app_weld_set_interface_eip_r2m_process

Definition
DRFLEx.h within class CDRFLEx, public section (line 1016)

bool app_weld_set_interface_eip_r2m_process(CONFIG_DIGITAL_WELDING_INTERFACE_PROCESS pConfigdigitalweldinginterfaceprocess)
{
    return _app_weld_set_interface_eip_r2m_process(_rbtCtrl, pConfigdigitalweldinginterfaceprocess);
};

Features

This function configures the EtherNet/IP communication interface for welders that support EtherNet/IP connectivity. It sets up interlocking signals between the robot controller and the welder, defining how communication data is transmitted from the robot controller → welder (R2M: Robot to Machine).

This command must be used when setting up EtherNet/IP-based welding systems, allowing synchronized control signals such as welding start, robot ready, and error reset to be sent to the welder. Refer to the communication datasheet of the specific welder model for valid signal ranges and mapping rules.

Note

To properly enable EtherNet/IP communication with a welding system, all eight related interface setup functions must be configured:

• app_weld_set_interface_eip_r2m_process ← (this page)

• app_weld_set_interface_eip_r2m_mode

• app_weld_set_interface_eip_r2m_test

• app_weld_set_interface_eip_r2m_condition

• app_weld_set_interface_eip_r2m_option

• app_weld_set_interface_eip_m2r_process2

• app_weld_set_interface_eip_m2r_monitoring

• app_weld_set_interface_eip_m2r_other

_nPositionalNumber	unsigned char	None	Data position index (1: 0, 0.1: 1, 0.01: 2)
_fMinData	float	None	Minimum data value
_fMaxData	float	None	Maximum data value
_nByteOffset	unsigned char	None	Communication byte location (1-255)
_nBitOffset	unsigned char	None	Communication bit location (1-255)
_nCommDataType	unsigned char	None	Communication data size 0: 1-bit(Disable Low) 1: 1-bit(Disable High) 2: 2-bit 3: 4-bit 4: 8-bit 5: 15-bit 6: 16-bit(short) 7: 32-bit(int)
_nMaxDigitSize	unsigned char	None	Effective bit length for communication data

Return

Value	Description
0	Error
1	Success

Example

CONFIG_DIGITAL_WELDING_INTERFACE_PROCESS processSetting;

// Welding Start Signal Mapping
processSetting._WeldingStart._bEnable      = 1;
processSetting._WeldingStart._bByteOffset  = 5;
processSetting._WeldingStart._bBitOffset   = 3;
processSetting._WeldingStart._bCommDataType = 4;  // 8-bit data

// Robot Ready Signal Mapping
processSetting._RobotReady._bEnable      = 1;
processSetting._RobotReady._bByteOffset  = 8;
processSetting._RobotReady._bBitOffset   = 0;
processSetting._RobotReady._bCommDataType = 4;

// Error Reset Signal Mapping
processSetting._ErrorReset._bEnable      = 1;
processSetting._ErrorReset._bByteOffset  = 10;
processSetting._ErrorReset._bBitOffset   = 2;
processSetting._ErrorReset._bCommDataType = 4;

// Apply configuration
bool result = Drfl.app_weld_set_interface_eip_r2m_process(processSetting);

This example maps the EtherNet/IP output channels for welding start, robot ready, and error reset signals. Each signal is assigned to a unique byte/bit position within the robot’s EtherNet/IP communication frame, allowing synchronized welding operations between the robot and the connected digital welder controller.
