The method involves manually controlling a manipulator i.e. six axis industrial robot (1), by a low safety level personal computer (4), which is connected to a control cabinet (2) of the manipulator. A permissible state is monitored by a higher safety level protective device e.g. safety fence (3), safety door (3.1) and make contact (3.2), which is connected to the cabinet. An action prescribed by the personal computer is executed by the manipulator until the protective device communicates the permissible state to the cabinet, where the action includes movement of the manipulator. Independent claims are also included for the following: (1) an arrangement for safely controlling a manipulator (2) a computer program having instructions for safely controlling a manipulator (3) a computer program product having instructions for safely controlling a manipulator. |
