| READ, | 1, | RS, | 1001, | 0, | 20, |
| READ, | 2, | RS, | 1001, | 20, | 20, |
1) Station : Station number which set at controller.
Station - 0 ~ 255 (Low byte), sub Station – High byte.
2) Data Type : Data type to read. Fixed to RS.
3) Read Start Address : Memory start address to read. Refer to communication parameter table manual of SDC/DMC controller about memory address.
4) Save Start Address for Communication Server : Saving start address of Communication Server.
5) Read Size : read size.

Write to direct address of controller, regardless of SCAN File.
Digital Write
You can set or control SDC/DMC controller by using the digital write command.
Digital write setting parameters are as follows :
1) PORT : Connected Port no.(0 ~ 255)
2) Station : Station number which set at controller.
Station - 0 ~ 255 (Low byte), sub Station – High byte.
3) ADDRESS : Memory address of communication parameter table. (Decimal)
4) Extra1 : If Extra2 is '1', it is bit position. (0 ~ 15).
5) Extra2 : 1 : ON/OFF of bit unit.
Etc : Output the value as 0 or 1.
Ex) Port:0, Station:1, Address:1008, Extra1:3, Extra2:1
After writing as digital, you can change(ON/OFF) the 4th bit value of SP ch1 of SDC/DMC controller.
Analog Write
You can set or control SDC/DMC controller by using the analog write command.
Analog write setting parameters are as follows :
1) PORT : Connected Port no.(0 ~ 255)
2) Station : Station number which set at controller.
Station - 0 ~ 255 (Low byte), sub Station – High byte.
3) ADDRESS : Memory address of communication parameter table. (Decimal)
4) Extra1 : Don't care.
5) Extra2 : Don't care.
Ex) Port:0, Station:1, Address:1009
After writing as analog, you can set SP ch2 value of SDC/DMC controller.
