Types of
interrupts
Input interrupts
(4 inputs max.)
Input Interrupt Mode:
Interrupts are executed in response to inputs from external sources to the CPU’s built-in input
points.
Counter Mode:
Interrupts are executed in response to reception of a set number of pulses (counted down) via the
CPU’s internal built-in input points (4 points).
Interval timer
interrupts
Scheduled Interrupt Mode:
Program is interrupted at regular intervals measured by one of the CPU’s internal timers.
(3 timers max.)
One-shot Interrupt Mode:
An interrupt is executed after a set time, measured by one of the CPU’s internal timers.
High-speed counter Target Value Comparison:
interrupts Interrupt is executed when the high-speed counter PV is equal to a specified value.
Range Comparison:
Interrupt is executed when the high-speed counter PV lies within a specified range.
Counting is possible for high-speed counter inputs from the CPU’s internal input points, Pulse I/O
Boards, or Absolute Encoder Interface Boards. (The High-speed Counter Board has no interrupt
function, but can output bit patterns internally and externally.)
I/O allocations
I/O is automatically allocated in order from the Unit nearest to the CPU. (Because there are no I/O
tables, it is not necessary to create I/O tables from a Programming Device.)
