Accessing Instantiated Instances

In this chapter, you will learn how to access imbedded Instantiated

Instances (assemblies) in the software. The Encoder/Counter Module uses several words to communicate real time input and output data as well as non-real time module information (i.e. description, revision, etc) and configuration. These words have been preprogrammed into

Instantiated Instances.

Click on the module to select the Class

Instance Editor.

Click on Yes when this screen appears.
