.. _struct_CONFIG_DIGITAL_WELDING_INTERFACE_TEST:

CONFIG_DIGITAL_WELDING_INTERFACE_TEST
=====================================

This structure defines the **digital I/O mapping for welding test and auxiliary operations**.  
It configures digital channels used for gas tests, inching control, torch blowout, simulation,  
and optional custom test signals.  
Each field is defined using :ref:`CONFIG_DIGITAL_WELDING_IF_MAPPING_DATA <struct_CONFIG_DIGITAL_WELDING_IF_MAPPING_DATA>`.

.. note::
   - This structure manages **manual testing and setup** features for digital welding systems.  
   - ``_tInchingP`` and ``_tInchingM`` are essential for manual wire control during setup.  
   - ``_tSimulation`` allows validation of I/O communication without actual arc ignition.  
   - Optional fields ``_tTSopt1`` and ``_tTSopt2`` can be repurposed for **custom digital test signals**.
