INTRODUCTION
Model Explanation and Peripherals
Thank you for choosing DELTA's PLC DVP Series. The analog input module receives external 4-point analog signal input (voltage or current) and converts it into 14 bits digital signal. The analog input module of DVP04AD-H series can read/write the data of analog input module by using instructions FROM / TO via DVP-PLC EH Series MPU program. There are 49 CR (Control Register, each register has 16-bit) in each module. Software version of DVP04AD-H analog input module can be updated via RS-485 communication. Users can select input from voltage or current via wiring. Voltage input range is 10V DC (resolution is 1.25 mV). Current input range is 20 mA (resolution is 5 A). Nameplate Explanation

Explanation: 1. CR#0: The content of CR#0 is model type, user can read the data from program to know if there is extension module. 2. CR#1: CR#1 is used to set 4 internal channels working mode of analog input module. Every channel has four modes to set and can be set individually. For example: if setting CH1 to mode 0 (b2~b0=000), CH2 to mode 1(b5~b3=001), CH3: mode2 (b8~b6=010), CH4: mode 3(b11~b9=011). It needs to set CR#1 to H0688 and the upper bit (b12~b15) will reserved. The factory setting of CR#1 is H0000. 3. CR#2 ~ CR#5: it is used to set average times of CH1~CH4. Setting range is K1~K4096 and factory setting is K10. 4. CR#6 to CR#9 are the average value that calculates according to the value that is set in CR#2~CR#5 (average time of CH1~CH4 input signal). For example, if CR#2 (the average times of CH1) is 10, it will calculate the average of CH1 input signal every 10 times. 5. CR#10, CR#11, CR#16, CR#17, CR#22, CR#23, CR#28, CR#29 reserved. 6. CR#12 ~ CR#15: display present value of CH1~CH4 input signal. 7. CR #18~ CR #21: the content is the value of adjusting OFFSET value of CH1~CH4 if analog input voltage or current is 0 after it transfers from analog to digital. Voltage setting range: -5V~+5V(-4000LSB~+4000LSB). Current setting range: -20mA~+20mA (-4000LSB~+4000LSB). 8. CR #24~ CR #27: means analog input voltage or current when conversion value from analog signal to digital is 4000. Voltage setting range: -4V~+20V(-3200LSB~+16000LSB). Current setting range: -16mA~+52mA(-3200LSB ~+10400LSB). But please be noticed GAIN VALUE - OFFSET VALUE = +800LSB~+12000LSB (voltage) or +800LSB~+6400LSB (current). When this value under this range, the resolution of the input signal will be thin and the variation of value will be larger. When this value exceeds this range, the resolution of input signal will be thick and the variation of value will be smaller. 9. CR#30 is the fault code. Please refer to the chart below.

Command Explanation
In ES series models, flag M1083 is not provided. When FROM/TO instruction is executed, all interrupts (including external or internal interrupt subroutines) will be disabled. All interrupts will be executed after completing FROM/TO instruction. Besides, FROM/TO instruction also can be executed in the interrupt subroutine. The function of the flag M1083 (FROM/TO mode exchange) provided in EP/EH series models: a. When M1083=Off, all interrupts (including external or internal interrupt subroutines) will be disabled when FROM/TO instruction is executed. The Interrupts will resumed after FROM/TO instruction complete. Please be advised FROM/TO instruction can be executed in the interrupt subroutine. When M1083=On, if an interrupt enable occurs while FROM/TO instruction are executing, the interrupt FROM/TO instruction will be blocked till the requested interrupt finish. Unlike M1080 off situation, FROM/TO instruction cannot be executed in the interrupt subroutine.
