bool app_weld_set_interface_eip_r2m_condition(CONFIG_DIGITAL_WELDING_INTERFACE_CONDITION pConfigdigitalweldinginterfacecondition)

    return _app_weld_set_interface_eip_r2m_condition(_rbtCtrl, pConfigdigitalweldinginterfacecondition);
};

Features

This function configures the EtherNet/IP communication interface for welding systems that support EtherNet/IP connectivity. It defines the mapping of welding condition control signals—such as parameter adjustment, correction enablement, and condition synchronization—sent from the robot controller → welder.

This setup allows the welder to receive welding condition settings in real time (e.g., voltage correction, current correction, or synergic adjustments). Refer to the communication datasheet of the connected welding device for compatible condition parameters.

Note

To fully utilize EtherNet/IP-based welding functionality, all 8 related interface configuration commands must be set:

• app_weld_set_interface_eip_r2m_process

• app_weld_set_interface_eip_r2m_mode

• app_weld_set_interface_eip_r2m_test

• app_weld_set_interface_eip_r2m_condition ← (this page)

• 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

Example

// Example: Configure EtherNet/IP welding condition mapping
CONFIG_DIGITAL_WELDING_INTERFACE_CONDITION conditionData;

conditionData._bEnable        = 1;
conditionData._bDataType      = 2;    // Value type signal
conditionData._bPositionalNumber = 1; // Numeric position
conditionData._fMinData       = -5.0; // Min correction (e.g., voltage)
conditionData._fMaxData       = 5.0;  // Max correction (e.g., voltage)
conditionData._bByteOffset    = 6;    // Located at byte 6
conditionData._bBitOffset     = 0;    // Bit offset 0
conditionData._bCommDataType  = 3;    // 8-bit field
conditionData._bMaxDigitSize  = 8;    // 8-bit effective size

bool result = Drfl.app_weld_set_interface_eip_r2m_condition(conditionData);

This example maps a welding condition signal to byte position 6 of the EtherNet/IP output frame. It allows the robot to transmit real-time welding voltage or current correction values to the welder, enabling adaptive condition control synchronized with the robot’s motion path.
