The variations in Control Mode and Control Method result in a set of basic
Device Function Codes that help organize the many attributes of the Motion
Control Axis. Device Function Codes are designated by using a letter identifier or
a combination that you can use to determine what attributes are required for
implementation of a given CIP Motion device. The list of Device Function Codes
is as follows:
