Since the memory table is allocated
to the host memory, the display is
updated in accordance with the
contents of the host memory.
The battery voltage has dropped and
the data in the memory table has
been destroyed.
Since ON is set for the resume
function, the initial values of the
screen data memory are not written
to the memory tables.
Two words have been set in a
numeral memory table for an indirect
address for a number/text display.
Malfunction due to external noise
There are too many numeral/text
displays on the displayed screen.
The cycle time is extended due to
heavy processing at the host.
In an RS-422A/485 connection,
there is illegal branching or an
erroneous terminator setting.
The quantity of read data exceeds
the stipulated restriction.
The total of the element coefficients
for the displayed screen is greater
than 1024.
Since the data is transmitted from
the host in screen units, the number
of elements on the overlapping
screen has exceeded the maximum
permissible without being checked
by the Support Tool.
Display System Menu under Change
System Settings in the System
Installer mode is set to Disabled.
Screen Memory Protect under
Change System Setting in the
System Installer mode is set to
Disabled.
Screen Memory Protect has been
set to Disabled because the PT
power supply was turned OFF during
deletion of screen data.

Reduce the number of numeral/text displays on the
screen for which updating is delayed.
Shorten the host cycle time.
Wire correctly. (Refer to Connecting to the Host
from the RS-422A/485 Port in section 5 in the Setup
Manual .)
Check the maximum number of elements by
referring to Display Restrictions (page 425), create
the screen data again, then transmit all of the
screen data in a batch to the PT.
Check the maximum number of elements by
