Titel: Need to select set point of Minimum/Maximum Pressure through MFD.
Beitrag von: hinddhindsa am Juli 17, 2013, 07:52:07 Vormittag

Hi dear EASY friends :D. where the set points value are stored which we enter through MFD-80-B+CP4-800. I designed my program for booster pomp applications.what can be done if i want to give minimum  and maximum pressure limit from HMI,
Minimum pressure set point is 2 bar which is cut in pressure for 3 pumps and maximum cut off pressure will be 4 bar (operator may increase it to 5 or 6 bar also).
please help me.

Dear hinddhindsa.

Without knowing your program I can only make some guesses.

I assume you are using the analogue comparator function block A to start the motor.
Within this function block the input value I1 or I2 and the hysteresis value HY have to be
changeable and not a constant, for example by using a word value MW.
These values MW you can show on your display by using a text function D and mark them as
editable.

I propose to upload your program or at least the important part to give to you more detailed advice.
