A method for providing safe access of a mobile control unit () to a field device (), wherein, in particular, the field device is protected against unauthorized access via a mobile control unit is achieved in that a connection for transmitting data is established between the mobile control unit () and the field device (), that access data for access is exchanged, that a comparison is made between the access data and stored comparison data and a comparison result is generated, and that access of the mobile control unit () to the field device () is permitted based on the comparison result.

Method for safe access to a field device

A communication arrangement, a gate device and method for data communication between a mobile operating unit and a field device provides a certain ease in handling. The method involves a user program being loaded onto or activated on the mobile operating unit. Furthermore, data from the mobile operating unit is transmitted to a data communication device and from the data communication device to a gate device and from the gate device to a transmitting device of the field device and/or is transmitted in the opposite direction.
