Abstract
Method for monitoring and controlling current distribution in load circuits of an installation control system of a technical installation, wherein a predetermined and constant output voltage is provided by a clocked power supply and distributed to the load circuits, where load circuits are protected by a switch actuated by a controller, a variation of the current in each load circuit is measured during a learning phase, a significant current profile with an associated tolerance range is derived and associated with the respective load circuit from the measured current variation which is continuously monitored by the control unit and a check is performed to determine whether a power capacity limit is reached by the clocked power supply while operate the installation, and the current consumed load circuits is reduced and/or switched off by actuating switches in load circuits in which a current variation exceeds an upper limit of the tolerance range.
