Hello there,
I just graudated from university and i am pretty new at PLC . where i work , they asked me to build a system . I want to share this system with you and the steps which i consider (S7 1200). I will be grateful for any help or source.
System : Any liquid flows through an u-shaped pipe with a pump.
Inputs : speed of pump and pressure (bar) Outputs : power of pump and flow
Steps: Read from pressure transmitter ( scaling-unscaling)
Enter set values on HMI ( rpm , bar )
Compare values ? *** i dont know how compare
PID Compact
Proportional control ( move command )
Show outputs on HMI (flowmeter and current )
Maybe i can use PC instead of HMI for C# HMI application .( S7.Net library)
Have a nice day...
