Parameter Description
Requested Packet Interval (RPI) Enter an RPI value or use the default.
Inhibit Module Check the box to prevent communication between the owner-controller and the module. This
option lets the module be maintained without faults being reported to the controller.
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.
For important information on this checkbox, see ‘Configure a Major Fault to Occur’ in the
Logix5000 Controllers Information and Status Programming Manual, publication 1756-PM015 .
Use Unicast Connection over EtherNet/IP Choose between Unicast and Multicast for EtherNet/IP connections. This checkbox is enabled
when the module supports Unicast at the current revision and any part of the module path
crosses EtherNet/IP.
It is checked and dimmed when the module supports only Unicast and any part of the module
path crosses the EtherNet/IP network.
The checkbox is not checked and dimmed if these conditions are true:
• The module’s current revision does not support Unicast. Note that in the case of a module
that is Multicast only, no revision supports Unicast.
• The module is proxied (for example, 1734, 1738 and 1794 modules) and the parent’s
current revision does not support Unicast.
Unicast is not supported with ControlLogix Redundancy, version 19.52.
