(Note 1): X6 can be used for either CH6 count input or CH0 reset input. X7 can be used for CH7 count input or CH2
reset input.
(Note 2): Only F1 (DMV) instruction can perform the reading and writing of elapsed value area.
About max. count speed
The max. count speed indicates the situation when executing each item condition (output
mode, channel) only. It indicates the value when not performing high-speed counter
consistent ON (F166) instruction, high-speed counter consistent OFF (F167) instruction, pulse
output function and other interruption handling control. For the performance when these
functions are used concurrently, please contact us.
