Interrupt block preparation
Same as in the CNC channel, blocks are also prepared in advance in the PLC channel.
The value of P100 may be different before, during and after the movement of the W axis. If it is to
be analyzed after moving the axis, function G4 must be programmed.
Likewise, every time a PLC resource is accessed (I, O, M, R), block preparation is interrupted.
Auxiliary M functions
The M functions programmed in the PLC channel may be defined in the M function table.
In the PLC channel, the following functions cannot be programmed: M0, M1, M2, M3, M4, M5, M6,
M19, M30, M41, M42, M43 and M44.
The following marks and registers are generated for managing the M functions, :
CNCEX (G1 W100, M101)
Movement of the W axis.
CNCEX (IF P100=0 <action1>)
P100 is analyzed during block preparation.
CNCEX (G1 W100, M101)
Movement of the W axis.
CNCEX (G4, M102)
Interrupts block preparation.
CNCEX (IF P100=0 <action1>)
P100 is analyzed after moving the axis.
CNCEX (G1 W100, M101)
Movement of the W axis.
CNCEX (IF PLCI8=1 <action2>)
I8 is checked after moving the axis.
MBCDP1 through MBCDP7 (R565 through R571)
similar to signals MBCD1 through MBCD7.
AUXENDP (M5006)
Similar to the AUXEND signal.
MSTROBEP (M5505)
Similar to the MSTROBE signal.
