PART 1 AD268
3. Input Type Setting
3.2 Parameter setting by software
The input range of the AD268 is specified by writing the following parameter data into the
AD268's buffer memory. To access the buffer memory, T2 user program (READ and WRITE
instructions) is required.
When the parameter is set to the AD268, it is saved in the AD268's built-in EEPROM.
Therefore, once the input type parameter is set, there is no need to execute the input type
setting operation.
