Abstract
A method for operating an automation system with a plurality of communication users linked for communication purposes via a serial connection, of which at least one functions as sender and at least one as a receiver, includes determining at a sender an offset value between an occurrence of a synchronous signal and a communication clock cycle, transmitting the determined offset value in a data transmission to the at least one receiver, waiting at the at least one receiver until a time period commensurate with the offset value has elapsed, and generating at the at least one receiver an output signal after the time period has elapsed.
Claims12
A method for operating an automation system with a plurality of communication users linked via a serial connection for communication, with at least one communication user operating as a sender and at least one communication user operating as a receiver, comprising the steps of:
- determining at the at least one sender an offset value between an occurrence of a synchronous signal and a communication clock cycle,
- transmitting the determined offset value in a data transmission to the at least one receiver,
- waiting at the at least one receiver until a time period commensurate with the offset value has elapsed, and
- generating at the at least one receiver an output signal after the time period has elapsed.
A computer program having program code instructions stored on a non-transitory medium, wherein the program code instructions, when loaded into a memory of a processing unit of an automation device having a plurality of communication users linked for communication purposes via a serial connection, of which at least one functions as sender and at least one as a receiver, and executed by the processing unit, cause the automation system to:
- determine at the at least one sender an offset value between an occurrence of a synchronous signal and a communication clock cycle,
- transmit the determined offset value in a data transmission to the at least one receiver,
- wait at the at least one receiver until a time period commensurate with the offset value has elapsed, and
- generate at the at least one receiver an output signal after the time period has elapsed.
An automation device with a plurality of communication users linked for communication purposes via a serial connection, of which at least one functions as sender and at least one as a receiver, the automation device comprising a processing unit and a memory, with a computer program having program code instructions being loaded into the memory from a non-transitory medium and executed by the processing unit, causing the automation system to:
- determine at the at least one sender an offset value between an occurrence of a synchronous signal and a communication clock cycle,
- transmit the determined offset value in a data transmission to the at least one receiver,
- wait at the at least one receiver until a time period commensurate with the offset value has elapsed, and
- generate at the at least one receiver an output signal after the time period has elapsed.
