EXTERN_INTERRUPT_BITS_M96
The flow of the interrupt routine activated with M96P can be affected by setting the different
bits.
Bit 0=0: Interrupt program is not possible, M96/97 are normal M functions
Bit 0=1: Activation of an interrupt program with M96/M97 is allowed
Bit 1=0: Process part program with the end position of the next block after the interruption
block
Bit 1=1: Further process part program from the interruption position
Bit 2=0: the interrupt signal interrupts the current block immediately and starts the interrupt
routine
Bit 2=1: the interrupt routine is started only at the end of the block
Bit 3=0: Interrupt execution cycle during an interrupt signal
Bit 3=1: Start interrupt program only at the end of the execution cycle
EXTERN_MEAS_G31_P_SIGNAL
Assignment of the measuring inputs for G31 P..
min. input limit: 0
The machine data is used to define an assignment of the measuring inputs 1 and 2 to the P
number programmed with G31 P1 (-P4). The MD is bit-coded. Only Bit 0 and Bit 1 are
evaluated. If, e.g. the Bit 0=1 is in $MN_EXTERN_MEAS_G31_P_SIGNAL[1], it is activated
with G31 P2 of the first measuring input. The second measuring input is activated with G31
P4 with $MN_EXTERN_MEAS_G31_P_SIGNAL[3] = 2.
Bit 0=0: Do not evaluate measuring input 1 in G31 P1 (-P4)
Bit 0=1: Activate measuring input 1 in G31 P1 (-P4)
Bit 1=0: Do not evaluate measuring input 2 in G31 P1 (-P4)
Bit 1=1: Activate measuring input 2 in G31 P1 (-P4)
EXTERN_DOUBLE_TURRET_ON
Double turret head with G68
min. input limit:
The machine data is effective only in $MN_EXTER_CNC_SYSTEM = 2. This MD is used to
define whether a double-slide machining is to be started with G68 (channel synchronization
for the 1st and 2nd channel), or the second tool of a double turret (= 2, tool permanently
connected at the distance defined in MD $SC_EXTERN_DOUBLE_TURRET_DIST) is to be
activated.
FALSE: Channel synchronization for double-slide machining
TRUE: 2. Change tool of a double turret (= activate
$SC_EXTERN_DOUBLE_TURRET_DISTANCE as additive work offset and mirroring at Z
axis
