Communication protocol 133
Class objects
The following table lists the data types used in the class object
descriptions of this manual. The table also includes the
corresponding data type names of the Common Industrial Protocol
(CIP) Specification.
Note: The adapter module is designed to provide DeviceNet
communications for a variety of drives with different capabilities.
Default, minimum and maximum values for attributes necessarily
vary based upon the capabilities of the drive to which the module is
attached and are not documented herein. Default, minimum and
maximum values for attributes may be found in the:
• User’s manual for the drive
• Electronic Data Sheet Files (EDS) for the drive.
Note that the units of the attributes may differ from those of the
parameters documented elsewhere and those differences must be
considered when interfacing to the drive via the module.
