Apparatus for supplying power to a field device, comprising: a first electrical connector adapted to electrically couple a field device to the apparatus, a power supply unit electrically coupled to the first connector and adapted to provide electrical power to a field device via the first connector; a local user input, e.g. a manually operated switch, adapted to be actuated by a user; a monitoring circuitry electrically coupled to the local user input and adapted to detect an actuation of the local user input. The monitoring circuit is adapted to generate an activation signal causing the power supply unit to provide electrical voltage to the first electrical connector for powering a field device electrically coupled to the first connector.

Apparatus for supplying power to a field device

An electrical and/or electronic supply circuit, which serves to provide a first or a second, essentially constant value of a supply voltage, which supply voltage serves to operate an operating electronics. The supply circuit serves to output the first value of the supply voltage when the supply voltage is derived from a first voltage source, and the supply circuit serves to output the second value of the supply voltage when the supply voltage is derived from a second voltage source.

Electrical and/or electronic supply circuit and method for providing a supply voltage

In connection with a method for the data exchange between an operating and monitoring program BA and a field device, which is connected via a field bus adapter with the internet, the operating and monitoring program BA accesses a serial interface, which is connected with an internet interface. By means of this a data exchange between the operating and monitoring program BA via the internet is possible without extensive program changes.
