<p><P>PROBLEM TO BE SOLVED: To provide the configuration of an I/O communication network that provides bus power, so that separate power supply devices are connected to the bus, in addition to a bus controller and field devices connected to the bus, to be able to provide power on the bus. <P>SOLUTION: An integrated bus controller and power supply device 72 includes a bus controller 80 and a bus power supply 82 arranged within a common housing 86 that can be matched in the size and external configuration to the standard bus controller device related to the ordinary I/O communication network, and stores and executes one or more control routines using one or more field devices connected to the I/O communication network. On the other hand, the bus power supply generates an appropriate power signal and supplies this power signal to the bus of the I/O communication network. This power signal is used for power supply to the field device. The integrated bus controller and power supply device can be easily connected to the bus of the I/O communication network to provide both bus controller functionality and bus power supply functionality therefor. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
