Codesys ON OFF Level Control by Structured Text Programming and Visulization - Part1
In this video you can find a comprehensive Codesys sample project that contains ON/OFF level control. Tank level dynamic is simulated by a function block and whole the programm is written by Structured Text (ST). Finally by designing an interface in Codesys visulization you can control the Auto/Manual mode, Setpoint level, dead zone (Hysteresis), the charging pump and discharge valve.
