Understanding the
Interface to the Drive The DriveLogix controller supports a direct connection to the drive consisting
of 16 inputs and 16 outputs. The tag names and data types associated with the
inputs and outputs are determined by the communication format selection.
Currently, the following three communications formats are available:
• Velocity Control – for typical speed regulated applications
• Position Control – for typical positioning applications
• User-Defined Control – for general use as required.
• Motion Control - for use with Logix motion commands
• Custom User-Defined Control - for general use as required.
Each communication format contains a number of pre-defined tags and
user-defined tags.
The pre-defined tag names and data types correspond to the associated
parameters within the drive necessary to support the selected communications
format. Links must be established in the drive to support the pre-defined tags
and are configured using DriveExecutive
 software. Linking is a mechanism
within the drive that configures data flow within the drive. The links within the
drive to support the pre-defined tags are protected and must be present. If the
associated links are not present, or are deleted, the communication connection
between the controller and drive will be broken.
The user-defined tags are made up of a fixed number of REAL (floating point)
and DINT (double integer) data types. No links are required within the drive
to support these tags. Therefore, links may be created and deleted as required
with no affect on the communication connection between the controller and
the drive. The user-defined tags may be used to address application specific
data needs not covered by the pre-defined tags.
