How you configure a class begins with how the class will be applied. Determining if configuration for more than one process can be streamlined by using a class template enables you to decide if using a class as a template is an effective configuration decision.
Points to consider include if:
There are several objects (processes) that appear to have similar requirements.
The type of data to be collected is identical. The values do not have to be identical.
The type of calculations is identical.
(Where applicable) If the PLC layout is consistent among the objects.
Several plants in a company use tanks that collect similar data.
