Logix Statistics
The Logix statistics are the statistics for connections and messages from the ILX56-PBS to
the Logix Controller. These are used when DPV1 messaging and alarming are mapped to
Logix tags.
Parameter
Description
Connection Failures
The number of failed attempts at establishing a class 3 connections with a
Logix controller.
Tag Not Exist Errors
The number of tag read and tag write transactions that failed due to the
destination tag not existing.
Privilege Violation Errors
The number of tag read and tag write transactions that failed due to a
privilege violation error.
This may be caused by the External Access property of the Logix tag being
set to either None or Read Only.
General Access Error
This statistic is used to indicate that the tag could not be accessed due to
a general error (eg. writing to a tag more data than the actual array size).
Message Retries
This count increases when no response was received from the Logix
Controller by the time the Message timeout is reached.
Message Failures
This count increases when the Message Retry Limit is reached and no
response has been received from the Logix Controller.
