As just beginner I 'd like to get program example how to manage pump control which uses my fine working (4-20 mA) linearization block. Assuming next step would be compare it to certain values which should be able to change by up/down arrows..
So I could keep vessel level between adjustable minimum / maximum by the pump. Any links to examples?
I recommend you start from Examples of Visilogic.
Shortest way to open Examples is to go to "Help->Examples...) menu option.
Then go to "Version 900->Project examples" directory.
"V280_ON_off_control_with_hysteresis_and_high_and_low_alarms.vlp" project was written for heating control with hysteresis.
This project will be adopted to control Pump.
"V120_Variable_enter_control.vlp" project is a simple example fo Variable entry control.
I hope this answers your questions.
