Improved reliability through a function decentralized system. A • ¥»SOSP-> * x A ) *, 3* SUMK r SQUPTszttzv^-o ^wmm$<D mwz fi'ME£ it to In order to ensure higher reliability, a decentralized function system has been employed in our distribution systems for marine use. The decentralized function system has been designed to minimize the possible effects of any failure that might occur in a system by controlling four elements (safety, protection, automatic control, and manual control features) of the distribution system with completely independent units. For those independent units, the most reliable...

iTTITf^ Onboard multiple transmission network. Terasaki's multiple transmission system'TM", which has many records on uses, has been configured using loop It covers data transmission between the switchboard, group starter panel, and integrated type engine monitoring It is also applicable to communication with the bridge if serial transmission is used. This allows personnel in the bridge to very easily monitor the status of the power distribution system. Display unit 'T*fT^ Reduced maintenance cost. The modules of the PLC are independent for each func- tion. Therefore, if a failure occurs, it...
