800XA Advant master
I have Advant 410 controller safeguard system running on plant I ususally take bakup of source code through DUAP command.
Now i have a opputunity to load the application program.When i use LOAP command it gives message that should you want to delete all the PC programme.
I want to know should i type yes or no .
I just want to load the backup dump suource code into Advant 410 ?
You can compare DUAP/LOAP with using a drive imaging tool on the C:\ partition of a Windows computer (everything out/in, not regularly possible to change hardware).
To dump/load source code use the DUPCS/TRPCS commands. Source code format is interchangeable between different Advant/Master controllers.
For backup/restore purposes, the much faster DUAP command is preferred.
Loading a DUAP is only possible in empty controller in ECONFIG mode.
- A DUAP ( DUmp APplication) does NOT backup source code. It backs up the memory contents of the controller. This includes logical files from the database and the program tables of the PC programs as well as the "state" of the controller ( ie which programs were running, start values etc )
- A LOAP command restores the Memory contents into the controller again. The controller must be "clear" initialised before the backup can be restored using the LOAP command.
You can clear the controller by using the init switch or by using the "RECONFIG" control builder command. (ECONFIG to go into configuration mode and RECONFIG to restart the controller in clear mode)
Obviously, doing this deletes everything in the controller so isn't something anyone would recommend you do unless you actually need to.
