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 has to be defined in the configuration list of hardware. Both parameters are important only, if direct access via driver functions is wished. In this case the parameter 'cam_direkt_access' has to be set to value TRUE. In the other case the cam signals are read via PLC-interface (HLI-Interface or axis specific control interface of path interpolator).
