This is an OPEN-TYPE built-in DVP04AD-H, and the DVP04AD-H is certified to meet the safety
requirements of IEC 61131-2 (UL 508) when installed in the enclosure to prevent high
temperature, high humidity, exceessive vibration, corrosive gases, liquids, airbome dust or
metallic particles. Also, it is equipped with protective methods such as some special tool or key to
open the enclosure, in order to prevent the hazard to users and the damage to the DVP04AD-H.

ꢀ 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.

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.

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.

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.
b. 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.

DVP-series PLC uses this instruction to read CR data of special module.
: When assigning bit operand, K1~K4 are used for 16-bit and K5~K8 are used
for 32-bit.

Please refer the footnote below for the calculation of special module number.
To read the content of CR#24 of special module#0 to D0 of PLC and to read the
content of CR#25 of special module#0 to D1 of PLC. It can read 2 data in one time
