Issue:
What is a Unity Pro / Control Expert .DTX file?
Product Line:
Unity Pro, Control Expert, PLC
Resolution:
From the Control Expert menu: PLC - Save/Restore data between a file and the PLC
Data Transfer allows you to store the value of the following data in a file that can be downloaded to or uploaded from a PLC.
%M
%MW
unlocated variables
function block instances
Restoring data from a .DTX file is allowed even if the application has been built and/or data has been modified since 'Save Data from PLC to File' was performed.
(This is not possible if the data has been saved to a .DAT file. For this reason, we recommend saving to a .DTX file).
In order to 'Save Data from PLC to File', the following must be true:
- PLC has a project loaded.
- PLC is in RUN or STOP mode.
- Unity Pro is running and connected to the PLC
- The project is built and is EQUAL to the PLC.
In order to 'Restore Data from File to PLC, point to the .DTX file that was previously saved.
NOTE: I/O and Device DDT objects cannot be saved in DTX files.
SFC variables cannot be restored.
