Special function timer
STMR
*1 Can be used only by timer (T) data
• The STMR instruction uses the 4 points from the device designated by (D) to perform four types of timer output.
• The timer coil designated by (S) turns ON at the rising edge and falling edge of the command for the STMR instruction, and
starts measurement of the present value.
(S): Timer number (word)
n: Value to set (BIN 16 bits).
(D): (D)+0: Off delay timer output (bits)
(D)+1: One shot timer output after OFF (bits)
(D)+2: One shot timer output after ON (bits)
(D)+3: ON delay and Off delay timer output (bits)

Item Description
OFF delay timer output ((D)+0) Goes ON at the rising edge of the command for the STMR instruction, and
after the falling edge of the command, goes OFF when the amount of time
designated by n has passed.
One shot timer output after OFF ((D)+1) Goes ON at the falling edge of the command for the STMR instruction, and
goes OFF when the amount of time designated by n has passed.
One shot timer output after ON ((D)+2) Goes ON at the rising edge of the command for the STMR instruction, and
goes OFF either when the amount of time designated by n has passed, or
when the command for the STMR instruction goes OFF.
ON delay timer output ((D)+3) Goes ON at the falling edge of the timer coil, and after the falling edge of the
command for the STMR instruction, goes OFF when the amount of time
designated by n has passed.
• The timer coil measures to the point where the value reaches the set value designated by n, then enters a time up state and goes OFF.
• If the command for the STMR instruction goes OFF before the timer coil reaches the time up state, it will remain ON. Timer measurement is continued at this
time. When the STRM instruction command goes ON once again, the present value will be cleared to 0 and measurement will begin once again.
