When a 32-bit parameter is selected for Input Data or Output Data for a
drive with 16-bit Datalinks, two contiguous Datalinks (for example, x1
and x2, where x = A, B, C or D) are automatically assigned as a pair to
represent that parameter. See Datalink examples in the screen shown on
the previous page. For more information on Datalinks, see
.
On the Module Definition screen, notice that the automatically-assigned
controller tags DriveStatus, OutputFreq, DriveLogicRslt, and
CommandedFreq are always used.
When a Datalink is enabled, the following 20-COMM-E adapter I/O
parameters are automatically set:
– Parameter 23 - [DPI I/O Cfg] turns on the enabled Datalink bit so
the 20-COMM-E adapter will communicate that Datalink’s
information with the drive.
– Parameter 35 - [M-S Input] turns on the enabled Datalink bit so the
20-COMM-E adapter will input that Datalink’s information from the
controller.
– Parameter 36 - [M-S Output] turns on the enabled Datalink bit so
the 20-COMM-E adapter will output that Datalink’s information to
the controller.
7. Click OK on the Module Definition screen to save the drive and adapter
configuration and close the screen.
The drive’s New Module screen reappears.
Drive
Rating
The voltage and current rating of the drive. If the drive rating is not listed, the
drive database is not installed on your computer. To get the correct drive rating,
use the
Create Database, Web Update, or Match Drive button described
above.
Connection
Parameters via Datalinks. When selecting ‘Parameters via Datalinks’ (default),
the controller tags for the Datalinks use the drive parameter names to which
they are assigned. When selecting ‘Datalinks’, the controller tags for the
Datalinks have non-descriptive UserDefinedData[n] names like those used in
RSLogix 5000 software, version 15.00.
Data
Format
Parameters. When the Connection field is set to ‘Parameters via Datalinks’,
‘Parameters’ is automatically selected. When the Connection field is set to
‘Datalinks’, you must select the number of Datalinks required for your application
in the ‘Data Format’ field.

In the Input Data column, assigns selected drive parameters to be READ by the
controller. In the Output Data column, assigns selected drive parameters to be
WRITTEN by the controller.

When this box is checked, sorts the Input Data and Output Data assigned
parameters by name and then by number, and enables parameter search by
name. When unchecked, sorts the assigned parameters by parameter number
and then by name, and enables parameter search by number.
