Manual restore with PG5
PG5 can be used to write a valid program including configuration to the CPU
from the onboard flash. This function can be found on the "Online" menu within
the PG5 project manager or the online configurator:
●
Manual restore without PG5
If the "run/halt" switch is pressed for more than 3 seconds (while the PCD is in
a "Run" state), the user program will be loaded from the onboard flash.
During the "Copy Program from Flash..." operation, the Run/Halt LED on the
PCD flashes alternately red and green, and the Run and Halt LEDs also flash
alternately.
3.12.3 Transferring an application with flash card
With the flash card, it is possible to transfer an application from a PCD2.M5_ to
another controller of the same type:
●
On the source controller, copy the application to the flash card as described in
the preceding sections
●
Remove the supply to the source controller, and unplug the flash card
●
Send off the flash card where applicable
●
Insert the flash card into the target controller (which should be switched off)
●
Switch on controller.
●
Press "Run/Halt" switch for more than 3 seconds; the LEDs will flash while the
program is being copied from the flash card (control switches to "Halt" state)
●
Restart the control with the "Run/Halt" switch
If the configuration does not match the options available on the controller (e.g. IP
configuration on a controller without IP), the controller will switch to "Halt" state and
an entry will be written to history.
Loading the user program from the flash card will overwrite the user program backup
on the onboard flash, provided there is sufficient space for the program on the backup
flash.
