Operands:
S
: Timer number (T0~T191)
m
: Set-point value of the timer (
m
=1~32,767), units in 100ms
D
: Starting address of the results (occupies 4 continuous bits)
Description:
1. The STMR instruction can be used for OFF-delay, ON/OFF triggering, or as a flashing circuit.
2. The timer number (
S
) specified by STMR instruction can be used only once.
3. Range of
S
: for ELC-PC/PA/PH T0 ~ T191; for ELC-PV T0 ~ T199
Program Example:
1. The preset value of timer T0 is 5 seconds.
2. Y0 is the OFF-delay output :
a) When X20 turns from OFF → ON, Y0= ON.
b) When X20 turns ON → OFF after a delay 5 seconds, Y0=OFF.
c) When X20 turns from ON → OFF, Y1= ON for 5 seconds, then turns Off.
d) When X20 turns from OFF → ON, Y2=ON for 5 seconds, then turns Off.
e) When X20 turns from OFF → ON, Y3=ON after a 5 second delay.
f) When X20 turns from ON → OFF, Y3=OFF after a 5 second delay.

g) Add a b contact addressed with Y3 (LDI Y3) in series with contact X20. Then Y1 and Y2
can be used for a flash circuit. Y1 and Y2 will alternate, each on for 5 seconds, then off for
5 seconds. When X20 turns OFF, Y0, Y1 and Y3 = OFF and the content of T10 will be
