■
PULSE COUNT RESET
In n+0 word of the output data from host PC/PLC, the bits to reset the totalized values of the respective channels are allocated.
By changing the bits from 0 to 1, the totalized values of the respective channels are reset.
Confirm that the totalized values are reset, and return the bits to 0.
Note that the next reset will not work if the reset bits remain at 1.
■
PULSE COUNT PRESET
Write the desired preset values in n+2 word and n+3 word of the output data from host PC/PLC.
The bits to preset the totalized values of the respective channels are allocated in n+1 word.
By changing the bits from 0 to 1, the preset values are reflected to the totalized values of the respective channels.
Confirm that the totalized values are preset, and return the bits to 0.
Note that the next preset will not work if the preset bits remain at 1.
