Abstract
A monitoring system including a first and a second portion. The first portion includes a controller for receiving a code sequence. The first portion is configured to connect the system to a common data bus. The first portion is configured to provide a synchronization signal to the second portion when the two portions are in a predetermined position. The second portion includes a controller for providing the code sequence to the first portion and the first portion being further configured to output the code sequence for verification by a verification entity.
Claims18
A monitoring system comprising:
- a base part having a base controller, said base part connected to a common data bus;
- an interface part having an interface controller for receiving a synchronization pulse from said base part when said base part and said interface part are in a predetermined position;
- said interface controller receiving the synchronization pulse and providing a code set having a code sequence to said base part;
- and
- said base controller outputting said code sequence for verification by a verification entity.
A device for use in a safety controlling arrangement, said device comprising:
- a first transceiver;
- a microprocessor (MCU) connected to said first transceiver;
- and
- a bus driver connected to said MCU;
- said first transceiver adapted to communicate with a second transceiver by sending a synchronization pulse to the second transceiver, said MCU communicating with the bus driver by receiving a synchronization pulse from the bus driver and sending a code line to the bus driver;
- wherein when said device is in a predetermined position, said first transceiver sends the synchronization pulse to the second transceiver and said first transceiver receives a code sequence from the second transceiver for verification and/or transmission for further verification.
A safety device comprising:
- a second transceiver;
- and
- a microprocessor (MCU) connected to said second transceiver;
- said second transceiver adapted to communicate with a first transceiver by receiving a synchronization pulse from the first transceiver;
- and
- wherein when the device is in a predetermined position, said second transceiver receives the synchronization pulse from the first transceiver and second transceiver transmits the synchronization pulse to said MCU, and said MCU transmits a code sequence to said second transceiver for transmission to the first transceiver.
