Detailed Description
2.2 Axis monitoring, protection zones (A3)
NC/PLC Interface Signals (Z1)
2-66 Function Manual, 08/2005 Edition, 6FC5397-0BP10-0BA0
DB21, ...
DBX274.0 –
DBX275.1
Channel-specific protection zone 1 (...10) pre-activated
Signal state 0 or
edge change
1 → 0
The channel-specific protection zone 1 ( ...10) is deactivated in the current block.
(De-activated in the part program.)
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
to ....
DB21, ... DBX10.0 - DBX11.1 (activate channel-specific protection zone 1 (...10))
DB21, ...
DBX276.0 –
DBX277.1
Machine-related protection zone 1 (...10) violated
Edge evaluation: no Signal(s) updated: cyclic
Signal state 1 or
edge change
0 → 1
The activated, machine-related protection zone 1 ( ...10) is violated in the current block or in the
current JOG movement.
The pre-activated, machine-related protection zone 1 ( ...10) would be violated in the current block
if it would be activated by the PLC.
Signal state 0
or edge change
1 → 0
The activated, machine-related protection zone 1 (...10) is not violated in the current block.
The pre-activated, machine-related protection zone 1 (...10) would not be violated in the current
block if it would be activated by the PLC.
Application
example(s)
Before parts are moved into the working zone - this IS can be used to check as to whether the tool
or workpiece is located in the machine-related protection zone of the part to be moved in.

DBX278.0 -
DBX279.1
Channel-specific protection zone 1 (...10) violated
Edge evaluation: no Signal(s) updated: cyclic
Signal state 1 or
edge change
0 → 1
The activated, channel-specific protection zone 1 ( ...10) is violated in the current block.
The pre-activated, channel-specific protection zone 1 ( ...10) would be violated in the current block
if it would be activated by the PLC.
Signal state 0 or
edge change
1 → 0
The activated, channel-specific protection zone 1 ( ...10) is not violated in the current block.
The pre-activated, channel-specific protection zone 1 (...10) would not be violated in the current
block if it would be activated by the PLC.
Application
example(s)
Before parts are moved into the working zone - this IS can be used to check whether the tool or
workpiece is located in the channel-specific protection zone of the part to be moved-in.
