Abstract (en)
[origin: WO0205241A1] With a field device (F), the operating device (B) is provided as a separately portable unit, which is connected by radio to the field device (S1) over short distances. This eliminates the need to directly locate an inaccessible field device (S1) for operation. In addition, several field devices (S1, S2, S3, A1, A2) can be operated by radio using an operating device (B). The local operation that, as a rule, is permanently integrated in the field devices (S1, S2, S3, A1, A2) can be disposed of.
