Assignment of inputs/outputs to the signal modules
On the NC side, the analog and digital inputs/outputs are assigned to the respective signal
modules on the PROFIBUS DP via the appropriate I/O addresses in the machine data:
Machine data
Analog I/Os
●
MD10362 $MN_HW_ASSIGN_ANA_FASTIN[n] ("hardware assignment of external analog
inputs") per input, where n = 0-7
●
MD10364 $MN_HW_ASSIGN_ANA_FASTOUT[n] ("hardware assignment of external
analog outputs") per output, where n = 0-7
Digital inputs/outputs
●
MD10366 $MN_HW_ASSIGN_DIG_FASTIN[n] ("hardware assignment of external digital
inputs"), per input byte - where n = 0-3
●
MD10368 $MN_HW_ASSIGN_DIG_FASTOUT[n] ("hardware assignment of external
digital outputs"), per outputbyte - where n = 0-3

Note
•
The relevant firstdigital inputs/outputs bytes defined via the following machine data is
related to the 4 digital inputs/outputs of the MCI board extension module:
–
MD10350 $MN_FASTIO_DIG_NUM_INPUTS
–
MD10360 $MN_FASTIO_DIG_NUM_OUTPUTS
Explicit assignment in machine data is not possible. Therefore, the machine data
required to assign the digital and analog inputs/outputs refer exclusively to the signal
modules connected via the PROFIBUS DP.
•
The I/O address to be entered in the machine data hexadecimally is the decimal I/O
address of the respective signal module slot allocated by "HW Config" or set manually.
•
If a slot comprises several I/O bytes or addresses the NC occupies the entire slot when
an I/O byte is assigned. This means I/O bits not used for the NC cannot be written by the
PLC user program .
