19.2.2 Signals from channel (DB21, ...)
Signal state 0 or
edge change
1 → 0
The pre-activated, channelspecific protection zone 1 ( ...10) is de-activated by the PLC user
program.
The protection zone is immediately de-activated.
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
example(s)
Before a synchronous spindle, for example, is moved into the working range, the relevant
machinerelated protection zone can be activated.
DB21, ...
DBX272.0 –
DBX273.1
Machinerelated protection zone 1 ( ...10) pre-activated
Edge evaluation: no Signal(s) updated: cyclic
Signal state 1 or
edge change
0 → 1
The machinerelated protection zone 1 ( ...10) is preactivated in the current block.
(Pre-activated in the part program).
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
edge change
1 → 0
The machinerelated 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, ... DBX8.0 to DBX9.1 (activate machine-related protection zone 1 (...10))
Corresponding
to ....
DB21, ... DBX8.0 - DBX9.1 (activate machine-related protection zone 1 (...10))
DB21, ...
DBX274.0 –
DBX275.1
Channelspecific protection zone 1 (...10) pre-activated
Edge evaluation: no Signal(s) updated: cyclic
Signal state 1 or
edge change
0 → 1
The channelspecific protection zone 1 ( ...10) is preactivated in the current block.
(Pre-activated in the part program).
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
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, ...
DBX10.0 - DBX11.1 Activate channelspecific protection zone 1 ( ...10)
