US 11,376,728 B2 · Method of handling safety, control system and industrial system

Abstract

A method of handling safety in a working area of an industrial system, wherein at least one machine is arranged to operate in the working area, at least one manually operable safety input device is provided in the working area, and one or more of the at least one machine and the at least one safety input device is movable to different positions in the working area, the method including continuously or repeatedly determining whether one or more of the at least one the machine is in proximity to one or more of the at least one safety input device; and associating at least one machine with the at least one safety input device upon determining that one or more of the at least one machine is in proximity to one or more of the at least one safety input device, such that the at least one associated machine can be brought to a safe state by means of the at least one safety input device.

A method of handling safety in a working area of an industrial system, wherein a plurality of machines are arranged to operate in the working area, at least one manually operable safety input device is provided in the working area, and one or more of the machines is mobile and movable to different positions in the working area, the method comprising:

continuously or repeatedly determining whether one or more of the machines is in proximity to one or more of the at least one safety input device;
and
associating a plurality of machines with at least one safety input device upon determining that a plurality of the machines are in proximity to one or more of the at least one safety input device, such that the plurality of associated machines can be brought to a safe state by means of the at least one safety input device.

A control system for handling safety in a working area of an industrial system, wherein a plurality of machines are arranged to operate in the working area, at least one manually operable safety input device is provided in the working area, and one or more of the machines is mobile and movable to different positions in the working area, the control system comprising a data processing device and a memory having a computer program stored thereon, the computer program including program code which, when executed by the data processing device, causes the data processing device to perform the steps of:

determining whether one or more of the machines is in proximity to one or more of the at least one safety input device;
wherein the computer program comprises program code which, when executed by the data processing device, causes the data processing device to perform the step of:
associating a plurality of machines with at least one safety input device upon determining that a plurality of the machines are in proximity to one or more of the at least one safety input device, such that the plurality of associated machines can be brought to a safe state by means of the at least one safety input device.
