Abstract

PROBLEM TO BE SOLVED: To reduce the connection of personal computers or the like by storing picture data sent to its own station in a storage device and transferring picture data which are not data transmitted to the station itself to another station specified by a prescribed message through a network. SOLUTION: At the time of receiving picture data from a personal computer 2, a system management function 23 recognizes whether the data from the computer 2 are sent to its own station or not based on a station number specified by a picture data message, and when the data are sent to the station itself, stops a monitor function 21 and programmable controller(PC) reading function 22 in order to store the data from the computer 2 and stores the picture data in a storage device. When the data are not sent to its own station, a transfer means 24 transfers the picture data received from the function 23 to a PC communication function 25, which transmits the data to a PC 3 corresponding to a station number to be transferred through another PC 3 connected to the function 25 by using transit transmission or the like.
