Abstract
A data bus subscriber connected to a local bus, particularly a ring bus, has a status signal input for receiving a first status signal value from a downstream data bus subscriber or a terminator, and a status signal output for providing a second status signal value to an upstream data bus subscriber or to a local bus master. The data bus subscriber is adapted to provide the second status signal value based on a logical link of a communication readiness of the data bus subscriber and the first status signal value.
Claims18
A bus system, the bus system comprising:
- a first data bus subscriber;
- a second data bus subscriber;
- a first hardware base element;
- a second base element, the first hardware base element and the second hardware base element forming a communication infrastructure for the bus system;
- a first processor in the first data bus subscriber;
- a second processor in the second data bus subscriber;
- and
- two switches configured to control bus communication to the first processor and the second processor,
- wherein the first data bus subscriber and the second data bus subscriber are configured to connect to a respective one of the first hardware base element and the second hardware base element, and
- wherein the communication infrastructure between the first hardware base element and the second hardware base element includes an uplink and a downlink.
A bus system, the bus system comprising:
- a first data bus subscriber;
- a second data bus subscriber;
- a first hardware base element;
- a second base element, the first hardware base element and the second hardware base element forming a communication infrastructure for the bus system;
- a first processor in the first data bus subscriber;
- a second processor in the second data bus subscriber;
- and
- two switches configured to control a bypass of one or more of the first data bus subscriber and the second data bus subscriber,
- wherein the first data bus subscriber and the second data bus subscriber are configured to connect to a respective one of the first hardware base element and the second hardware base element, and
- wherein the communication infrastructure between the first hardware base element and the second hardware base element includes an uplink and a downlink.
A bus system, the bus system comprising:
- a first data bus subscriber;
- a second data bus subscriber;
- a first hardware base element;
- and
- a second base element, the first hardware base element and the second hardware base element forming a communication infrastructure for the bus system,
- wherein the first data bus subscriber and the second data bus subscriber are configured to connect to a respective one of the first hardware base element and the second hardware base element,
- wherein the communication infrastructure between the first hardware base element and the second hardware base element includes an uplink and a downlink, and
- wherein the first data bus subscriber and the second data bus subscriber each have a first interface and a second interface forming the downlink and each have a third interface and a fourth interface forming the uplink.
