Power control network for multiple digital modules
First Claim
1. In a system of interconnected modules which include at least one processer module, at least one I/O module, and at least one memory module, and wherein each module includes internal power control switching means and internal power supply means, a power control network for controlling an on/off power status or condition of any selected module, said power control network comprising:
- (a) master logic power unit means for sensing the power status of each of said modules and for transmitting control instructions for regulating the on/off power status of a selected module, or modules, or all of said modules; and
(b) slave logic power unit means for receiving said control instructions and for regulating the power status of each of said modules, said slave logic power unit means including;
(b1) a plurality of slave logic units each of which is connected to said master logic unit means and wherein each of said modules is provided with an individual slave unit residing therein, each of said slave logic units including;
(b1a) means to sense the power status of the said internal power supply means residing in the same module as the said slave logic unit;
(b2) said power control switching means operating under control instructions from said master unit, via said slave unit, for switching the power on or off in the module in which said slave unit resides, and wherein said power control switching means includes;
(b2a) means to cause said internal power supply means to have its output increased or decreased by a fixed percent amount.

Abstract
A power network control system has a plurality of digital modules interconnected. A master logic unit in the network communicates with a specialized protocol to slave logic units in each module. The slave logic unit can instruct a power control circuit to turn-off or turn-on various power supply modules in addition to adjusting a power module in steps of plus or minus fixed percentage amounts.
