Delta DVP-ES2

4 Temperature Measurement Module DVP 04PT-E2
4.6.3 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 DVP04PT-E2, the configuration of special registers is as below:

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 4.8 Applications in this manual) or 2. FROM/TO instructions
(CR#8~CR#11) to set the average times as K1

4.7 Temperature Conversion in D V P 0 4 P T-E2
You can adjust the conversion curves according to the actual needs by changing the Offset value (CR#28 ~ CR#31).
Definition of Offset in DVP04PT-E2:
Deviation digital value from the target temperature/voltage
