A method for reducing interference between wireless networks for industrial devices. The method includes the steps of: obtaining a first resource schedule of a first wireless network manager; obtaining a second resource schedule of a second wireless network manager; determining whether there are resource conflicts between the first resource schedule and the second resource schedule; and providing, when at least one resource conflict is determined, a new wireless resource schedule for the first wireless network manager to avoid at least part of the determined resource conflicts. A corresponding multi-network manager, system and computer program product are also presented.

Multi-network manager, method and system

An industrial process control system including a process control device, a first wireless communication network, a second wireless communication network and a first group of wireless field devices interfacing the industrial process and being associated with the first network. The network supervisor device investigates if the field devices of the first group are able to communicate with the process control device via the first network while meeting a communication restriction requirement, and redirects, in case the requirement is not met, communication between some of the field devices in the first group and the process control device to the second network so that the requirement is met for a first part of the field devices using the first wireless communication network and for a second part of the field devices using the second wireless communication network.
