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 the devices. An inhibitor operates upon a device after it transmits data to inhibit access of that device to the communication link and to the indicator. A reset device is responsive to the indicator to remove the inhibitor when the indicator indicates that no data is to be transmitted.
