Problems solved by technology

This aspect is particularly relevant for so-called pressure-resistant explosion-proof devices, since in the pressure-resistant housing the connection of switches / buttons for the user interface leads to high costs, for which reason only a few operating switches are available in many cases

Embodiment Construction

[0059] First, facility A can be tested using the method according to the invention. Picture 8 An overview of related personnel and equipment is given. The facility A includes at least one first unit M and at least one second unit FD as its main components. It will first be expanded on the second unit FD.

[0060] See the second unit, in this example, field devices (FD) in process automation technology, such as sensors. more specifically, figure 1 Two field devices FD1 and FD2 are shown that are both "second unit FD" type devices. The terms "field device" and "second unit" are used synonymously in the following. The field device FD is especially a field device of two-wire technology. The field device FD has a fairly "simple" design in terms of operation; in particular, the field device should only have basic options for input and output. The field device has, for example, only a few buttons and switches and no display, or only a "simple" one, that is, a two-color display show...

Abstract

The invention relates to a method for the authentication of at least one first unit on at least one second unit. Through communication circuits preperably as wireless communication lines between first units especially on-site equipment and second unit especially mobile equipments, in a facility especially in a field of a process automation technology, the first units are authenticated on the second units on a single aspect or in a mutual manner. The method comprises the steps of: establishing a security policy including rules for granting access of the first unit on the basis of at least one unlock key, and information to check the unlock key for validity; providing the security policy to the second unit; generating an unlock key for the first unit and providing the unlock key at the first unit; transferring the unlock key from the first unit to the second unit and verifying the unlock key by the second unit using the security policy and, if applicable, granting access. Furthermore, a computer program product executes the method and a machine-readable data carrier includes the computer program product.

Description

Technical field [0001] The invention relates to a communication line, especially a wireless communication line between at least one first unit, especially a mobile device, and at least one second unit, especially a field device, in a system, especially in the field of process automation technology. Communication line, the method of authenticating the first unit on the second unit. The invention further relates to a computer program product for executing the method and a machine-readable data carrier including the computer program product. Background technique [0002] Field devices used to capture and / or adjust process variables are frequently used in process automation technology. Field devices usually refer to all devices that are process-oriented and provide or process process-related information. In addition to sensors and actuators, the units directly connected to the fieldbus are also generally called field devices, which are used to communicate with upper units, such as ...
