Abstract
A method for operating an automation system and an associated automation system in which all the error-free information is exchanged cyclically with a safety protocol, whereby information losses can thereby be recognized. Data that do not change even in the course of multiple transmissions are transmitted only once.
Claims18
Method for operating an automation system comprising an automation unit, at least one transmitter as an input unit connecting to at least one external sensor system, at least one receiver as an output unit connecting to at least one external actuator system, and a bus communicatively connecting the automation unit, the transmitter and the receiver;
- said method comprising:
- transmitting data via said bus by means of a telegram, said telegram having a variable part and a constant part;
- outputting the telegram at predefined or predefineable times;
- and
- transmitting the variable part without the constant part if the constant part is known both to the transmitter and to the receiver.
Automation system, comprising:
- an automation unit;
- at least one transmitter configured as an input unit connecting to at least one external sensor system;
- at least one receiver configured as an output unit connecting to at least one external actuator system;
- and
- a bus communicatively connecting said automation unit, said transmitter and said receiver;
- wherein:
- a data transmission via said bus is performed by means of a telegram;
- the telegram is output at predefined or predefineable times;
- the telegram has a variable part and a constant part;
- and
- the constant part is not transmitted together with the variable part if the constant part is known both to said transmitter and to said receiver.
