Cause: The CMOS variable that you attempted to delete was created This could also be because a KAREL program, Network or KCL was adding deleting or doing a node operation when access was attempted Remedy: Delete the variable in the same start mode that the variable was created. For example if a CMOS variable was created at CONTROLLED start it must be deleted at CONTROLLED start. If it is because of some access conflict the attempt the operation again when no other variable accesses are in progress.
