The configurable discrete input options for High-Speed Counter Mode are listed in the table
below. The section on Mode 60 operation at the end of this appendix describes programming
the filter time constants.

* With this feature, you can count 4 times more with the same encoder.
** 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 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 the CPU
does not check for changed preset values, so the DL06 has a faster reset time.
