Abstract
The invention relates to a method for quasi-continuous transmission of a temporally variable parameter between a transmitter and a receiver. In order to provide the time characteristic of the parameter for initiating an operationally related function, said characteristic is determined at least approximately on the basis of the transmitted information in a processing device connected downstream of the receiver.
Claims17
A method for providing quasi-continuous transmission of a temporally variable parameter to initiate an operationally related function in a control and data transmission system, comprising the following steps:
- transmitting at least one element of information at discrete time intervals via a transmission medium to a receiver, and
- determining a time characteristic of the temporarily variable parameter at least approximately in a processing device connected downstream of the receiver, by taking account of the at least one information element,
- the transmitted information being a discrete value of the temporally variable parameter and the time characteristic being determined at least approximately by taking account of at least two transmitted discrete values of the temporarily variable parameter.
