658 +[[image:1758113227549-844.png]] is the start address of the cache where the parameters required by CCPID_SHT operation and intermediate results are saved,
659 +
660 +occupying a total of 36 variable units of subsequent addresses. The value range is from D0 to D7946 or from R0 to R29964. It is better to specify power failure retention, and the setting value remains after power supply is off. Otherwise, the cache needs to be assigned value before starting the calculation for the first time. The function and parameter description of each unit are described in this section.
661 +
662 +[[image:1758113243743-809.png]] is the storage unit of the CCPID_SHT calculation result. Please specify it as a non-battery retentive area, otherwise it needs to be initialized and cleared before the first start of calculation.

667 +
668 +
669 +The parameter description is as follows:
670 +
671 +The target value of CCPID_SHT 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..
672 +
673 +A total of 36 units of D1000 to D1035 are used to store the set value and process value of CCPID_SHT operation. These values must be set item by item before the first CCPID_SHT calculation.
674 +
675 +D100 unit is used to store the calculated control output value to control the execution of the action.
676 +
677 +[[image:1758113227549-844.png]]The functions and setting methods of the parameter values of each unit at the beginning are described in the table below:
