Input/output client server system for transmitting commands to general purpose input/output by using IP address, interface address, and physical port address

摘要

An input/output client/server system within a remote control system between general purpose apparatuses provided with TCP/IP compliant communications functions across networks comprising: single or plural general purpose input/output units mounted on the interface boards of remote input/output devices of a general purpose apparatus on the receiver side and provided with a function to give a predetermined response to a command transmitted thereto from a general purpose apparatus on the transmitter side; means for recognizing addresses of the general purpose input/output units provided on the general purpose apparatus on the receiver side; and means for transmitting a command to the general purpose input/output unit by using an IP address of the general purpose apparatus at the destination, an address of the respective interface connected to the respective general purpose input output unit, and the port address of the general purpose input/output unit connected to the general purpose apparatus on the transmitter side.
