Patent number: 9750083Abstract: A method for communication between a wireless device node in a wireless sensor network and control apparatus or control processes of an industrial control system. The wireless network includes a plurality of device nodes and at least one gateway. The method includes receiving at a gateway an aggregated data packet or a final address in the ICS. The gateway processes the data packet, detects that it is an aggregated data packet and reconstructs the original data packets contained therein. The gateway then sends each of the original data packets as standard data packets to the intended final address in the ICS. In other aspects of the invention a method, system and a computer program for carrying out the method are described.Type: GrantFiled: December 4, 2012Date of Patent: August 29, 2017Assignee: ABB Research Ltd.Inventors: Mikael Gidlund, Tomas Lennvall, Jonas Neander

Patent number: 9451498Abstract: A method for communication in a wireless sensor network of an industrial control system. The network includes a plurality of device nodes and at least one gateway. The method includes aggregating in at least one wireless device data originating from at least two data packets. The method includes receiving at a first node at least one first data packet for a first destination address and aggregating data from the at least one data packet with data from at least one second data packet, intended for the same first destination address, forming an aggregated data packet and sending the aggregated data packet to another node or to said gateway. In other aspects of the invention a method, system and a computer program for carrying out the method are described.Type: GrantFiled: September 14, 2012Date of Patent: September 20, 2016Assignee: ABB Research Ltd.Inventors: Mikael Gidlund, Tomas Lennvall, Jonas Neander

Patent number: 9451468Abstract: 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.Type: GrantFiled: June 23, 2011Date of Patent: September 20, 2016Assignee: ABB Research Ltd.Inventors: Tomas Lennvall, Tiberiu Seceleanu

Patent number: 9198061Abstract: 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.Type: GrantFiled: April 25, 2013Date of Patent: November 24, 2015Assignee: ABB Research Ltd.Inventors: Tiberiu Seceleanu, Tomas Lennvall
