is recommended to use constant scan mode or use PID instruction in timer interrupt.

	325	+
	326	+**Background:**
	327	+
	328	+PID (proportion, integral, derivative) controller has been the earliest practical controller for nearly a hundred years, and it is still the most widely used industrial controller. The PID controller is simple and easy to understand, and does not require precise system models and other prerequisites in use, making it the most widely used controller.
	329	+
	330	+**Purpose:**
	331	+
	332	+You might not be familiar with the parameter settings in the new series of CCPID for the first time, this manual could let you quickly understand the meaning of each parameter in the CCPID and the influence on the control effect, so that you can quickly learn the CCPID.

The function and parameter description of each unit are described in this section;

	363	+
	364	+The parameter description is as follows:
	365	+
	366	+In D9, the target value of PID adjustment is stored, and D10 is the closed-loop feedback value. Note that D9 and D10 must be of the same dimension, such as both 0.01MPa units, or 1℃ units, etc.;
	367	+
	368	+A total of 52 units of D200 to D224 are used to store the set value and process value of PID operation. These values must be set item by item before the first PID calculation;
	369	+
	370	+D130 unit is used to store the calculated control output value to control the execution of the action.
	371	+
	372	+The functions and setting methods of the parameter values of each unit used by [[image:file:///C:\Users\Administrator\AppData\Local\Temp\ksohtml11524\wps176.png]]are described in the following table:

	575	+When the control system is a single temperature control system or a system where environmental interference does not cause large fluctuations. Generally the automatic tuning without transition zone is selected, so that the self-tuning process can be completed more quickly than the method with transition zone.

	593	+Figure 4 Process curve without different working interval parameters (heating process diagram)
	594	+
	595	+It can be seen from the partially enlarged graph that the parameters of the working interval have a certain influence on the overshoot and the stable time. In the case of allowing overshoot, setting the working interval parameters can make the overshoot smaller. This is because the deviation E of PID starting to work is relatively small, and the integration accumulation will not quickly saturate.

	597	+* **Result of filter coefficient setting**

	601	+Figure 5 Process curve under different filtering parameters
	602	+
	603	+The figure above is the experimental result under the small overshoot coefficient, the sample time is 1s. The coefficients of the first-order inertial filtering are (20, 50, 70, 80, 90). After adding the inertia coefficient, the stability time of system control is greatly accelerated, and it is increased by about 6 minutes for the boiling water experiment. The overshoot is about 1.2°C to 1.7°C.
	604	+
	605	+Therefore, the introduction of first-order inertial filtering could greatly improve the PID environment where the temperature fluctuates to a certain extent and increase stabilization time.
	606	+
	607	+**✎Note:** This parameter of filter coefficient is helpful for systems with not very large hysteresis or the control effect of the phenomenon that the control amount fluctuates back and forth has been greatly improved.

	627	+When selecting working mode 2, there are three corresponding adjustable parameters: ukp[S3+10], uki[S3+11], ukd[S3+12]. Usually, the default parameters can be used for ukp and uki. Adjust the value of ukd could achieve the control effect.
	628	+
	629	+Ukp is adjusted when the value of Kp reaches the maximum value, and the default value is usually 100.
	630	+
	631	+Uki is adjusted when periodic oscillations occur. Gradually increase the value of uki to track the control effect.

	828	+
	829	+The parameter description is as follows:
	830	+
	831	+The target value of LAGCDL adjustment is stored in D1, and D0 is the closed-loop feedback value. Note that D0 and D9 must be of the same dimension, such as both 0.01MPa units, or 1℃ units, etc..
	832	+
	833	+A total of 634 units of D1000 to D1633 are used to store the set value and process value of LAGCDL operation. These values must be set item by item before the first LAGCDL calculation.
	834	+
	835	+D100 unit is used to store the calculated control output value to control the execution of the action.
