Function chart number:  FP3400 
The PID controller has a PID motorized potentiometer which can be separately 
adjusted. The functionality is identical with the motorized potentiometer (refer to 
Section 3.9), whereby the PID parameters are emulated in the range from P2231 – 
r2250 (refer to the comparison 
→ Table 3-18).
