Mnemonic Function
TMR 16-bit timer
T-K T0~T15, K0~K32,767
Operand
T-D T0~T15, D0~D29
Explanations:
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
Program Example:
Ladder diagram: Command code: Operation:
LD X0 Load contact A of X0 T5 timer
X0
T5TMR
K1000
TMR T5 K1000 Setting is K1000
Remarks: Please refer to the specification for the operand T usage.
