11.7.1
Parameterization of the number of inputs/outputs used
Maximum number
The maximum number of digital or analog inputs/outputs that can be used for the NC is:
Total
MCI board extension
PROFIBUS modules
Analog inputs
8
-
8
Analog outputs
8
-
8
Digital inputs
36
4
32
Digital outputs
36
4
32
Note
The first digital input and output byte is permanently assigned to the MCI board extension
module (option). Therefore you can connect a maximum of 4 additional input/output bytes to
the PROFIBUS DP via signal modules. See configuration example Subsection
"Configuration example" (Page 473).
Machine data
The number of used analog and digital inputs/outputs is set in the following machine data
parameters:
Analog I/Os
●
MD10300 $MN_FASTIO_ANA_NUM_INPUTS ("number of active analog NC inputs")
●
MD10310 $MN_FASTIO_ANA_NUM_OUTPUTS ("number of active analog NC outputs")
Digital inputs/outputs
●
MD10350 $MN_FASTIO_DIG_NUM_INPUTS ("number of active digital NC input bytes")
●
MD10360 $MN_FASTIO_DIG_NUM_OUTPUTS ("number of active digital NC output
bytes")
