Abstract
Disclosed is a method for starting up of at least one first field instrument, wherein the method comprises the step of signaling a firs demand for electrical power output of the first field instrument over a first port to a supply unit. According to this method, the first field instrument is previously connected to the supply unit over the first port by means of a first communication connection. In addition, the reception of the power output is effected according to the first demand for power output by the first field instrument over the first communication connection and the first port, by which the first filed instrument is activated. In an additional step, a power usage unit of the first field instrument is assigned to the first port, wherein the power usage unit is provided as consumer load for the power output.

28. A method for starting up a first field device, comprising:
-
signaling a first electrical power requirement of the first field device via a first port to a supply unit, the first field device having been previously connected to the supply unit via the first port by a first communication connection; taking up the power according to the first power requirement by the first field device via the first communication connection and the first port, resulting in the first field device being activated; allocating a power drawing unit of the first field device to the first port, the power drawing unit provided as a consumer for the taken up power; and allocating a power supply unit of the first field device to a second port, the power supply unit provided to supply a second power requirement via the second port. - View Dependent Claims (29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39)

47. A computer program product having a computer-executable instructions for a supply unit to start up at least one first field device, the computer program product containing computer-executable instructions for execution on a computer device, comprising:
-
receiving a first message from the field device via a communication connection, the first message containing information about the power requirement of the field device; detecting whether the power requirement is suppliable by the supply unit; transmitting a second message to the field device via the communication connection, the second message containing information about whether the power requirement is suppliable; and supplying the power requirement for the field device via the communication connection.
