DB10
DBB168 Disable analog NCK outputs
Edge evaluation: No Signal(s) updated: Cyclic
Signal state 1 or
edge change 0 → 1
The analog output of the NCK is disabled. "0V" is output in a defined way at the hardware output.
Signal state 0 or
edge change 1 → 0
The analog output of the NCK is enabled. As a result, the value set by the NC part program or the
PLC is output at the hardware output.

DBB170 - 185 Setting value from PLC for analog NCK outputs
Edge evaluation: No Signal(s) updated: Cyclic
Signal state 1 or
edge change 0 → 1
With this setting value, the value for the analog hardware output can be changed by the PLC.
There are two possibilities:
• With the "Overwrite screen form":
With signal transition 0 → 1 in the 'overwrite screen form' the PLC overwrites the previous 'NCK
value' with the 'setting value'. This is the new "NCK value".
• With the "setting screen form":
On signal state 1 in the "setting screen form", the "PLC value" is activated. The value used is
the 'setting value'.
The setting value from the PLC is specified as a fixed point number (16 bit value including sign) in
2's complement.
Signal state 0 or
edge change 1 → 0
As the interface signal is only evaluated by the NCK on signal transition 0 → 1 it must be reset to
"0" again by the PLC user program in the next PLC cycle.
Special cases,
errors, ....
Note:
The PLC interface for the setting value is used both by the overwrite screen form (for signal
transition 0 → 1) and the setting screen form (for signal state 1). Simultaneous activation of the two
screen forms must be avoided via the PLC user program.
