Abstract
In a method for parametering a field device of process automation technology, wherein the field device is connected via a bus system with a control unit, parameter values are packaged in telegrams of cyclic services and transmitted to the field device whose parameter values are to be changed. No acyclic services are required for changing parameter values.

A method for parametering a field device of process automation technology, wherein the field device is connected with a control unit via a bus system and exchanges telegrams with the control unit in cyclic data traffic, the cyclic data traffic serves for reading or writing process data in the field device without address specification, the method comprising the steps of:
- packaging address value and associated parameter value into at least one telegram of a cyclic service in the control unit;
- transmitting the one or more telegram(s) to the field device;
- ascertaining the address value and the associated parameter value from the one or more telegram(s) received in the field device;
- and
- writing the parameter value to a memory address specified by the address value in the field device.
