Abstract
A monitoring system including a first and a second portion. The first portion includes a controller for providing a set of codes. The first portion is configured to connect the system to a common data bus. The first portion is configured to provide a synchronisation signal to the second portion when the two portions are in a predetermined position. The second portion includes a controller for replaying a code sequence to the first portion and the first portion being further configured to output said code sequence from the second portion for verification by a verification entity.
Claims16
A monitoring system comprising a first and a second portion, said first portion being configured to connect said system to a common data bus, characterised in the said first portion is configured to provide a synchronisation signal to said second portion, when the two portions are in a predetermined position, said second portion comprising a controller for replaying a code sequence to said first portion and said first portion being further configured to output said code sequence from said second portion for verification by a verification entity.
A device for use in a safety controlling arrangement, said device comprising a transceiver, a micro-processor, MCU, and a bus driver, said transceiver and MCU being connected and communicate by a transceiver by sending a synchronization signal, said MCU communicating with the bus driver by sending a synchronization signal and receiving a code line, characterized in that said device is configured to receive a synchronization signal when in a predetermined position and transmit said synchronization signal by means of said transceiver and receiving a code sequence by said transceiver for verification and/or transmission for further verification.
A safety device comprising a transceiver and a micro-processor, MCU, said transceiver and MCU being connected and communicate by transceiver sending a synchronization signal and MCU replying with a code sequence characterized in that said MCU is further configured to upon reception of said synchronization signal in a predetermined position, to generate said code sequence and provide it to the transceiver for transmission.
