Abstract
An error diagnosis circuit includes a signal input for connection to a communication interface, configured to receive a first instruction and a second instruction for a device. A circuit is configured to compare the first instruction and the second instruction and to output an error signal if the first instruction and the second instruction differ from one another.
Claims20
An error diagnosis circuit, comprising:
- a signal input component, for connection to a communication interface, configured to receive a first instruction, comprising a first address associated with a device, and a second instruction, comprising the first address associated with the device;
- and
- a circuit, within the error diagnosis circuit, comprising:
- a first flip-flop component configured to store the first instruction,
- a second flip-flop component configured to store the second instruction, and
- an exclusive OR gate configured to:
- compare the first instruction and the second instruction, and
- output an error signal when the first instruction is different from the second instruction,
- wherein the error diagnosis circuit is used only to detect an error associated with the error signal.
6 more elements
A method, comprising:
- receiving, by a first flip-flop component of an error diagnostic circuit and from a data bus, a first instruction, comprising a first address;
- receiving, by a second flip-flop component of the error diagnostic circuit and from the data bus, a second instruction comprising the first address;
- transmitting, by the first flip-flop component to an exclusive OR gate of the error diagnostic circuit, the first instruction;
- transmitting, by the second flip-flop component to the exclusive OR gate, the second instruction;
- comparing, by the exclusive OR gate, the first instruction and the second instruction;
- and
- outputting, by the exclusive OR gate, an error signal, when the first instruction is different from the second instruction, or the first instruction or second instruction, when the first instruction is identical to the second instruction,
- wherein the error diagnosis circuit is used only to detect an error associated with the error signal.
5 more elements
A circuit, comprising:
- a first flip-flop component configured to receive a first instruction comprising a first address associated with an actuator;
- a second flip-flop component configured to:
- receive the first instruction and a second instruction, wherein the second instruction comprises a second address associated with the actuator,
- output the first instruction;
- and
- an exclusive OR gate configured to:
- receive, from the first flip-flop component, the first instruction,
- receive, from the second flip-flop component, the second instruction,
- compare the first instruction and the second instruction, and
- output a signal based on whether the first instruction is identical to the second instruction.
