Appendix V PID control loop application examples
As shown in the figure, a 2-channel PID single-loop control system is
composed of this series of instruments to achieve a simple temperature
control, the measurement signal is the temperature of the tank, the output
signal to the heating wire (assuming that the heating wire can receive a
continuous signal).
Configuration process.
System configuration: PID rectification selection allowed (for adjusting
PID screen parameters).
Input configuration: temperature channel CH01, parameters
user-defined.
Output configuration: output channel CH02, the signal source is set to
PID01, and the rest parameters are user-defined.
Control configuration: control channel PID01, loop state is selected as
enabled, set value SV is selected as internal given, sampling value PV is
selected as CH01, and the rest parameters are user-defined.
Adjustment process (in PID screen).
