Explanation on Special Registers D9900~D9999

When ES2 MPU is connected with modules, registers D9900~D9999 will be reserved for storing values from
modules. You can apply MOV instruction to operate values in D9900~D9999.
When ES2 MPU is connected with DVP04AD-E2, the configuration of special registers is as below:
Module#0 Module #1 Module #2 Module #3 Module #4 Module #5 Module #6 Module #7
D1320 D1321
D9900 D9910
D9901 D9911
D9902 D9912
D9903 D9913
1. D9900~D9999 are average input values of CH1 ~ CH4 and the average times is K1~K100. When the average
times is set to K1, the values displayed in D9900~D9999 are current values. You can use: 1. ES_AIO
Configuration Function of WPLSoft (refer to 1.8 Applications in this manual) or 2. FROM/TO instructions
(CR#8~CR#11) to set the average times as K1.

1.7 A/D Conversion Curve

You can adjust the conversion curves according to the actual needs by changing the Offset value (CR#28 ~ CR#31)
and Gain value (CR#34 ~ CR#37).
Gain (in DVP04AD-E2): The corresponding voltage/current input value when the digital output value = 16,000.
Offset (in DVP04AD-E2): The corresponding voltage/current input value when the digital output value = 0.
