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.
