6.2.3.8

$NP_BIT_NO

Function
Enter the bit number of an NC/PLC interface signal of the 64-bit wide interface with which the
protection area is to be connected in system variable $NP_BIT_NO. If the protection area is
not to be connected to an NC/PLC interface signal, enter the value -1.
NC/PLC interface
Activation / deactivation of the protection area can be requested via NC/PLC interface signals
via the PLC user program or this can be used for feedback on the current status to the PLC
user program:
● Requirement: DB10, DBX234.0 - DBX241.7 (Page 809)
● Feedback: DB10, DBX226.0 - DBX233.7 (Page 810)
Precondition
The status of the protection area must be "preactivated" or "PLC-controlled" in order for the
NC/PLC interface of the protection area to be observed. $NP_INIT_STAT (Page 230) == "P"
(preactivated or PLC-controlled)
