Description of signals from NC to PLC
DB10
DBB60, 186 - 189 Actual value for digital NCK inputs
Edge evaluation: No
Signal state 1 or edge Signal level "1" is active at the digital hardware input of the NCK.
change 0 → 1
Signal state 0 or edge Signal level "0" is active at the digital hardware input of the NCK.
change 1 → 0
Special cases, The influence of interface signal:
errors, ...... DB10 DBB0 (Disable digital NCK inputs)
is ignored for the actual value.
Corresponding to .... DB10 DBB0 (Disable digital NCK inputs)
MD10350 $MN_FASTIO_DIG_NUM_INPUTS
DB10
DBB64, 190 - 193 Setpoint for digital NCK outputs
Edge evaluation: No
Signal state 1 or edge The NCK value for the digital output currently set (setpoint) is "1".
change 0 → 1
Signal state 0 or edge The NCK value for the digital output currently set (setpoint) is "0".
change 1 → 0
Signal irrelevant for ... This 'setpoint' is only output to the hardware output under the following conditions:
● Output is not disabled (IS "Disable digital NCK outputs")
● PLC has switched to the NCK value (IS "Setting screen form for digital NCK inputs")
As soon as these conditions are fulfilled, the "setpoint" of the digital output corresponds to the "actual
value".
Corresponding to .... DB10 DBB4 (Disable digital NCK outputs)
DB10 DBB5 (Overwrite screen form for digital NCK outputs)
DB10 DBB6 (Setting value by PLC of digital NCK outputs)
DB10 DBB7 (Setting mask for digital NCK outputs)
