PART 3 TC218 3. Input Type Setting
3.2 Parameter setting by software
The input type of the TC218 is specified by writing the following parameter data into the
TC218's buffer memory. To access the buffer memory, T2 user program (READ and WRITE
instructions) is required.
When the parameter is set to the TC218, it is saved in the TC218's built-in EEPROM.
Therefore, once the input type parameter is set, there is no need to execute the input type
setting operation.
