Mnemonic Function
TMR 16-bit timer
T-K T0~T159, K0~K32,767
Operand
T-D
T0~T159, D0~D399
When TMR command is executed, the specific coil of timer is ON and timer will start to
count. When the setting value of timer is attained (counting value >= setting value),
the contact will be as following
NO(Normally Open) contact
Open
collector
NC(Normally Closed) contact
Close
collector
When the RST command is not driven, motion of its specific device remains
unchanged.
Command code: Operation:
LD X0 Load contact A of X0

Setting of T5 counter
is K1000.
Mnemonic Function
CNT Clear contact or register
C-K C0~C79, K0~K32,767
Operand
C-D
C0~C79, D0~D399
When the CNT command is executed from OFFÆON, which means that the counter
coil is driven, and 1 should thus be added to the counter’s value; when the counter
achieved specific set value (value of counter = the setting value), motion of the
contact is as follows:
NO(Normally Open) contact
Open
collector
NC(Normally Close) contact
Close
collector
If there is counting pulse input after counting is attained, the contacts and the counting
values will be unchanged. To re-count or to conduct the CLEAR motion, please use
the RST command.
Command code: Operation
LD X0 Load contact A of
