Add an interrupt

Use the
New interrupt
 dialog to create interrupts for
Micro800
 controller programs. The available interrupt types vary with the controller selection. When you are adding, configuring, or deleting interrupts, the controller must be offline.
Use interrupts to:
  • Set time intervals between executions of ladder subroutines.
  • Force user interrupt functions to start without using ladder logic.
  • Allow or prohibit overflows and underflows for high-speed counter (HSC) interrupts.
  • Allow or prohibit high and low presets for HSC interrupts.
Prerequisites
  • Create a
    Micro800
     controller project.
  • The controller is offline.

  1. In
    Project Organizer
