Parameters Description
Requested Packet Interval The Requested Packet Interval (RPI) specifies the rate at which the module and the ControlLogix
controller exchange data to and from each other. The allowable RPI’s range is from 60…750 ms,
with a default of 60 ms. When the specified time frame elapses, the module and the ControlLogix
controller produce data for each other.
Inhibit Module Check or clear this box to inhibit or uninhibit your connection to the module. Inhibiting the module
causes the connection to the module to be closed.
When you check this box and go online, the icon representing this module in the controller organizer
displays the Inhibited icon.
Major Fault On Controller If Connection Fails While in Run Mode Check this box to configure the controller so that failure of the connection to this module causes a
major fault on the controller if the connection for the module fails.
Use Unicast Connection over EtherNet/IP Choose between Unicast and Multicast for EtherNet/IP connections.
Use only Multicast in redundancy applications or else the connection drops upon switchover. Make
sure the box is unchecked.
