Deterministic access protocol local area network.

摘要

A data controller to control passage of data between a plurality of data handling devices comprises a communication link to permit communication of the devices with one another. An indicator is associated with each of the devices to indicate data is to be transmitted from any one of said devices. Inhibit means operate upon a device after it transmits data to inhibit access of that device to the communication link and to the indicator. Reset means are responsive to the indicator to remove the inhibit means when the indictor means indicates that no data is to be transmitted.
