Configure ControlLogix Digital I/O Modules Chapter 7
Connection Properties Connection properties define controller-to-module behavior. When defining
connection properties, you can do the following:
• Select a requested packet interval (RPI) to set a defined, maximum period
of time when data is transferred to the owner-controller
• Choose to inhibit the module
• Configure the controller so that a loss of connection to this module causes
a major fault
• View information about the condition of the connection between the
module and the controller
Follow these steps to configure connection properties.
1. On the Module Properties dialog box, click the Connection tab.
2. Complete the fields as described below and click OK.
Field Description
Requested Packet Interval (RPI) Enter an RPI value or use the default.
See
RPI in Chapter 2 for more information.
Inhibit module Check the box to prevent communication between the owner-controller and the
module. This option allows for maintenance of the module without faults being
reported to the controller.
See
Module Inhibiting in Chapter 3 for more information.
Major fault On Controller If
Connection Fails While in Run Mode Check the box to create a major fault if there is a connection failure with the
module while in Run mode.
