A system provides data communications between measurement data generating/receiving modules connected to a common communication bus. A master station connected to the communication bus can assign access priority to various message data structures generated by each of the modules connected to the communications bus. As modules are added or subtracted from the total system, the master station can reassign priorities to each of the message data structures generated by the modules. In this way, bus traffic can be efficiently controlled with the ability to dynamically change priority of message data structures which are sent over the bus by the various modules. A transmission delay time is also assigned to each of the message data structures which requires that a time out period following the last data message to be sent over the bus be observed before transmitting the new message data structure. The different delays VT are related to the particular priority of a message data structure. |
