The following table lists the most common mistake conditions that
can occur on a PanelView terminal.
Mistake Message Cause What to do:
Alarm History print ignored—a previous request is
already queued. You have requested a print-out of the alarm
history while one is printing. Wait for the alarm history print-out to
complete before requesting another.
Alarm message print ignored—queue is full of
previous requests. The terminal is sending alarm messages to
the printer faster than the printer can
process them. Decrease the rate at which alarms are
generated. Use higher baud rate to printer.
Alarm Status print ignored—a previous request is
already queued. You have requested a print-out of the alarm
status while one is printing. Wait for the alarm status print-out to
complete before requesting another.
Control Byte location does not lie within the
specified module group range. The module group chosen in the Control
Byte is outside of the rack definition. Expand the rack definition to include the
Control Byte module group, or change the
Control Byte location to be within the
specified module group range.
Current operation failed. Memory card is
write-protected. The memory card is write-protected. Remove write-protection (move the tab)
from the memory card.
Cursor Control Value corresponds to a skipped
state value. The value of the Cursor Control matches a
skipped state in the cursor list. Check that the state values for the cursor
list are configured correctly and the PLC
program is using the correct values.
Cursor Control Value does not correspond to a
configured state value. The value of the Cursor Control does not
match any of the configured cursor list state
values. Check that the state values for the cursor
list are configured correctly and the PLC

properly connected and the printer is online.
