Description: This machine data prevents stopping at certain blocks with
single block.
Single block stop can be prevented with the following bits of the mask:
Bit0 = 1
Means that there is no stop in any internal ASUB block. Exception: The single block
stop has been explicitly activated by the SBLON command.
There are three different internal ASUBs that are triggered by different events.
- Repos: In the case of the events: change of operating mode to a manual mode (JOG,
JOGREF, etc.) unless MODESWITCH_MASK is not set, switch skip block on and off,
activate machine data, switch-on overstore, axis replacement, subroutine level
cancelation, switch-on single block, switch dry run feedrate on and off, alarm with
compensation block.
- Return: Delete distance-to-go, switchover after TEACH-IN (if available), or
deselection of MDI with corresponding MODESWITCH_MASK.
- _N_PROG_EVENT_SPF: Parameterizing MD 20108 $MC_PROG_EVENT_MASK parameterizes the
events whereby _N_PROG_EVENT_SPF is executed.
Bit1 = 1
Means that there is no stop in any user ASUB block. Exception: The single block stop
has been explicitly activated via the SBLON command.
User ASUBs are linked to an interrupt by the part program command SETINT or via the
PI- _N_ASUP__. The interrupt is then activated via PLC or the high-speed inputs, and
the user ASUBs are retracted.
This disables machine data MD20117 $MC_IGNORE_SINGLEBLOCK_ASUP. The NCK behavior
corresponds to the machine data assignment MD20117 $MC_IGNORE_SINGLEBLOCK_ASUP=
FFFFFFFF.
Bit2 = 1
Means that there is no stop in any intermediate block. Intermediate blocks are
generated at, among other events, tool change, ADIS and complicated geometry.
Bit3 = 1
Means that there is no stop in the block search pickup block. The block search pickup
block
is the
1st block that is loaded into the main run at the start after the search
target has been found in the program.
Bit4 = 1
Means that there is no stop in the INIT blocks. INIT blocks are generated from reset
immediately after a part program start.
Bit5 = 1
Means that there is no stop in any subprogram block with the parameter DISPLOF.
Bit6 = 1
Means that there is no stop in any block in which the NCK cannot reorganize.
Reorganize is an internal procedure that is needed for mode change after JOG/
JOGREF..., switch skip block on and off, activate machine data, axis replacement,
switch on overstore, switch on single block, switch dry run feedrate on and off,
subroutine
level
cancelation,
user ASUBs delete distance-to-go, switchover after TEACH-
IN (if available). Reorganize is never needed in Reset state.
Example blocks in which reorganize is impossible:
● Tool change
● 1st block after the Repos procedure
● Block after an ASUB from JOG/canceled
Bit7 = 1
Means that there cannot be a stop in any block in which repositioning is impossible.
