Abstract
To provide a method for configuring a field device, and a corresponding parameterization system, that enables secure transfer of parameter values via a potentially unsafe data link the method establishes a data link (3) between the field device and a parameterization unit, a parameterization value is transmitted by the parameterization unit to the field device, a parameterization value is received by the field device. Furthermore, a first test value is generated by the parameterization unit from the parameterization value, a second test value is generated by the field device from the received parameterization value. Then, the test values are compared to one another.

Method for configuring a field device, comprising the steps of:
- establishing at least one data connection between a field device and a parameterization unit,
- transmitting at least one parameterization value by the parameterization unit to the field device
- receiving the at least one parameterization value by the field device,
- generating at least one first test value by the parameterization unit at least from the at least one parameterization value to be transmitted,
- generating at least a second test value by the field device at least from the at least one received parameterization value, and
- comparing at least the first test value to the second test value and generating a comparison result therefrom.
System for configuring a field device, comprising:
- a parameterization unit, and
- at least one data connection between a field device and the parameterization unit,
- wherein the parameterization unit is adapted to transmit at least one parameterization value to the field device which is adapted for receiving the at least one parameterization value,
- wherein the parameterization unit is also adapted for generating at least one first test value from the at least one parameterization value,
- wherein the field device is adapted for generating at least a second test value at least from the at least one parameterization value, and
- means for comparing at least the first test value to the second test value and generating a comparison result therefrom.
