Cloning a Controller

Cloning Procedure

Cloning the controller first removes the existing application from the target controller memory, if user access-rights are being copied to and enabled in the target controller. Refer to Clone Management.

Step

Action

1

Erase an SD card and set the card label as follows:

CLONExxx

NOTE: The label must begin with ‘CLONE’ (not case sensitive), followed by any normal character (a...z, A...Z, 0...9).

Select if you want to clone the Users Rights. Refer to the Clone Management subpage of the web server.

3

Remove power from the source controller.

4

Insert the prepared SD card in the source controller.

5

Restore power to the source controller.

Result: The copy starts automatically. During the copy, the PWR and I/O LEDs are ON and the SD LED flashes regularly.

Wait until the copy is completed.

Result: The SD LED is ON and the controller starts in normal application mode. If an error was detected, the ERR LED is ON and the controller is in STOPPED state.

Remove the SD card from the source controller.

8

Remove power from the target controller.

9

Insert the SD card into the target controller.

10

Restore power to the target controller.

Result: The paste starts automatically and the SD LED is flashing during this procedure.

11

Wait until the end of the paste:

oIf the SD LED (green) is ON, the cloning ended successfully.

oIf the SD LED (green) is OFF, and the ERR and I/O  LEDs (red) flash regularly, an error is detected.

oIf the SD LED (orange) is ON, the cloning is done with an error.

12

Remove the SD card to restart the target controller.

NOTE: When they are copied, access rights are only operational after a controller reboot.
