Control funcons
The exible I/O conguraon serves to congure dierent control funcons for the process
controller:
•
0x2631:045 (P400.45): Deacvate PID controller
•
0x2631:046 (P400.46): Set process controller output to 0
•
0x2631:047 (P400.47): Inhibit process controller I-component
•
0x2631:048 (P400.48): Acvate PID inuence ramp
For details see chapter "Process controller funcon selecon". ^ 585
Status signals for congurable outputs
The process controller provides dierent internal status signals. These status signals can be
assigned to the relay, the digital outputs or the NetWordOUT1 status word.
For details see chapter "Conguraon of digital outputs". ^ 603
