Method for operating a system of modular structure, in particular a process automation system
First Claim
1. A method for operating a system of modular structure, which is extendable during operation by adding modules consuming electrical energy, comprising:
- providing a power supply for the system, wherein the power supply supplies the modules of the system consuming electrical energy with electrical energy;
generating a signal fora remaining residual power for a further module to be added, wherein the signal is generated before the further module consuming electrical energy is added to the system, ora level of power, which the power supply supplies currently to already added modules, oridentifying or deriving whether the further module to be added can be added without overloading the power supply; and
displaying the signal;
wherein a computation and control facility assigned to the system determines or takes from a storage unit a maximum number of addable modules respectively for different classes of modules of different power consumption values, the maximum number of addable modules being the number of addable modules which can be added without a predefined overload power limit value being reached or exceeded, anda class-dependent, maximum number is determined from upper power consumption limit values assigned to each class, which respectively form an upper limit for all addable modules of each corresponding class, and from a current value of a residual power of the power supply provided to the already added modules.

Abstract
There is described a method for operating a system of modular structure, which can be extended during operation by adding modules that consume electrical energy, in particular a process automation system, the system having a power supply, which supplies the other modules of the system with electrical energy, with at least one signal being generated and displayed before a further module that consumes electrical energy is added, from which signal it is possible to identify or derive the level of current electrical power, which the power supply can still supply to the further module to be added given the already added modules—residual power—and/or the level of power, which the power supply supplies currently to the already added modules and/or from which it can be identified or derived whether the module to be added can be added without overloading the power supply.
