Checklist: Planning Classes

Because a point class is a template for objects that may be created in remote as well as local projects, it is essential that you plan the class to anticipate all possible object requirements.

A brief checklist includes the following setup considerations. Beginning with CIMPLICITY 9.5, Composite Classes are supported.

Determine if the:

	Application in the production facility, if more than one object (process) appears to have similar requirements.
	PLC layout is consistent among the objects (where applicable).
	Data to be collected is identical. Note: The values do not have to be identical.
	Layout of how memory is stored in the devices from which data is collected.
	Calculations needed for the data are identical.
	CIMPLICITY features, e.g. points, scripts, actions and events, required to collect and calculate data.
