X Input Configuration
The configurable discrete input options for High-Speed Counter Mode are listed in the table
below. Input X0 is dedicated for the first counter clock input. Input X1 can be the clock for
the second counter or a filtered input. The section on Mode 60 operation at the end of this
appendix describes programming the filter time constants. Inputs X2 and X3 can be
configured as the counter resets, with or without the interrupt option. The interrupt option
allows the reset input (X2 and X3) to cause an interrupt like presets do, but there is no SP
relay contact closure (instead, X2 and X3 will be on during the interrupt routine, for 1 scan).
Or finally, X2 and X3 may be left simply as a filtered input.
*With the counter reset, you have the option of a normal reset or a faster reset. However, the
fast reset does not recognize changed preset values during program execution. When ‘0007’ or
‘0107’ are set in V7636 or V7637 and preset values are changed during program execution,
the DL06 recognizes the changed preset values at the time of the reset. When ‘0207’ or ‘0307’
are set in V7636 or V7637, the CPU does not check for changed preset values, so the DL06
has a faster reset time.
