# Parameters of digital input interface for homing cams

With the system-wide distinctive name of hardware (name of I/O-interface card) 'cam_hw_id_string' and the bit variable 'cam_mask'' one physical digital input is defined clearly. With 'cam_level' the signal level is defined. The selected hardware must be defined in a hardware configuration list [ Both parameters are important onl, if direct access via driver functions is required. In this case the parameter 'cam_direkt_access' has to be set to value TRUE. Otherwise, the cam signals are read via the PLC interface (HLI interface or the axis-specific control interface of the path interpolator).
