-
If the GP-Viewer EX installation path is longer
than 80 single-byte characters, an error message displays
indicating GP-Viewer EX cannot start because its install path is
too long. Please reinstall GP-Viewer EX to an installation path
less than 80 single-byte characters.
-
You cannot install different versions of
GP-Viewer EX on one computer.
-
If you input the wrong key code, the key code
will not be set. Input the correct key code.
-
If you do not input key codes, the GP-Viewer EX
trial version starts up.
-
When connecting to the display unit without
setting up key codes in GP-Viewer EX, the GP-Viewer EX trial
version starts up.
-
Up to three units of GP-Viewer EX can access the
display unit at the same time. However, depending on the load, the
display unit may not support three GP-Viewer connections. Please
wait and try again. If you fail to connect several times, consider
looking at the design of the system.
-
Regardless of the number of connected display
units, you can display up to four windows of GP-Viewer EX on one
computer.
-
When starting GP-Viewer EX or clicking the update
button, the display unit and GP-Viewer EX display the same alarm
information. Subsequent alarm summary displays may differ between
the two, because the display unit and GP-Viewer EX monitor the
alarm information independently, depending on their communication
speeds
-
Because the display unit's external storage and
GP-Viewer EX's virtual external storage are not directly
synchronized, GP-Viewer EX cannot save alarm information.
-
When the sampling frequency is short, or the
timing for turning ON sampling's [Full Bit Address] is shorter than
the timing for refreshing GP-Viewer EX, the GP-Viewer EX screen and
display unit screen will be different because the system is unable
to get the XY Historical Scatter Graph's show/hide information in
time.
-
For errors that are automatically restored, such
as communication errors with a connected device/PLC, the display
unit may erase the error but the error remains in GP-Viewer EX. to
remove the error, either change screens or click the Close button
[x] in the system menu.
-
When multiple errors are triggered at the same
time, depending on the timing of when errors are received, all the
errors may not display.
-
As the screen does not rotate, the display unit
does not support portrait orientation.
-
When using symbol variables with a bit address
type, symbol variables with any element number other than 0 will
result in an error on GP-Viewer EX.
-
When writing to the following addresses in
GP-Viewer EX, the value is written to GP-Viewer EX's
#H_ChangeScreenNo system variable, regardless of the screen
mode.
-
[#INTERNAL]LS0008 (Direct Access Method)
-
[#MEMLINK]0015 (Memory Link Method)
-
System Data Area's [Change- to Screen]
address
-
In synchronous mode, GP-Viewer EX writes to and
reads from the display unit address. However, writes to and reads
from GP-Viewer EX addresses for system variables and clock
data.
-
In asynchronous mode, GP-Viewer EX writes to and
reads from GP-Viewer EX addresses. However, writes to and reads
from the display unit for the following addresses.
-
In the [System Settings] window's [Device/PLC]
page, when Indirect Devices are set up, internal device addresses
(LS area/USR area) other than the [Device ID Address]
-
Device/PLC addresses other than the System Data
Area's [Change- to Screen] address
