Fig. 5.8 Network variables for master interface
Network variables and their references are deleted in the same way as standard variables
(sect. 5.3).
For more details about network variables for master interface see sect. 4.3.3.1.
If the interface is configured as a Slave, all network variables to be requested by the mas-
ter are shown in one list (Fig. 5.9). For more details about network variables for Slave in-
terface see sect. 4.3.3.3.

5.6 Copy / paste variable block
The variable blocks can be copied and pasted into another project.
To copy a variable block, select it in the workspace and use the toolbar icon or the
item Copy in the block context menu.
To paste a variable block into another project, open it in the second ALP instance and
use the toolbar icon or the item Paste in the workspace context menu.
Copy rules for all variables associated with the block:
 If the variable associated with the block is unique in the second project, it will be
added with all properties to the variable table.
 If there is an identical variable in the second project, it will be associated with the
pasted block. No new variables will be added to the variable table.
 If the second project has a variable with the same name but different parameters, a
new variable will be created. To resolve the naming conflict, the name of one of the
variables should be changed manually.
 It is not possible to insert variables of REAL type into a project for a target device that
does not support REAL data type.
 Retain (persistent) variables cannot be copied into a project for a target device that
does not support them.
Copy rules for service variables:
 Service variables cannot be copied to a project written to a target device without a
real-time clock.
