PROGRAMMING
REVIEWING W7600 PROGRAM
To review W7600 program information, press the RE-
VIEW key. With the cursor under PROGRAM, press the
NEXT (∨) key. Move the cursor under SETPOINT, TOD
or UNITS and press the NEXT (∨) key to view the desired
information. The REVIEW flowchart at the end of this
section provides the screens that can be viewed under each
of the main selections.
REVIEWING W7600 STATUS
To review W7600 I/O status information, press the
REVIEW key. With the cursor under STATUS, press the
NEXT (∨) key. Move the cursor under the desired input or
output to be reviewed and scroll through the screens, indi-
cating each output. If the last screen is being viewed and the
NEXT (∨) key is pressed, the S7600 will repeat the list and
wrap up to the first screen, as indicated in the REVIEW
flowchart at the end of this section.
ANALOG INPUT STATUS INTERPRETATION
• This display shows a positive or negative value with
engineering units +70.0°F (70°F).
• An analog point configured as a digital point may
show the condition of the point as either ACTIVE or
INACTIVE. Further interpretation of the configuration
data for this point is necessary because the active state
can represent an open or closed input.
• An analog input point that is short or open will report
the condition by displaying SHORT or OPEN.
• An analog input point that has a nonzero value be-
tween -.001 and +.001 will be displayed as UNDER.
Values that are greater than +9999 or less than -9999
will be displayed as OVER.
• If three asterisks (***) are displayed, the point is
configured but is not currently available. The usual
cause of this problem is the inability of the S7600A
Keyboard Display Module to read point status from
the W7600.
DIGITAL INPUT STATUS INTERPRETATION
• This display shows the status of the point, either
ACTIVE or INACTIVE. Further interpretation of the
point configuration data is necessary because the ac-
tive state can represent an open or closed input.
• If three asterisks (***) are displayed, the point is
configured but is not currently available. The usual
cause of this problem is the inability of the S7600A to
read point status from the W7600.
ANALOG OUTPUT STATUS INTERPRETATION
• This display shows a value in a percentage range from
0% to 100%.
• An analog output point configured as a digital output
point may show either ON (indicating the configured
100% output) or OFF (indicating the configured 0%
output).
• If three asterisks (***) are displayed, the point is
configured but is not currently available. The usual
cause of this problem is the inability of the S7600A to
read point status from the W7600.

DIGITAL OUTPUT STATUS INTERPRETATION
• This display shows the digital output point as either
being ON or OFF.
• If three asterisks (***) are displayed, the point is
configured but is not currently available. The usual
cause of this problem is the inability of the S7600A to
read point status from the W7600.
REMOTE ANALOG STATUS INTERPRETATION
• This display shows a positive or negative value with
engineering units +70.0°F (70°F).
• A remote analog point is configured as a remote digital
point as either ACTIVE or INACTIVE. Further inter-
pretation of the configuration data for his point is
necessary because the active state can represent an
open or closed input.
• If three asterisks (***) are displayed, the point is
configured but is not currently available. The usual
cause of this problem is the inability of the S7600A to
read point status from the W7600.
REMOTE DIGITAL STATUS INTERPRETATION
• This display shows the digital input point as either
being ACTIVE or INACTIVE. Further interpretation of
the point configuration data is necessary because the
active state can represent an open or closed input.
• If three asterisks (***) are displayed, the point is
configured but is not currently available. The usual
cause of this problem is the inability of the S7600A to
read point status from the W7600.
REVIEWING W7600 REVISION NUMBER
To review the status of W7600 component revisions,
move the cursor under the REV # selection in the review
mode display. After pressing REVIEW, the default posi-
tion of the cursor is under the I/O selection. Using LEFT/
RIGHT TAB (</>), move the cursor under the REV#
selection and press NEXT (∨). The revision numbers of the
S7600A Keyboard Display Module and the W7600G Con-
trol Module appear. The existence of a W7601A,B attached
to the W7600 is also acknowledged in this display.

W7601: None
ALARMS AND FAILURES
The W7600 detects two types of problems: alarms and
failures. Alarms are programmed by the user. Failures are
malfunctions that the W7600 automatically detects.
The W7600 maintains two alarm files: unacknowledged
and acknowledged. These files may contain both alarms
and failures. The unacknowledged alarm file contains alarms
and failures that have not been acknowledged by the user
from the S7600A Keyboard Display Module. The acknowl-
edged file contains alarms and failures that have been
acknowledged by the user.
The W7600 also provides an acknowledged alarm point
to notify the user of any existing unacknowledged alarms.
If there are any unacknowledged alarms, this point is turned
on. This point must be a configured digital output for
ALARM.
