Problems solved by technology

[0004] At the same time, even if the generally well-known device net shown in Fig. 2 is used as an example of a field bus communication device, there are problems such as the length of each connecting wire becoming long and the need to use a tap 33, thereby requiring a separate installation of the general I / O O interface slave device 35, which has just resulted in inefficient use of equipment as a whole, because the length between PLC 32 and welding controller 34, and the length between PLC 32 and general I / O interface slave device 35 are respectively in Space separated by a long distance

Abstract

A welding system capable of shortening length of connection lines and the of effectively utilizing devices as a whole. The system comprises a welding controller (3) provided with an I / O interface (6), a controller (1) provided with a programmable logic (2) and connected to the I / O interface (6) of the welding controller (3) through a field bus interface (7) serving as communication means, a welding machine (4) and a general-purpose peripheral equipment (5), wherein the welding controller (3) controls the welding machine (4) and the general-purpose peripheral equipment (5) upon receipt of instructions from the programmable logic controller (2) through the field bus interface (7).

Description

technical field [0001] The invention relates to a welding system including a welding controller. Through a network, the welding controller can operate according to instructions issued by a controller equipped with a PLC (Programmable Logic controller). Background technique [0002] Generally, welding machines and general Peripherals are controlled by arranging multi-strand wires, that is, by connection of multi-strand wires used between controllers equipped with PLCs and the like and welding controllers, general-purpose peripherals. In this case, since the device needs to be connected by multi-strand wires to output control commands, it is very complicated in terms of information or command transmission and the composition of the command device. [0003] Therefore, it is considered to use the well-known field bus as a communication device to realize the command transmission from the controller equipped with PLC to the welding controller and general peripheral equipment (gen...
