Claim 7:
8. A method for a control device having a dedicated hierarchy level to obtain DC current from a power source on the control network the method comprising:
sending over the control network a first query to the power source regarding an amount of available current of the power source;
receiving over the control network a reply from the power source about the amount of available current;
determining if the amount of available current of the power source is sufficient as compared to a required supply current of the control device;
sending a command over the control network to a second control device having a dedicated hierarchy level lower than the control device, instructing the second control device to send a release request to the power source to release supply current allocated to the second control device, when the amount of available current of the power source is determined insufficient; and
sending a current request over the control network to the power source for the required supply current, when the amount of available current of the power source is determined sufficient or after confirming the command is executed by the second control device.
