Abstract: The disclosure relates to a recording device for visualizing measured values and parameters of field devices in automation devices, having at least one analogue input for directly connecting at least one wired field device and having an Ethernet interface for communicating with a superordinate device. A graphical display is provided for indications and an exchangeable storage unit is provided for retrospectively recording measured values and parameters of field devices. In order to communicatively acquire wired and wireless measured value acquisition processes, a wireless communication interface having a signal converter which is connected to the Ethernet interface is included.
