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 the Port Configuration tab.
11. In the Port Configuration tab dialog box, edit the following information.
Box Setting
IP Address The IP address of the option module that was already set in the General tab. This field is
not configurable (grayed out).
Subnet Mask The Subnet Mask configuration setting of the network. This setting must match the
setting of other devices on the network (for example, 255.255.255.0).
Gateway Address The Gateway Address configuration setting of the network. This setting must match the
setting of other devices on the network (for example, 10.91.100.1).
