Abstract
A circuit arrangement for transmitting data between a field unit and a control device with a first data interface for being coupled to the control device and a second data interface for being coupled to the field unit. A galvanic isolator is situated between the data interface on the side of the control device and the data interface on the side of the field unit, wherein the first data interface and the second data interface are coupled in a communicating fashion by the galvanic isolator. The circuit arrangement furthermore features at least one data storage device, wherein the data storage device is either coupled to the first data interface or the second data interface. The data storage device is designed in such a way that data of at least the first or the second data interface can be recorded on demand by the data storage device.
