System variable
The status of the current block can be determined via the system variable $P_IPTRLOCK:
$P_IPTRLOCK
Automatic function-specific "Continue machining at the contour" lock
For various couplings, the activation/deactivation of the "Continue machining at the contour"
lock can be performed automatically channel-specifically with the activation/deactivation of the
coupling:
MD22680 $MC_AUTO_IPTR_LOCK, bit x
Bit
0
1
This program section begins with the last executable block before the activation and ends with
the deactivation.
