Description:
A Digital Alarm (ALMD) configured to trigger when the input condition of the alarm is false does not
trigger if the alarm condition is false when you conduct a download or return to Run mode.
When the Condition parameter of the ALMD instruction is not set (that is, Input = 0) and either the
program has recently been downloaded to the controller, or the controller has been changed from Run
to Program and back to Run mode, the alarm is not activated (that is, the InAlarm bit is not set).
These behaviors may result, depending on your application:
• Programming designed to respond to the activated alarm is not executed.
• Messages designed to be indicated at the operator station in response to the activated alarm are
not indicated.
• The alarm’s history log does not indicate that the alarm was activated.
If you choose not to upgrade to this revision, you must toggle the Condition parameter from set (that is,
Input = 1) to not set (that is, Input = 0) to activate the alarm.
If your Condition parameter is set, then the alarm activates as expected after you download or change
the controller mode.
This publication describes enhancements and anomalies (known and
corrected) for ControlLogix controllers, revision 16.
Information that has been added or changed since the last revision of this
publication is indicated by a change bar as shown to the right of this
paragraph.
In addition to information specific to the most recent firmware revision, the
information from previous minor revisions is retained in these release notes.
We strongly recommend that you review the information provided regarding
previous firmware revisions. We recommend that you do so because, if you are
upgrading your firmware through multiple previous revisions, all of the
information specific to all of the revisions is applicable.
For example, if you need to upgrade your 1756-L61 controller from revision
16.007 to 16.021, all of the information specific to revisions 16.007, 16.009,
16.020, and 16.021 is applicable.
