Since only one setpoint source can be active at a time, the following priorities apply:
Flexible I/O configuration or keypad control active
0x2631:037 (P400.37)
Prio 1: Functions for setpoint change-over
The priority of the functions results from the assigned triggers (in the
order of the selection list):
1. Constant TRUE [1]
2. Digital input 1 [11]
3. Digital input 2 [12]
4. Digital input 3 [13]
5. ...
Prio 2: Set standard setpoint source
0x2860:001 (P201.01): Frequency control: Default setpoint source
•
0x2860:002 (P201.02): PID control: Default setpoint source
