CONFIG_WELDING_INTERFACE

This structure defines the configuration for analog welding interfaces, including analog channel mappings (input/output) and digital I/O assignments for arc, gas, and wire feed control. It enables communication and control between the robot and external welding equipment.

BYTE#	Field Name	Data Type	Value	Remarks
0	_bEnable	unsigned char	0 or 1	Enable flag for the welding interface (0: Disabled, 1: Enabled)
1	_tChOut[2]	WELDING_CHANNEL		Output welding channels (0: Voltage channel, 1: Current channel)
37	_tChIn[2]	WELDING_CHANNEL		Input welding channels (0: Voltage channel, 1: Current channel)
73	_iArcOnDO	unsigned char	0~15	Digital output channel for Arc On signal
74	_iGasOnDO	unsigned char	0~15	Digital output channel for Gas On signal
75	_iInchPDO	unsigned char	0~15	Digital output channel for Inching + signal
76	_iInchNDO	unsigned char	0~15	Digital output channel for Inching - signal

Note

• WELDING_CHANNEL defines the analog I/O configuration for individual channels.

• CONFIG_WELDING_INTERFACE groups all analog and digital parameters for full welding control.

• Typical wiring:
  - Arc On / Gas On → Digital outputs
  - Voltage / Current feedback → Analog inputs
  - Voltage / Current control → Analog outputs
  

• Used for MIG/TIG welding integration in Doosan robot systems.
