Catch Input
The catch input function is used to receive short pulses from sensor outputs regardless of the scan time. Input pulses shorter than
one scan time can be received. When using catch input, the on/off status according to the status of the external inputs during one
scan is stored in the special internal relays (M8153 to M8157, M8160) that correspond to each external input group, and those
signals can be used as input conditions.
The
Function Area Settings dialog box is used to designate inputs I0, I1, I3, I4, I6 and I7 as a 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.
Catch Input Specifications
Note: Input filter settings have no effect on the catch inputs. For the input filter function, see "Input Filter" on page 5-37.
