2.5.4 Parameter settings for input signals (840Di)
The following input signals must be parameterized in the machine data:
• Clearance sensor input voltage
• "Sensor collision" input signal (optional)
Analog input
The following machine data must be parameterized for the analog input:
• MD10300 $MN_FASTIO_ANA_NUM_INPUTS (number of active analog NCK inputs)
• MD10362 $MN_HW_ASSIGN_ANA_FASTIN (hardware inputs for the fast analog NCK
Digital input
Subsequent parameter settings do not have to be made if a digital input on the MCI board
extension module (option) is used.
If an I/O module on PROFIBUS-DP is used for the digital input, the following machine data
must be parameterized:
• MD10350 $MN_FASTIO_DIG_NUM_INPUTS (number of active digital NCK input bytes)
• MD10366 $MN_HW_ASSIGN_DIG_FASTIN (hardware assignment for the external digital
