摘要:
A method for generating a device description for a measuring apparatus in a target field bus protocol is described. The method comprises the reception of a first device description of the apparatus. The first device description of the apparatus comprises at least one variable. The at least one variable is related to a storage cell of the apparatus. The target field bus protocol is selected from a plurality of field bus protocols, and at least one block is formed from the at least one variable. The at least one block has a maximum block size that corresponds to the smallest maximum block size of at least two field bus protocols of the plurality of field bus protocols. The maximum block size can be transmitted via a field bus with a single request when the respective field bus protocol is used. Subsequently, the at least one block is provided as device description for the apparatus in the target field bus protocol.

摘要:
This invention relates to a data transmission system for wireless communication of a control device with a field unit via a radio transmission device. The communication between control device and radio transmission device takes place via a field bus protocol. Likewise, the communication of the field unit with the radio transmission device takes place via a field bus protocol. The radio transmission device is capable of transmitting the field bus protocol by a radio protocol.

摘要:
An image with text in a selected language for use in a multilingual operating program for a fill-level measuring device or a pressure measuring device is generated in that a text-free image is overlaid with the corresponding text modules in the selected language. This does not require changing the image. The overlay is controlled by means of a control file.
摘要:
Described is a method for determining a telegram length in an operating apparatus for communicating between the operating apparatus and a field device via a network. The method comprises composing a first telegram in the operating apparatus. The first telegram comprises a predeterminable first telegram length, and the composed first telegram is despatched via the network to the field device. After the first telegram has been despatched, the operating apparatus waits for the receipt of a second telegram, which second telegram is received by the operating apparatus via the network. After successful receipt of the second telegram, the first telegram length is increased by a predeterminable value. Increasing the value takes place until receiving the second telegram fails. After the receipt of the second telegram has failed, the first telegram length that has resulted in successfully receiving the second telegram is provided.
