average of the last 10 readings on CH1.
5. CR#12 to CR#15: The average temperature (
°F). Temperature is calculated by averaging multiple
pieces temperature readings. Example: If CR#2 is 10, the temperature in CR#12 will be the
average of the last 10 readings on CH1.

Initial PLC Start-up
LED display:
1. Upon power-up, the ERROR LED will light for 0.5 seconds the POWER LED will light
continuously.
2. No errors: POWER LED on and ERROR LED off.
Low Voltage error (lower than 19.5V), ERROR LED will blink continuously till the power
supply goes above 19.5V.
3. DVP04-PT connected to PLC MPU in series = RUN LED on MPU will be lit and A/D LED or
D/A LED should blink.
4. After receiving the first RS-485 command, the A/D LED or D/A LED will blink.
5. If the input or output exceeds the upper or lower bounds, the ERROR LED will blink.

For DVP04PT-S model. Read the average temperature (
°C) of CH1~CH4 (4 data) from
CR#6~CR#9 and save it to D20~D23.
Read the average temperature
(°F) of CH1~CH4 from CR#12~CR#15 and save it to D24~D27.
Read the present temperature (
°C) of CH1~CH4 from CR#18~CR#21 and save it to D30~D33.
Read the present temperature
(°F) of CH1~CH4 from CR#24~CR#27 and save it to D34~D37.

below for detail.
Command
Explanation
: the module number you are probing. : the number of Controlled Registers
to be read.
: the data register location for storing data. : the number of CRs
to read at one time.
DVP-series PLC uses this command 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 footnote below for the calculation of special module number.
Program
Example
Read the content of CR#24 and CR#25 of module#0 and save it to D0 and D1 when
n=2.
Command will be executed when X0=ON. Nothing happen if X0=OFF, the stored
data will have no change.

Flag: When M1083 On, it allows
to enable interrupt during
FROM/TO. Refer to the below for
detail.
Command
Explanation
: the module number you are probing. : the number of Controlled
Registers that will be written to.
: the data to write. : the number of CR to
write to one time.
DVP-series PLC uses this command to write data to Controlled Registers of special
modules.
: When assign bit operand, K1~K4 are used for 16-bit and K5~K8 are used
for 32-bit.
Program
Example
Using 32-bit command DTO. The program will write D11 and D10 to CR#3 and
CR#2 of special module#0. DTO allows only one group data to be written at one
time when n=1.
Command is executed when X0=ON. Nothing happen if X0=OFF, the stored data
will have no change.

Footnote
The rules for adding multiple special modules to a Main Processing Unit:
m1: The maximum number of special modules attached to an MPU is 8. The
module closest to the MPU is 0 and the furthest module to the MPU is 7.
m2: The number of Controlled Registers (CR) built in is 49. (#0~#48).
FROM/TO command read/write one CR at a time, while DFROM/DTO
command read/write two CR at a time. Example below:

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