When the RST command is driven, the action of the designated element will be as
follows:
Element Mode
Y, M Both coil and contact will be set as Off.
T, C
The current timing or count value will be set as 0, and both the coil
and contact ill be set as Off.
D The content value will be set as 0.
If the RST command has not been executed, the status of the designated element will
remain unchanged.

When the TMR command is executed, the designated timer coil will be electrified, and
the timer will begin timing. The contact's action will be as follows when the timing
value reaches the designated set value (timing value >= set value):
NO (Normally Open) contact Closed
NC (Normally Close) contact Open
If the RST command has not been executed, the status of the designated element will
remain unchanged.

16-bit counter
Operand

C0~C79，D0~D399
When the CNT command is executed from Off→On, this indicates that the designated
counter coil goes from no power → electrified, and 1 will be added to the counter's
count value; when the count reaches the designated value (count value = set value),
the contact will have the following action:
NO (Normally Open) contact Closed
NC (Normally Close) contact Open
After the count value has been reached, the contact and count value will both remain
unchanged even if there is continued count pulse input. Please use the RST
command if you wish to restart or clear the count.
