<P>PROBLEM TO BE SOLVED: To provide a power supply system which can appropriately cope with disconnection of a power supply bus. <P>SOLUTION: A disconnection detecting means 101 detects disconnection of the power supply bus. When the disconnection detecting means 101 detects disconnection, a connection means 102 connects both ends of the power supply bus. A first power supply means 104A is connected to one end-side of the power supply bus and is connected to a field unit through the power supply bus. A second power supply means 104B is connected to the other end-side of the power supply bus and is connected to the field unit through the power supply bus. A disconnection detecting means 105 detects disconnection of a communication bus. When the disconnection detecting means 105 detects disconnection, a control means 106 functions the first power supply means 104A and the second power supply means 104B. <P>COPYRIGHT: (C)2007,JPO&INPIT |
