Command ‘Reset origin’¶

Function: This command resets all variables of the active application (including the remanent variables) to their initialization values and deletes the application program from the PLC.

Call: Menu bar: Online .

Requirement: The application is in online mode.

Reseting deactivates the breakpoints currently set in the project. If you execute this command when the program is halted at a breakpoint, then you will be prompted whether the current cycle should really be ended. Alternatively, CODESYS executes the reset immediately. However, not all runtime systems are able to perform a reset without first ending the current cycle.

Hint

If a safety controller is inserted below a PLC, then this command can permanently interrupt the communication links of the safety controller to other safety controllers (via safety network variables), to field devices, and to the development system. The safe field devices and the other safety controller can enter the safe state as a reaction. The connection to the development system is affected only in the case of a safety controller that is connected to the main controller via a fieldbus. For more information, refer to the section “Subordinate Safety Controllers”.
