Patent attributes
A measurement or protective device has a terminal for establishing a connection to a data bus. A control device determine the mode of operation of the measurement or protective device, and the mode of operation can be changed from the outside using the terminal. The novel device enables evaluation operations, in particular testing operations, from the outside in an even simpler manner than before. The control device is configured in such a manner that it can operate at least two software modules in parallel and independently of one another. One of the software modules is an operating module which determines the measurement or protective mode of operation of the device, and at least one additional software module has another function. The control device has at least one software interface to which the additional software module can be coupled, in terms of software, from the outside using the terminal.
