Integration function
With this function, the computed value from the linearization table or the current flow value for
channel calculation, 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  integration basis s
