is sent back from the matrix 50 to the soft controller 30 through the control channel gateway 40 tenth in addition this information is sent back to the ips dp 20 through a division gateway eleventh the ips dp 20 then sends the feedback information to then information flat panel display acting as a part of the ips dp 20 thereby the operator can cross check this information using the plant information display or the soft controller 30 in the introduction to this specification the requirements were discussed that a nuclear power plant control conform to the requirements of idd 603 1991 and ieee 7 4 3 2 and be defensible for licensing the advantages of the system according to the invention with respect to these requirements will now be discussed as previously noted in order to meet the requirements of these sections it is necessary to incorporate some method that would provide functional isolation to maintain the independence of the safety and non safety equipment and prevent the non safety equipment from impacting the safety function functional isolation among the elements or nodes attached through the soft control network 20 30 is established by the coding and encryption method employed to the data transmitted each of a plurality of control channels is the receiver of the encrypted data on the soft control network via the control channel gateways 40 the notion that a plurality of control channels can be used with a corresponding or lesser number of control channel gateways is later discussed with respect to fig4 moreover as to support for the isolation functionality noted immediately above each of the control channel gateways.
