DVP-ES3 Series Programming Manual one out of four input modes can be used in PLC programing. For example, if HC200 is edited, the HC20-HC203 can no longer be edited. Note 2: -- indicates that the counting mode is reserved and not available now. An empty box indicates no function. Note3: refer to the SM/SR table for count up/down state selection and the number of times for frequency input. Note 4: the R function (reset input) is disabled by default. Refer to the SM/SR comparison table for how to use R. Take HC200 for example. SM291 switches to ON to start the R function and then the rising edge of X14 triggers clearing the value of HC200.
If there is no built-in input points, including X14 ~ X17, in the PLC you are using, you can use external interrupts or use counter eraser instructions to clear the counters.
