FB_ControlClone: Clone the Controller

Function Block Description

Cloning is by default possible by SD card or Controller Assistant. When user rights are enabled and the View right ExternalCmd is denied for the ExternalMedia group, the cloning function is not allowed. In this case, the function block enables cloning functionality one time on the next controller power on.

NOTE: You can choose whether user rights are included in the clone on the Clone Management page of the Web server.

This table shows how to set the function block and the user rights:

Function block setting	When user rights enabled	When user rights disabled
xEnable = 1	Cloning is allowed	Cloning is allowed
xEnable = 0	Cloning is not allowed	Cloning is not allowed
