794 -This instruction is to complete large time-delay system control operation, and used to control the parameters of the closed-loop control system.
795 -
796 -[[image:1758111592778-873.png]]is the target value of CCPID SHT control (SV).
797 -
798 -[[image:1758111614838-309.png]]is the measured feedback value (PV).
799 -
800 - ​​​​[[image:1758111642557-547.png]]is the start address of the cache where the parameters required by LAGCDL operation and intermediate results are saved,
801 -
802 -occupying a total of 634 variable units of subsequent addresses. The value range is from D0 to D7974 or from R0 to R35000. 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.
803 -
804 -[[image:1758111693192-390.png]] is the storage unit of the LAGCDL 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.

809 -
810 -The parameter description is as follows:
811 -
812 -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..
813 -
814 -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.
815 -
816 -D100 unit is used to store the calculated control output value to control the execution of the action.
817 -
818 -[[image:1758111862269-781.png]] to [[image:1758111862269-781.png]]+15 is the parameter range that can be set (parameters set when LAGCDL is executed). [[image:1758111862269-781.png]]+28 to [[image:1758111862269-781.png]]+631 is the historical data space for LAGCDL control internal use. [[image:1758111862269-781.png]]+4 to [[image:1758111862269-781.png]]+27 is the parameter space used in the self-tuning process. (This space is multiplexed with the parameter space during control)
