This function block will approximate the integral of the function 
over the time interval between the first function call 
and the actual time 
:
The size of the time intervals 
are integers and measured in micro seconds. The approximation is carried out by use of the explicit (lrInputvariable 
) resp. implicit (lrInputvariable 
) Euler method:
lrInputVariable.
(equals time passed since last call to function)
