Interrupt Input
When a quick response to an external input is required, such as positioning control, the interrupt input can call a subroutine to
execute an interrupt program.
Six inputs I0, I1, I3, I4, I6, and I7 can be designated to execute interrupt at a rising and/or falling edge of input pulses. When an
interrupt is initiated by inputs I0, I1, I3, I4, I6 and I7, program execution immediately jumps to a predetermined label number
stored in special data registers D8215, D8032 through D8035, and D8214 respectively. The
Function Area Settings dialog box is
used to designate inputs I0, I1, I3, I4, I6 and I7 as an interrupt input, normal input, high-speed counter input, or catch input.
Normal input signals to input terminals are read when the END instruction is executed at the end of a scan.
Since these settings relate to the user program, the user program must be downloaded to the FC6A Series MICROSmart after
changing any of these settings.
