Abstract
A node for wirelessly controlling devices of a collaborative device group in an industrial infrastructure. The node includes: an inspection unit configured to identify a packet data flow of packet data to be transmitted by the node to one of the devices of the collaborative device group to control the corresponding, respective device; and a scheduling unit coupled to the inspection unit. The scheduling unit is configured to schedule transmission of the packet data to the corresponding, respective device based on the identification, by the inspection unit, of the packet data flow.
Claims25
A node for wirelessly controlling devices of a collaborative device group in an industrial infrastructure, the node comprising:
- a processor and a memory forming:
- an inspection unit configured to identify a packet data flow of packet data to be transmitted by the node to one of the devices of the collaborative device group to control the corresponding, respective device;
- a scheduling unit coupled to the inspection unit, the scheduling unit is being configured to schedule a transmission of the packet data to the corresponding, respective device based on the identification, by the inspection unit, of the packet data flow, the node being configured to determine an operating dependency between the devices, and the scheduling of the transmission of the packet data to the corresponding respective device being based on the operating dependency;
- and
- a programmable logic controller coupled to the scheduling unit via the inspection unit, the programmable logic controller being configured to control the devices of the collaborative device group through control frames, and the node being configured to determine the operating dependency between the devices based on an inspection of a source address of the control frames.

A system comprising two or more nodes, each node wirelessly controlling devices of a collaborative device group in an industrial infrastructure, each node comprising:
- a processor and a memory forming:
- an inspection unit configured to identify a packet data flow of packet data to be transmitted by the node to one of the devices of the collaborative device group to control the corresponding, respective device;
- a scheduling unit coupled to the inspection unit, the scheduling unit being configured to schedule a transmission of the packet data to the corresponding, respective device based on the identification, by the inspection unit, of the packet data flow, the node being configured to determine an operating dependency between the devices, and the scheduling of the transmission of the packet data to the corresponding respective device being based on the operating dependency;
- and
- a programmable logic controller coupled to the scheduling unit via the inspection unit, the programmable logic controller being configured to control the devices of the collaborative device group through control frames, and the node being configured to determine the operating dependency between the devices based on an inspection of a source address of the control frames:
- each of the nodes being configured to transmit packet data to one or more corresponding, respective user equipments via which the system controls the devices of the collaborative device group.
