Chapter 5 Function code table
When PID reference source is digital setting, PID digital setting 0~3 depends on DI terminal function 43 (preset PID
terminal I ) and 44 ( preset PID terminal 2):

For example: When AI1 is used as PID feedback, if the full range corresponds to 16.0Kg pressure and require PID
control to be 8.0Kg; then set P40.05 PID feedback range to 16.00, PID digital reference terminal select to P40.06,
Set P40.06 (PID preset setting 0) to be 8.00
