Integral term

The output Y reflects the integral value of the input X over the time.

Input Ti selects the time constant. A logical 1 at the preset input Pr causes the integrator to assume the preset value PrW.

The trapezoid rule is used to compute the integral. Integration constant K is only computed at program start, or whenever Ti changes:


The integral term realizes the following function:

Step response:


Name I/O Type(s) Function
X I FLOAT Input signal
Ti I FLOAT Time constant in [s]
Pr I BIT Preset
PrW I FLOAT Preset value
Y O FLOAT Output signal


This function block is a basic term to create structures.
