Preface
The Alarm Reference Message Guide contains listings of all the process
and system related alarm messages you are likely to encounter in the
operation of a maxDNA system.
Part I of this publication introduces you to all the maxDNA alarm types,
alarm-related displays and alarm message formats appearing on displays
and on hard copy reports.
Part II provides a complete alphabetized listing of all the maxDNA
process alarm messages along with text explaining what they mean. Part
III provides a similar listing for system alarms.
This publication assumes you are familiar with the maxSTATION and
the various display environments.
For more information about related topics, refer to the following

Introduction
maxDNA System Alarm Classes
maxDNA System lets you view two classes of alarms:
Process Alarms
System Alarms
Process Alarms
Process alarms consist of alarm messages associated with the process
itself. These consist of two types:
Process Limit Alarms
Process limit alarms are caused by values exceeding their
assigned limits. Alarm information consists of time, point
tagname and its long description, alarm text associated with the
alarm, current value of the point, alarm limit value, and the units
of measure for the point in alarm.
Process Status Alarms
Process status alarms are generated by points and programs atDPUs. Alarm information consists of time, point tagname and its
long description, alarm type text and the alarm value.
System Alarms
8/6/2019 Alarm Messages A1

maxSTATION Installation
tagname of the station reporting the alarm, the device reporting
the fault, and the alarm text.
DPU Bus Network Diagnostic Alarms
This relates to two classes of alarms, DPU Bus related and
maxNET network related. DPU Bus network diagnostic alarms
are caused by cable breaks, token passing errors, failure of
stations to respond, etc. maxNET Network alarms are caused by
Frame Switch or hub failures, Ethernet card failures, Ethernet
cable breaks, or a failed target maxSTATION.
Alarm information consists of time, tagname for the DPU Bus
reporting the alarm (e.g. DPUBUS1), name of the maxSTATION
involved in the fault, and the alarm text.
Alarm Configuration
You may set up alarms and events to be detected when you create
configurations using maxTOOLS. The system then automatically detects
the alarms and events, processes them, and identifies them for display
and acknowledgment, logging, analysis, and optional archiving.
Configuring Alarm Priorities
At time of configuration, you may give alarms one of six severity levels.(0 is the lowest prioritynot alarmed at alland 5 is the highest
priority.) Alarm severities can be used in conjunction with a temporary
filtering function that you may configure using maxVUE Runtime to
further classify, filter, and sort alarms for a more meaningful presentation
of alarm conditions on alarm-related displays. See "Alarm Summary
Display" for a listing of other filtering categories.
Viewing Alarm Messages
You may view alarms from the following standard and custom
maxSTATION displays:
8/6/2019 Alarm Messages A1

Introduction
Custom graphic displays
Alarm Summary Display
The Alarm Summary display shows filtered or unfiltered alarms from all
maxDPUs and DBMs in the domain and the local LSS. By default, a
single Alarm Summary page displays up to 20 alarms, however, the
window may be configured to display from 1 to 40 alarms; display
buttons let you page up and down through the full list. There is no limitto the number of pages. Older systems with only DBMs would have a
limit of 5000 alarms per DBM.
Click the Alarm Summary button on the Vertical Toolbar or on the
Operator keyboard to access the display in a single keystroke. Each entry
on the display lists the time, date, tagname, long description, value, limit,
and acknowledge status of the alarm. Points may be selected in the
summary for display swap or control action. When selected, the tagname
of the selected point will appear on the Point Select button on the
Horizontal Toolbar display.
Note: By default, the Alarm Summary display lists all alarms without
filtering. Use the Temporary Filter Setting Display to set up and control
how alarms are seen on the actual Alarm Summary displays.
You may filter alarms by type, the state of acknowledgment, and theseverity. See Publication 278599, maxSTATION Operator's Guide,
"Filtering Alarms."
Alarm Summary Menu Buttons
The Alarm Summary Display includes six buttons at the bottom of the
display that let you view alarms filtered by various categories that you
select from the Temporary Filter Setting dialog box. See Publication
278599, maxSTATION Operator's Guide, "Temporary Filter Setting."Table 1-1 relates the available filtering categories to maxDNA alarm
classes as described at the beginning of this chapter. You may click the
following buttons to display a filtered alarm list:

Alarm List Display
The Alarm List display shows the most recent acknowledged and
unacknowledged alarms (with the highest severity). By default, the
Alarm List displays up to 20 alarms, however, the window may be
configured to display from 1 to 40 alarms; the alarms appear inside awindow at the lower part of the Vertical Toolbar.
Because the Alarm List remains on the Vertical Toolbar display, you
never lose sight of highest priority alarms. Unacknowledged alarms are
displayed in their corresponding alarm severity color combination;

Introduction
Acknowledging and Silencing Alarms
With only a single keystroke, you may acknowledge alarms using the
operator keyboard, the PC keyboard and from a variety of maxVUE
Runtime Displays at the maxSTATION.
Using Keyboard Buttons
The four alarm keys, colored yellow on the maxDNA operator keyboard,control alarms. Two of these keys, and , also
appear on the standard Horizontal and Vertical Toolbar display. Use
these keys as follows: to temporarily stop alarms from occurring,
, restore their function (remove defeat), ,
acknowledge them, , and silence the audible annunciator,
.
The Acknowledge, Silence, Defeat and Restore keys work in maxDNArelease versions 3 and 4 but are restricted to the selected point and the
selected point must have a Point Control pop-up on the screen.
Acknowledge and Silence
Press the key to acknowledge the highest priority
unacknowledged alarm; this is the top alarm displayed in the alarm list
display on the Vertical Toolbar display. This key has the same effect asthe Ack button on the Alarm List display. On the PC keyboard, the
equivalent key is .See the next section.
When a new alarm is detected, the maxSTATION can sound an audible
alarm in addition to posting the new alarm in the appropriate location in
the alarm list.The key lets you quiet the alarm with a single
keystroke and has the same effect as the Silence button on the Vertical
Toolbar display. See "Using maxVUE Runtime Display Buttons". On
the PC keyboard, the equivalent key is
The key only silences an audible alarm; the
key both silences and acknowledges the top most alarm on the list.

Restore
Restores all alarms on the currently selected block so that it can alarmagain. On the PC keyboard, the equivalent key is . See next
section.
Defeating and Restoring Alarms
You may temporarily defeat Control and Data Block alarms withoutchanging their triggering criteria. This permits individual process loops
and other control actions to be switched off during operating periods
when the alarm would be of no use. An example of this would be
nuisance alarms that occur during startup or changes to part of the
system. When normal operation resumes, the alarm features of that
function can be restored.
The Defeat capability eliminates clutter in alarm summaries and
operating views, simplifying the operator's view of the process. To besure operators do not overlook defeated alarms, the word defeated
appears in every faceplate, which displays that loop or controls action.
Note: You may only defeat process-related points; alarms related to
system hardware points cannot be defeated.
Using maxVUE Runtime Display Buttons
From maxVUE Runtime displays, you may acknowledge and silence
alarms from the standard Vertical and Horizontal Toolbars, Alarm
Summary Display, Alarm List Display, and from Point Control pop-ups
and digital Detail Displays. Refer to the following table:

The audible signal indicates
that an alarm has occurred for
a point assigned to a pre-
defined hierarchical group.
* If an audible alarm is equipped, this action will silence the audible alarm.** The Silence key only silences an audible alarm;the Acknowledge key both
silences and acknowledges the top most alarm on the list. maxSTATIONs notequipped with sound boards and speakers may be configured to silence alarms
occurring at a maxSTATION playing the sound.
Note: Because and buttons, and the Alarm
List window appear on the standard Vertical and Horizontal Toolbars,
you may place these elements on every screen view in the system, ifdesired.
You may select individual alarms on the Alarm Summary display by
pointing to an alarm and clicking the left mouse button. In response, the
system displays the point tag name at the bottom of the display. Once
selected, the point can be acknowledged via the Ack point button.
Additionally, the Point Data, Control and Detail buttons will apply to the
selected point.

Chapter 2
How to Interpret
Process Alarms
A process alarm indicates that some portion of the process has gone
beyond its specified limits. When a point goes into alarm, the system
adds its tagname to the Alarm List and Alarm Summary displays, and
indicates the alarm condition on appropriate point-related pop-updisplays.
Each of the standard maxDNA functional blocks stored in the DPU
database has many alarm states and control conditions built into them,
which are set during the configuration process. This permits alarming
capability and an interlocking capability with other user-ready and user-
defined blocks.
Control Block Alarms
Control Blocks, stored in the DPU (DPU4A and earlier), can contain up
to 16 independently adjustable alarms, which permit alarming and
interlock capabilities not only within the specific block originating the
alarm but also in other computational blocks. The PID Control Block, for
example, will alarm and set triggers (Alarm/Mode Word bits) forinterlock upon the following six conditions:
Process Variable HI Setpoint LO
Process Variable LO Deviation HI

How to Interpret Proc ess Alarms
Analog input alarms can help discriminate between reaching an
operational and safety alarm condition and the failure of an input device,
such as a field sensor/transducer or the loss of an I/O module or channel.
Data Block Alarms
The DPU 248 Data Blocks each have the same eight input alarms listed
for the High Level Analog Inputs. This allows the same alarms to be
applied to other inputs by linking them to a Data Block. In addition, Data
Blocks can each be used to perform any of the following alarm options:
Open thermocouple detection.
HI and LO alarm condition.
HI-HI and LO-LO alarms expressed either as an absolute value
or as a delta from the HI or LO alarm value.
Rate-of-change alarms and rate-of-change clamps placed on
inputs or outputs to detect unacceptable slew rates or to limit signal
slew rates.
Adjustable hysteresis (% value) deadband for value-related
alarms (HI, LO, HI-HI etc.) to prevent nuisance alarms as a variable
hovers around an alarm trip value.
Time Delay settings to suppress transient swings into alarm but
not sustained alarm conditions.
Alarms built into each Data Block can be set up to trigger:
On single threshold crossing or on repetitive deltas.
Upon return to normal.
If acknowledged, but situation remains uncorrected for too long
a time period.
Alarms can also automatically acknowledge when they return to normal
before being acknowledged by the operator. These options enable the
i l b l di i hil

HI alarms, rising/falling, or all alarms. Cutout can be due to process
value changes or system hardware conditions. For example, during
known disruptive operations (start up or shut down), selective alarms canbe temporarily disabled to avoid masking more important real alarms.
Yet you will be kept aware of other conditions of that same bypassed
point, such as an open thermocouple.
These alarm cutouts are independent of the Alarm Defeat/Restore
mechanism, and can be triggered either by operator command, by a
discrete signal, or induced by a program.
Any event, threshold of analog value, lapse of time, condition, state,sequence step (or completion) or command either within or outside of
maxDNA can be used to trigger an alarm cutout.
A single event or logic result of several conditions or events (boolean
expression) can impact the alarm of a single Data Block, or any
combination of Blocks. Each Data Block can have its own independent
triggering circumstance.
Troubleshooting Process Problems
Process limit alarms and process status alarms appear together on the
Alarm Summary display mixed in with system alarm messages. The
format of displayed process alarms is somewhat different from the format
for station alarms and DPU Bus network alarms. (Refer to Chapter 3,
"How to Interpret System Alarms" for a description of system alarm
formats.)
Process limit alarms have the following format:

Variable Character Lengths
Note: The Limits field does not apply to
status alarms.
Displayed process limit alarms and process status alarms are also
somewhat different from each other. Process limit alarms report:
Time the alarm occurred.
Tagname of associated point.
Name of point and alarm message text under the Description
field.
Alarm type.
Current value of the point.
Alarm limit value.
Units of measure for the point.
The process status alarms format is similar to the process limit alarms
format as outlined above; however, because status alarms are associated
with digital type points, the Summary Display Limits field does not
apply and is not used.
Process alarm messages also appear in a hardcopy version that uses a
format somewhat different from the Alarm Summary Display format.
Because the printed format can accommodate 133 characters per line,printed text may contain additional information. Refer to the following
figure to learn how to recognize logged process alarms:

such as a mode change or a configuration. When a Edit Action is logged,the characters ea appear.
Tagname
Tagname of associated point; the tagname is created when you
configure a point using maxTOOLS.
Alm/clr
When an unacknowledged process alarm is logged, the characters alm
appear in this three-character wide field. If the alarm is acknowledged
or otherwise clears, the characters clrappear. If the line applies to an
edit action, the field is blank.

Process Alarm message text, such as HiHi LoLo; Range High; and so
forth.
When this field applies to an edit action, the message text describes an
attribute that was edited.
Value Limit
When this field applies to a process alarm, it reports the current value
of the point and the alarm limit value.
When this field applies to an edit action, it reports that the limit was
changed; the new limit value along with the previous value limit
appear in this field.

System and Network Alarms
System diagnostic status alarms inform you of maxDNA system
hardware and software problems. Problems detected within a specific
module or station are classified as diagnostic failures. Problems withcommunications are referred to as highway network alarms. DPU Bus
network alarms are further divided between DPU Bus network and
maxNET network communications problems. maxVUE Runtime System
Status displays show both alarm types.
System alarms appear along with process alarms on the Alarm Summary
Display and on the Alarm List. The format of displayed system alarms is
somewhat different from the format for process alarms; refer to the
previous chapter for a description of process alarm formats.
System alarms have the following format:
Time Date Tagname Text
Subsystem Name Message TextHH:MM:SS MM:DD:YY Up to 16

On the display, the subsystem reporting the fault and the message text
appear together under the Description field. The three fields to the right
of this field Type, Value, Limit apply to Process alarms.
System alarm messages also appear in a hardcopy version that uses a
format somewhat different from the Alarm Summary display format

maxSTATION, DPU, I/O module, or DPU Bus reporting the problem.
If you have a particularly large configuration consisting of multiple DPU
Buses and many stations configured with each DPU Bus, system status
displays may also help you to pinpoint the location of a system problem.
System status displays are a collection of screens used to diagnose
problems in your system. These consist of:
System Status Display
DPU Bus Map Display
DPU Bus Statistics Display
DPU Bus Station Status Display

Part II consists of an alphabetic listing of all maxDNA Process Alarm
messages. The following pages contain the actual message text
(appearing here in all upper case characters), the point or points which
can generate the alarm, and a description of what each process alarm
message means.
Process alarm message text for any given point appears in three versions:
16-character text used in alarm log
12-character text used in Alarm Summary displays
12-character text used in Detail pop-ups
All three versions are listed for each process alarm message entry.
Note: Points for which an alarm message is applicable include some
Control Blocks, which are no longer supported by maxDNA, but were
supported by the Models 582 and 585 Operator Stations. Those points
are identified using ** in the table.

DPU4E/DPU4F Process Alarms
Process alarms in a maxDPU are generated by three types of atomic
blocks: ATAG, DTAG and ALMREP. ATAG and DTAG will generate
specific alarm text strings for the alarm summary display and events.
These texts are shown below. Names in capital letters below are
attributes of ATAG and DTAG.
Alarm Clear Value = (TMSG attribute value) DTAG
TMSG is set to TRTXT or FLSTXT based on the value
of OUT in the DTAG. A clear alarm occurs when the
DTAG output value changes to the non-alarm state.
Alarm Digital Value = (TMSG attribute value) DTAG
TMSG is set to TRTXT or FLSTXT based on the value
of OUT in the DTAG.
Return to Normal DTAG, ATAG
Return to Normal behavior must be selected in the
ALMBEHAVE attribute. A return to normal alarm
occurs when the alarm condition of an acknowledged
alarm clears.
AlarmRising =ACTUALRATE Lim=LIMRATE ATAG
LIMRATE attribute must be non-zero for a rising or
falling alarm to occur.
AlarmFalling =ACTUALRATE Lim=LIMRATE ATAG
LowAlarm Limit =LIMLO Value =OUT ATAG
HighAlarm Limit =LIMHI Value =OUT ATAG
LoLoAlarm Limit =LIMLOLO Value =OUT ATAG
HiHiAlarm Limit =LIMHIHI Value =OUT ATAG
Workstation Alarms

Workstation Alarms
DPU4E/DPU4F System Alarms
The maxDPU produces several system alarms. ATAG can produce an
open circuit alarm when referenced to a TC. The base DPU atomic
blocks will produce the others.
TC input# ADDR nnn Open Circuit ATAG
Input# is the TC input referenced by the ATAG.
nnn is the address of the TC card. This alarm is
generated by ATAG but actually occurs due to a break in
the wiring for a TC input.
Standby DPU has Failed BACKUP
This occurs in DPU4E only and is somewhat misleading.
This alarm is generated in the active DPU that has just
taken over due to a takeover request or failure of the
(previously) active DPU.
Primary/Secondary DPU Takeover BACKUP
DPU4F only. This alarm is generated when the inactive
DPU changes it state to active due to a takeover or a
failure of the (previously) active DPU.
Normal Queue Overrun QUEOVRN
The normal time class typically executes every 500 ms
in a DPU. If it cannot complete execution of all of the
normal time class atomic blocks in the configured time
period, this alarm is generated. While this alarm should
be very rare, it indicates a fairly serious condition. TheDPU is overloaded to the point where it cannot perform
control and monitoring functions in a timely manner.
Prompt attention should be given to the size of the
configuration and to the allocation of atomic blocks to
the critical, high and normal time classes. For example,
maxSTATION Installation
8/6/2019 Alarm Messages A1
30/74
maxSTATION Installation
DPU4F set to 10 MB operation when connected to a 100
MB port will generate a NetErr alarm.
DPU Battery Problem BATALARM
DPU4E only. Generated when the battery voltage is
determined to be too low to sustain DPU operation long
enough to write the configuration to flash memory.
DPU CPU Fan Problem FANALARM
DPU4E only. The CPU fan has stopped or slowed to thepoint where it is no longer effective. The fan should be
replaced.
WorkStation Alarms
A number of programs in the workstation can produce alarms. The name
of the originating program is shown on the right. The text on the left will
appear in the Text field on the alarm summary display. All workstation
alarms are of type System.
[IP address] DPU is Not Responding Healthlog
Healthlog cannot establish communication with theDPU.
[IP address] Status: SBP_E_TIMEOUT Healthlog
Healthlog has lost communication with a DPU.

AP CANNOT COMMUNICATE ON
NETWORK A
APPL An Applications Processor has lost communications with
a Real-Time Processor on Network A. Real-Time
Processors regularly broadcast their status on both control
room networks. All Graphics Processors will receive all
Real-Time Processor broadcasts, even if the Graphics
Processor and Real-Time Processor are in different
domains. When a Graphics Processor ceases to receive a
broadcasts from a Real-Time Processor on this network, itgenerates this alarm. This situation may be caused by any
number of failures, such as a bad Ethernet card A in the
Applications Processor, a bad cable, a bad Ethernet card A
in the Real-Time Processor, or a failed Real-Time
Processor.
APPLICATIONS PROCESSOR SWITCHED
SERVERS
APPL The Applications Processor has either lost Control Room
Network communications with its current Real-Time
Processor or has determined that a different Real-Time
Processor in the same domain has a better data highway
status. This is a one shot alarm and does not persist.

APPL An Applications Processor has lost communications with a
Real-Time Processor on Network B. Real-Time
Processors regularly broadcast their status on both control

broadcast from a Real-Time Processor on this network, it
generates this alarm. This situation may be caused by any
number of failures, such as a bad Ethernet card B in the
Applications Processor, a bad cable, a bad Ethernet card B

APPL GP A Graphics or Applications Processor is currently
using a Real-Time Processor as a data server and that
Real-Time Processor is not on its preferred server list.
This alarm will persist until the station starts using a
preferred Real-Time Processor as its current server.
The switch to non-preferred server can happen either
as a result of failure of all preferred servers, or manual
switch via the RTP Selection Display.
CURRENT YEAR IS OUT OF CONFIGURED

respond to a highway request; but, after a timeout period,the CP had not responded.
DMA TIMEOUT ON NETWORK SCSI
OPERATION
RTP There is a fault in the SCSI bus of this WorkStation: a
DMA operation was not completed within the required
timeout period. The most likely reason for this error is that
some Graphics Processors in this WorkStation have the
same SCSI ID (look at CONFIG.INI in the \VUE
subdirectory to see). There may also be a hardware fault
such as a lose SCSI connector, a defective SCSI cable, etc.

LOSS OF COMM WITH A GRAPHICS
PROCESSOR
RTP This Real-Time Processor could no longer communicate
with one of its client Graphics Processors. The RTP's
timesync function generates this alarm if each GP does not
periodically issue time sync requests. This can be an
Ethernet communications problem, or a failure of a
Graphics Processor. This is a one-shot alarm and does not
persist.
