mode. Users can adjust conversion characteristic curve by changing OFFSET values (CR#18~CR#21)
and GAIN values (CR#24~CR#27) depend on application.

1. When power is on, POWER LED will be lit and ERROR LED will be lit for 0.5 second.
2. It is normal that POWER LED should be lit and ERROR LED should turn off. When power supply
is lower than 19.5V, ERROR LED will blink continuously till the power voltage is higher than 19.5V.
3. When it connects 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 during controlling via RS-485, A/D LED or D/A LED
should blink.
5. After converting, ERROR LED should blink if input or output exceeds the upper bound or below
the lower bound.

DVP-series PLC uses this command to read CR data of special module.
: When assign the bit operand, K1~K4 are used for 16-bit and K5~K8 are used for
32-bit.
Please refer the footnote below for calculation the special module number.
Read the content of CR#24 of special module#0 save it to D0 of PLC, and read the
content of CR#25 of special module#0 save it to D1 of PLC. 2 data are read in one

B. 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.
