Z1: NC/PLC interface signals
19.2 Axis monitoring, protection zones (A3)
DB21, ...
DBX10.0 - DBX11.1
Activate channel-specific protection zone 1 ( ...10)
Signal state 0 or
The pre-activated, channel-specific protection zone 1 ( ...10) is de-activated by the PLC user program.
edge change
The protection zone is immediately de-activated.
1 → 0
Only protection zones that have been activated via the PLC and have been pre-activated in the NC
part program can be de-activated.
Application exam‐
Before a synchronous spindle, for example, is moved into the working range, the relevant machine-
ple(s)
related protection zone can be activated.

Signals from channel (DB21, ...)
DB21, ...
DBX272.0 –
Machine-related protection zone 1 ( ...10) pre-activated
DBX273.1
Edge evaluation: No
Signal state 1 or
The machine-related protection zone 1 ( ...10) is preactivated in the current block.
edge change
(Pre-activated in the part program).
0 → 1
The protection zone can therefore be activated or de-activated in the PLC user program using the
interface signal:
DB21, ... DBX8.0 - DBX9.1 (machine-related protection zone 1 (...10))
Signal state 0 or
The machine-related protection zone 1 ( ...10) is deactivated in the current block.
edge change
(De-activated in the part program).
1 → 0
The protection zone can therefore not be activated or de-activated in the PLC user program using
the interface signal:
DB21, ... DBX8.0 to DBX9.1 (activate machine-related protection zone 1 (...10))
Corresponding
DB21, ... DBX8.0 - DBX9.1 (activate machine-related protection zone 1 (...10))

DBX274.0 –
Channel-specific protection zone 1 (...10) pre-activated
DBX275.1
Edge evaluation: No
Signal state 1 or
The channel-specific protection zone 1 ( ...10) is preactivated in the current block.
edge change
(Pre-activated in the part program).
0 → 1
The protection zone can therefore be activated or de-activated in the PLC user program using the
interface signal:
DB21, ... DBX10.0 - DBX11.1 channel-specific protection zone 1 (...10))
Signal state 0 or
The channel-specific protection zone 1 ( ...10) is deactivated in the current block.
edge change
(De-activated in the part program.)
1 → 0
The protection zone can therefore not be activated or de-activated in the PLC user program using
the interface signal:
DB21, ... DBX10.0 - DBX11.1 (channel-specific protection zone 1 (...10))
Corresponding
