Abstract
The invention relates to a method for setting consistent values for a parameter in a network of distributed stations (10 to 14), and to a corresponding network subscriber station.In certain circumstances, it has been found that inconsistent entries can occur for the gap count parameter on the local bus in an IEEE 1394 network. If the bus management instance (25, 26) relies on the automatic behavior, as provided in the Standard, of all the network subscriber stations (10 to 11) to automatically set the maximum value of 63 after the second bus resetting process without any intermediate resetting of this parameter, this can lead to progressive resetting of the network, and this can result in blocking of the network.The problem is solved by immediate transmission of a parameter setting message for the critical network parameter once an inconsistency has been found. Alternatively, two or more successive inconsistency findings will be tolerated, with the parameter setting message not being transmitted until this stage.
