Automatic control function programming manual ladder language

11.1 General
The automatic control function processes priority interrupts on lines:
Machine processor card IT/serial line card USCII card
(max. 2 cards)
1060 series I iti0 to iti3 iti4 to itiB
1060 series II iti0 to iti3 iti4 to itiB
Interrupt Inputs
1060 series II iti0
Priority interrupts are associated with:
- function iti_gr for on-the-fly dimension measurement,
- function thiti to suspend the cyclic tasks of the user programme and execute an interrupt routine programmed in
a %TH hardware task.
11.1.1 On-the-Fly Dimension Measurement
These interrupts are processed by G10 in the part programme (see «PROGRAMMING MANUAL»).
An interrupt sent on one of lines iti0 to itiB is processed by the user programme. As soon as the IT is sent, the monitor
instructs the CNC function to update external parameters E70001 to E78001 (position reference of an axis or group
for on-the-fly measurements).
These external interrupts, dedicated to probing, can be parameterised by function iti_gr().
Interrupt management must be programmed in TS0.
REMARKS With multiple axis groups, if two interrupts arrive at the same time, the interrupt
assigned to line iti0 has the highest priority and that assigned to itiB has the lowest.
If an interrupt assigned to axis group 1 arrives at the same time as an interrupt
assigned to axis group 8 on the same line, the interrupt assigned to group 1 is
processed first by the monitor.
11.1.2 Interrupts Assigned to a %TH Hardware Task
The assignment of a line iti0 to itiB to a hardware task causes execution of the interrupt routine programmed in the
%TH task.
! CAUTION
If a hardware task and a gauging task are assigned and programmed on the same line, the
hardware task is suspended during dimension measurement by the monitor.
