Abstract:
A transceiver for wirelessly transmitting process variables with a radio interface and a field device interface is provided. The transceiver has two operating states. The transceiver is designed to receive a field device signal at the field device interface and relay the field device signal via the radio interface in the first operating state. In the second operating state, the transceiver receives a field device signal via the radio interface, and makes the field device signal available at the field device interface.
Abstract:
A field device acquires measured values and transferring data in an energy-controlled manner. A control device monitors the quantity of energy collected in the field device and triggers data transfer only when the quantity of energy collected has exceeded a predetermined threshold value. In particular, data transfer can take place at irregular intervals.
Abstract:
A communication module for a measuring instrument may include a first interface, a second interface, and an integrated web client. To the first interface a measuring instrument can be connected, whereas to the second interface a database can be connected. The communication module is configured to receive at the first interface a measurement value and to forward it to the second interface by the web client.
