SSEMBLY
The following parameters are used in the output assembly of the module.
Parameter
Datatype Description
RoutingInhibit
BOOL
This bit inhibits the module’s routing capabilities.
When set, no DF1 messages are routed. This may be required in
applications running a redundant DF1 network where one of the
PLX51-DF1-ENIs is to run in a hot-standby mode.

UNSCHEDULED MESSAGING
When the PLX51-DF1-ENI is configured in Unscheduled Mode, it processes DF1 message
requests sent from Logix via a message instruction.
To simplify the configuration of the required message, a number of UDTs have been
preconfigured. They are available on the ProSoft Technology PLX51-DF1-ENI website.
Example:
