Abstract
There is a need for increasing the availability of data and/or control commands in a distributed control system for one or more machines, vehicles and/or processes. The control system comprises or is controlled by a transmitting node or transmitter unit and has two or more receiving nodes. The transmitting nodes and receiving nodes are connected to each other via wireless radio links. The receiving nodes are located at a distance from each other and are connected to a few-wire digital link in a wired system for forwarding of the said data and/or control commands to the executing devices. The control node transmits the said data and/or the control commands in different directions towards the receiving nodes which are arranged at a distance from each other. Receiving nodes with reception that is essentially not subject to interference are arranged to be able to connect to the few-wire link in parallel and simultaneously with a receiver unit or units which have links that are connected to the few-wire link. In another case, only those receiver unit or units are connected that have reception links that are not subject to interference, while the receiver unit of units with links that are subject to interference do not participate in the transmission of the message on the few-wire link.
