Timer Function Block

TIMER__M
These function blocks start counting a timer when the execution condition is satisfied, and continue counting until the timer
reaches the set value.

d1 (ValueOut) Current timer value
d2 (Status) Output
Processing details
■TIMER_HIGH_FB_M
• This is a high-speed timer whose unit of measurement is 0.1 to 100 ms. When (s1) turns on, measurement of the current
value starts. The measurement starts from (s3)×0.1 to 100 ms (variable; set in parameter). When the value reaches
(s2)×0.1 to 100 ms, (d2) turns on. The measured current value is output to (d1).
• When (s1) turns off, the current value returns to the initial value (s3), and (d2) also turns off.
• The unit of measurement of the high-speed timer is 10 ms by default. The unit can be changed in the range from 0.01 to
100 ms.
• The valid setting range of (s2) is 0 to 32767.
• The valid setting range of (s3) is -32768 to 32767. Note that if a negative value is specified, 0 will be used as the initial
value.
