Explanation:

Read the model type of extension module K0 (should be H0402 for DVP04PT-H model type).

The average values of CH1~CH4 saved in D10~D13 are written into CR#2~CR#5.

For DVP04PT-H model. The read average temperature (°C) of CH1~CH4 (4 data) from CR#6~CR#9 and saved to D20~D23.

The read average temperature (°F) of CH1~CH4 (4 data) from CR#12~CR#15 and saved into D24~D27.

The read present temperature (°C) of CH1~CH4 (4 data) from CR#18~CR#21 and saved into D30~D33.

The read present temperature (°F) of CH1~CH4 (4 data) from CR#24~CR#27 and saved into D34~D37.

instruction (TOP, DTOP)

Command

: the module number you are probing.

: the number of Controlled

Explanation

Registers to be written to.

: the data to write.

: the number of CR to be

written to in one time.

DVP-series PLC uses this instruction to write data to Controlled Registers of

special modules.

: When assign the bit operand, K1~K4 are used for 16-bit and K5~K8 are

used for 32-bit.

Program

Using the 32-bit instruction DTO. The program will write D11 and D10 into CR#3

Example

and CR#2 of special module#0. DTO only allows one group of data to be written at

a time (n=1).

The instruction is executed when X0=ON. Nothing will occur and the stored data will have no change when X0=OFF.

DTO K0

The rules for adding multiple special modules to a Main Processing Unit:

Footnote

m1: The maximum number of special modules attached to an MPU is 8. The module closest to the MPU is 0 and the module furthest from the MPU is 7. m2: The number of Controlled Registers (CR) built in is 49. (#0~#48).

FROM/TO instruction read/write one CR at a time, while DFROM/DTO instruction read/write two CR at a time. Example below:

DVP-series PLC uses this instruction to read CR data of each special module.

: When assigning bit operand, K1~K4 are used for 16-bit and K5~K8 are used for 32-bit.

Please refer the following footnote for calculating of special module number.

Program	Read the content of CR#24 and CR#25 of module#0 and save it into D0 and D1
Example	when n=2.

Instruction will be executed when X0=ON. However, nothing will occur and the stored data has no change when X0=OFF.

16-bit command when n=6

32-bit command when n=3

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 FROM/TO instruction is completed. 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.

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.
