Type
Specifies the symbol variable type.
It is called "Symbol" which is freely named
to an individual address of the internal device of the display unit
or device/PLC address.
Select from [Bit Address] or [Word Address]. The total number of
symbols you can resigter is 1000.
It is called "Variable" when symbol was
mapped to the variable area prepared in the display unit.
When [Variable Format] is selected in the [Register Variable] in
the System Settings [Logic Program], you can use any name by
specifying a data format to the variable area. Select from [Bit
Variable], [Integer Variable], [Float Variable], [Real Variable],
[Timer Variable], [Counter Variable], [Date Variable], [Time
Variable], or [PID Variable].
The total variables you can register differs depending on the
model. (You cannot register variables on GP-4100 series or
GP-4*01TM.)

Variable Type
-
You can check the registration status of
variables by selecting the [Project Information] in the
[Information] from the [Project] menu and open the [Logic] tab in
the [Memory Usage], from the displayed dialog box and then click
[Details] from the [Variable Capacity].

When [Register Variable] is specified as
[Address Format] in the System Settings [Logic Program, use Bit
Addresses or Word Addresses only.
Array
Determines whether to specify arrays. Arrays provide you with a
method to manipulate multiple elements in a single variable. It
enables you to group variables with the same type and save it all
at one time.
Set up is possible when [Type] is [Bit Address], [Word Address],
[Bit Variable], [Integer Variable], [Float Variable], or [Real
Variable].
For more details, please refer to the following.
30.3.2.3
Arrays and Array Sizes
Array Zise
When [Array] is set, set its number of elements.
The range differs depending on the selected [Type].
Address
If you specified [Bit Address] or [Word Address] for [Type],
specify the Device/PLC address or the Internal Device Address.
Retentive
If you select a variable in [Type], specify whether to keep the
data of variable even if the display unit is turned OFF or reset.
Select [Retentive] to copy the data to the backup memory
(SRAM).
The number of variables set in the [Retentive] depends on the
[Retemtove Arear Settings] in the System Settings Window [Logic
