Abstract: A field device having a safe interface is based on two voltage regulators designed to set electrical current between corresponding contacts of the interface. The field device tests via which of the contacts the field device is connected with a superordinate unit and an automatic configuration of the interface can be performed for the appropriate transmission standard. Because the contacting to the superordinated unit is checked repetitively by means of two electrical current regulators it is assured that the field device can determine and automatically react to a change of the contacting at the interface even during measurement operation. This makes the interface safe and thereby increases the safety of the process plant, in which the field device is applied.
