<p>PROBLEM TO BE SOLVED: To provide an information transmission device for railway vehicle which reduces the number of transmission path systems laid across vehicles and increases the degree of freedom of data exchange between a control transmission system and a monitor transmission system.SOLUTION: An information transmission device for railway vehicle to which the industrial Ethernet (R) PROFINET IO is applied performs data exchange between an IO controller and each IO device by: performing address solution processing of the IO device when starting up a system; and sequentially transmitting data frames by the IO controller and each IO device according to a preset refresh period, after the procedure of establishment of connection between the IO controller and each IO device, the IO controller's setting a parameter to each IO device, and application preparation completion notification from each IO device, and the like.</p> |
