ESP-DDS2-x (Global Drive PLC Developer Studio V2.3)
Eliminated function restriction:
If the following warning is indicated when compiling a DDS project:
Warning 2903: A user code is using an unknown unit: <>
DDS does not crash after the compiling process has been finished.
In order to eliminate this warning use the Instance Parameter Manager (register card Resources) to assign a unit to every code which does not have a unit (see column unit).
For this, select the corresponding code and open the menu item Insert>Edit object.
Select the unit desired from the selection list offered by the 'Unit' field and click on <OK> to confirm the entry.
Save the project when every code has been assigned to a unit.
