Prozessleittechnik LFIC 2000

"The Unit" to learn about two typical controlled members level & flow and to study the PID algorithms using original industrial components.

Prozessleittechnik LFIC 2000
 
Control modes:
  • 2-Position control switching pump on/off
  • 3-Position step control with slow motor valve
  • Continous control with speed controlled pump
  • Feed foreward
  • Cascade
 
Controlled members:
  • Waterlevel measured by bottom pressure
  • Waterflow measured by magnetic flow-meter
 

Controller:

Industrial controller or PLC
PC and TeLC software controller, special features when using PC and TeLC software controller: Time plots of I/O and of PID - actions of output value (Windows-software).
