PROBLEM TO BE SOLVED: To solve problem that a conventional electric apparatus inputs/outputs information from/to an external at a special input/output circuit, an input/output function is not flexible, and it is necessary to add and change a circuit in response to a functional change of the electric apparatus.SOLUTION: An input/output device having an input/output function of information to/from an external apparatus includes: an input circuit for inputting information from the external apparatus; an output circuit for outputting information to the external apparatus; and a control part which communicates with the input circuit, the output circuit, an electric apparatus, and an external control apparatus. The electric apparatus communicating with the input device includes: a storage part which stores which port of the input circuit an input from the external apparatus is allocated and which port of the output circuit an output is allocated; and a welding device input/output control part which sends information indicating that a function of the electric apparatus is operated by information from the control part or that which port of the output circuit the output from the electric apparatus is output. Information related to allocation is stored in the storage part or the information related to the allocation stored in the storage part is changed by using the external control device. |
