Logic Program
Select whether to [Enable] or [Disable] the logic features.
Register Variable
Select [Variable Format] or [Address Format] to register an
address.
Retentive Area Settings
Click [Retentive Area Settings] to display the [Retentive Area
Settings] dialog box.
The retentive/volatile points can be specified for symbol
variables in [Variable Format]. The retentive/volatile ranges can
be specified for symbol variables in [Address Format].
You can specify only the variable points for
retentive/volatile.
You can configure the retentive/volatile settings individually
in the [Symbol Variable] window, the [Address] window or
[Properties] after creating a new variable.
Please note that this setting is volatile when creating a new
variable.
For each address, specify the retentive/volatile range. With
this setting, all the addresses within the retentive area will be
retained, and the address values within the clear area will not be
retained.
Please note that all the variables allocated to I/O (X, Y, I, Q)
will be set to volatile. You cannot change the settings to retain
variables between sessions. Furthermore, you can only choose the
retentive setting for PID Variables (U).
