The comparison between the UDCNTF instruction and HIOEN/
DHIOEN instruction
The comparison between the UDCNTF instruction and the HIOEN/DHIOEN instruction is described below.

: Not use
The LC device can be used as a high-speed counter only when the FX3 compatible function is valid. However,
this is only the LC device that is set up with parameter. Also, it is possible to use the HIOEN/DHIOEN
instruction.

When output has operated
Description
This is the activation contact to start the counting of the LC device. When the UDCNTF instruction is turned OFF/ON, the
status turns ON and the counting of the input signal becomes possible.
This is K specified with UDCNTF LC K. An indirect specification is acceptable.
This is the current value of the counter. The value increases or decreases depending on the input pulse.
This turns ON when the current value of the LC device changes from a value less than the setting value to the setting
value or higher. This can be used as LD LC.
This turns ON when the RST instruction with the LC device specified turns OFF→ON, and turns OFF when the RST
instruction turns ON→OFF. When the reset coil is ON, the counting is not executed even if the count coil is ON, and the
current value is always 0.
