Integration function
With this function, the computed value from the linearization table or that of the analog input can
be numerically integrated to create a totalizer for example.
The totalizer is calculated as follows:
The measuring interval is 0.1 s.
In most instances, the integration basis is the same time unit as the time basis of the signal to be
integrated.
Example: analog input l/s
