  • 5. Programming Ladder Logic Routine

    Let’s begin to program the ladder logic routine.
    We will add two new rungs to our ladder routine.
    We use a greater than or equal element that compares the tank level tag, with the pump start setpoint tag, and latches the SoftWaterTank.PumpStarter and SoftWaterTank.WaterValve coils.

    These coils w...

  • 6. Programming Structured Text Routine

    Let’s startup Studio 5000, and select the program RealPars_IEC61131, previously created in the first section.
    After the Studio 5000 program starts up, the “Logic Designer GUI” appears. In the “Controller Organizer Area” - “Tasks” folder - “MainProgram” folder, we can see the three different progr...
