Attribute Description
TimeoutMultiplier Specify the timeout multiplier (default = 2) for a safety controller system. This value determines the RPIs of time to wait
for a packet before declaring a time out. This translates into the number of messages that may be lost before declaring a
connection error. A Timeout Multiplier of 1 indicates that no messages may be lost, which means there must be a packet
every RPI interval. A Timeout Multiplier of 2 indicates that 1 message may be lost, which means as long as a packet is
seen in 2 times the RPI, no time-out will occur. Type a number from 1...4, inclusive.
This attribute applies only to safety consumed tags.
For L5X, this attribute is on the <ConsumeInfo> element.
NetworkDelayMultiplier Specify the network delay multiplier (default = 100%) for a safety controller system. This value lets you reduce or
increase the connection reaction time limit in cases where the transport time of the message is significantly less or more
than the RPI. This may be the case when the RPI of an output connection is the same as that of a lengthy task period.
Type a percentage from 10...300, inclusive.
This attribute applies only to safety consumed tags.
For L5X, this attribute is on the <ConsumeInfo> element.
ReactionTimeLimit Specify the connection reaction time limit for a safety controller system. The Logix Designer application calculates the
connection reaction time limit as a function of the RPI, timeout multiplier, and network delay multiplier. The connection
reaction time limit is automatically recalculated if any of the above values change.
This attribute applies only to safety consumed tags.
For L5X, this attribute is on the <ConsumeInfo> element.
MaxObservedNetworkDelay L5X only. MaxObservedNetworkDelay is a measure of the longest time the data of a safety connection is delayed from
transporting the safety packets over the network. This attribute is exported for informational purposes only and is
ignored on import.
This attribute is on the <ConsumeInfo> element.
Unicast
For a safety consumed tag, specify if the EtherNet/IP connection is unicast. Specify yes for unicast or no to remain
multicast. For L5X format, specify true or false.
On export, only appears if the path to the producing module crosses an EtherNet/IP network and the producing module
supports unicast.
UnicastPermitted
For a safety produced tag, specify whether let the EtherNet/IP connection be unicast. Specify yes for unicast or no to
remain multicast. For L5X format, specify true or false.
L5X initial tag value
In an .L5X file, place the initial value of the tag in the Data element. See Chapter 1
Data Formats on page 39 for more information on Data elements.

If the tag is a string tag, specify a Format attribute.
