Configuring the I/O Chapter 4
b. From the Port field pull-down menu, choose the port of the device to
which this Datalink will be assigned (for this example, Port 0, the
PowerFlex 755 drive).
c. From the Parameter field pull-down menu for the selected device,
choose the parameter to which this Datalink will point (for this
example, drive parameter 370 - [Stop Mode A]).
d. Click OK to complete configuration of the Datalink.
The name of the parameter that this Datalink points to is now shown in
the row on the Module Definition dialog box.
e. Repeat Steps 6a through 6d for each Datalink being configured.
7. Click OK on the Module Definition dialog box to save the drive and
option module configuration, and close the dialog box.
The drive’s New Module dialog box reappears.
8. Click the Connection tab.
9. In the ‘Requested Packet Interval (RPI)’ box, set the value to 5.0
milliseconds or greater (default is 20.0 milliseconds).
This value determines the maximum interval that a controller should use
to move data to and from the option module. To conserve bandwidth, use
higher values for communicating with low priority devices.
The ‘Inhibit Module’ box, when checked, inhibits the module from
communicating with the RSLogix 5000 project. When the ‘Major Fault
On’ box is checked, a major controller fault will occur when the module’s
connection fails while the controller is in the Run Mode. For this example,
leave the ‘Inhibit Module’ and ‘Major Fault On’ boxes unchecked.
10. Click OK on the New Module dialog box.
The new node (‘My_PowerFlex_755_Drive’ in this example) now appears
under the bridge (‘My_ControlNet_Bridge’ in this example) in the I/O
Configuration folder. If you double-click the Controller Tags, you will see
that module-defined data types and tags have been automatically created
(
Figure 6 and Figure 7 ). Note that all tag names are defined and Datalinks
include the assigned drive parameter name. After you save and download
