Portable mass storage device, method for carrying out a data transfer between a host system and a field device and use of the portable mass storage device

摘要

A portable mass storage device (1) comprising a first interface for data connection to a host system (11), characterized in that the mass storage device (1) has a second interface, which is an electromechanical plug-in system (4) for connection to a field device (14), The mass storage device has a voltage source (8) for supplying energy to the mass storage device (1) in a first communication mode, the portable mass storage device having a computing and / or control unit (20) which is designed to carry out at least the first communication mode, in which a data transfer takes place between the portable mass storage device (1) and a field device (14) connected to it, as well as a method for managing a data transfer between a host system (11) and a field device (14) and three uses of the portable mass storage device.
