Configuring the I/O Chapter 4
For the example in this manual, all 16 Host [DL From Net xx] and all 16
Host [DL To Net xx] are used, resulting in an Input Size of “19” and an
Output Size of “18.”
7. After setting the information in the drive’s New Module dialog box, click
OK.
The Module Properties dialog box appears.
8. Click the Connection tab.
9. In the “Requested Packet Interval (RPI)” box, set the value to 2.0
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.
Unicast support has been added to RSLogix 5000 software, version 18.00
(or later). Unicast is recommended whenever possible. For the benefits of
unicast operation, see
Preparing for an Installation on page 17 .
10. Click OK.
The new node (“My_PowerFlex_753_Drive” in this example) now
appears under the bridge (“My_EtherNet_IP_DLR_Bridge” in this
example) in the I/O Configuration folder. If you double-click the Input
and Output Controller Tags (
Figure 13 and Figure 14 ), you will see that
module-defined data types and tags have been automatically created. After
you save and download the configuration, these tags allow you to access
the Input and Output data of the drive via the controller’s ladder logic.
