Address
For the address, the first 2 bytes are the address and the next byte specifies the bit position
Example: to specify DM100

Structure of Read and Write Data
The format of read data and write data differs depending on whether bits, bits with forced ON/OFF status, words, or words with forced ON/OFF status are specified
== When bits are specified ==
One bit is represented by one byte
Example: representing the 3 bits OFF-ON-OFF
== When bits with forced ON/OFF status are specified ==
One bit is represented by one byte
| |
|
|
|
|
|
Bit 0: 0 = OFF, 1 = ON |
|
Bit 1: 0 = not forced, 1 = forced |
Example: representing forced OFF
Example: representing forced ON
== When words are specified ==
One word is represented by 2 bytes
== When words with forced ON/OFF status are specified ==
One word is represented by 4 bytes
