Abstract: The invention claims a process and device for ensuring the operational readiness of a battery in which the battery is first electrically connected with a testing device, and is then tested with the testing device to determine whether the battery is passivated. If the battery is passivated, a procedure for de-passivation of the battery is performed. If the battery is not passivated, a point in time for the next testing of the battery is scheduled.

Abstract: A method is for setting up temporary readiness of a field device for process automation to receive data in which a time interval is communicated to the field device during which it should be in transmit/receive mode. After expiry of this time interval, the field device switches back to a power-saving mode. As this time interval is freely selectable by a remote user, it is possible as a result to specify a suitable time for field device maintenance. As a result, it is possible to facilitate field device maintenance of battery-operated field devices which are in power-saving mode for the majority of the time.

Abstract: 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.
