Description of signals from NC to PLC
DB10
DBB60, 186 - 189 Actual value for digital NCK inputs
Edge evaluation: No
Signal state 1 or Signal level "1" is active at the digital hardware input of the NCK.
edge change 0 → 1
Signal state 0 or Signal level "0" is active at the digital hardware input of the NCK.
edge change 1 → 0
Special cases, The influence of interface signal:
errors, ...... DB10 DBB0 (Disable digital NCK inputs)
is ignored for the actual value.

DB10
DBB64, 190 - 193 Setpoint for digital NCK outputs
Edge evaluation: No
Signal state 1 or The NCK value for the digital output currently set (setpoint) is "1".
edge change 0 → 1
Signal state 0 or The NCK value for the digital output currently set (setpoint) is "0".
edge change 1 → 0
Signal irrelevant for This "setpoint" is only output to the hardware output under the following conditions:
...
•
•
As soon as these conditions are fulfilled, the "setpoint" of the digital output corresponds to the
"actual value".

DB10
DBB194 - 209 Actual value for analog NCK inputs
Edge evaluation: No
Signal state 1 or The analog value applied to the analog NCK input is signalled to the PLC.
edge change 0 → 1
The actual value is set as a fixed point number (16 bit value including sign) in 2's complement by
the NCK.
Signal state 0 or The effect of the PLC on the analog value (e.g. with IS "Disable analog NCK inputs") is ignored.
edge change 1 → 0
