The 'Clone Unit' feature allows the user to clone the OCS of the exact same model. This feature clones the application program and unit settings stored in Battery backed RAM of an OCS into the Removable Media. It can then be used to clone a different OCS (of the exact same model and firmware level).
This feature can be used for:
Overview
The user needs to perform the following to Clone:
Open the System Menu of the OCS. Scroll to the bottom of the screen to highlight Clone Unit as shown below.
Selecting Clone Unit menu will open the following menu screen:
Clone Unit Menu before Cloning
Note: DSK - when selected shows number of total
and free bytes in Removable Media.
Free/Total - displays number of free and total
bytes in Removable Media
Make/Create Clone option enables user to duplicate / Clone application file, all unit settings and all register values from Battery Backed RAM.
After confirmation, the OCS will create two new files in the
root directory of the Removable Media Drive
as shown below:
AUTOLOAD.PGM Application file
CLONE.DAT File having all unit settings and
register values from Battery Backed RAM
NOTE: Make/Create clone operation automatically
includes the security in AUTOLOAD.PGM file for security enabled
files.
Once the cloning is successful, OCS gives a message as below:
Make/Create clone can also be triggered by setting %SR164.9 bit to "1" from within the program or via an onscreen graphics object.
Once the operation is completed, this bit is forced to zero by the firmware. When Make clone operation is triggered by this %SR bit, it does not require the user for confirmation for making clone. The success / failure of the operation is also not notified on screen to the user.
In the case of failure of "Make Clone" operation, %SR164.11 bit is set to "1" by the firmware.
NOTE: Backup of registers in FLASH memory is not performed by Clone Feature. (Fail Safe and Backup will be covered in the future)
Load Clone
This option loads the application, all unit settings and register values from Removable media to the Battery backed RAM (Regardless of AutoLoad settings) and then resets the OCS for the settings to take effect.
User needs to perform the following to Load Clone:
Once again select Clone Unit from main System Menu of the controller.
Then select Load Clone and OK to confirm.
After confirmation, all unit settings and register values will be loaded from Removable media to theBattery backed RAM (Regardless of AutoLoad settings) and then OCS resets for the settings to take effect.
NOTE: For security enabled files, Load clone
asks for password validation before loading the application. Load
clone can also be triggered by setting %SR164.10 bit to "1" from
Ladder program or graphics. Once the operation is completed, this
bit is made zero by the firmware. When Load clone operation is
triggered by this SR bit, it does not ask the user for confirmation
for loading clone. The success / failure of the operation is also
not notified on screen to the user. In case of failure of "Load
Clone" operation, %SR164.12 bit is set to "1" by the
firmware.
