Operands:
D: Device No. for storing the “On” time of button switch n: Multiple setting
Explanations:
1. D will occupy 2 consecutive devices.
2. Range of n: 0 ~ 2
3. See the specifications of each model for their range of use.
4. For SA series MPU, TTMR instruction can be used 8 times in the program.
5. The “On” time (unit: 100ms) of the external button switch is stored in device No. D + 1. The “On” time (unit:
second) of the switch is multiplied by n and stored in D.
6. Multiple setting:
When n = 0, unit of D = second
When n = 1, unit of D = 100ms (D × 10)
When n = 2, unit of D = 10ms (D × 100)
Program Example 1:
1. The “On” (being pressed) time of button switch X0 is stored in D1. The setting of n is stored in D0. Therefore, the
button switch will be able to adjust the set value in the timer.
2. When X0 goes Off, the content in D1 will be cleared to 0, but the content in D0 will remain.

3. Assume the “On” time of X0 is T (sec.), see the relation between D0, D1 and n in the table below.
n D0 D1 (unit: 100ms)
K0 (unit: s) 1 × T D1 = D0 × 10
K1 (unit: 100 ms) 10 × T D1 = D0
K2 (unit: 10 ms) 100 × T D1 = D0/10
