■Operation processing
[TIMER_10_FB_M]
• Starts measuring the current value when the executing condition of (s1) turns ON.
• Starts measuring from the value input to (s3)  10ms, and when the measuring value reaches to the value input to (s2) 
10ms, (d2) turns ON.
• The current value is output from (d1).
• When the executing condition of (s1) turns OFF, the current value is set to the value input to (s3), and (d2) turns OFF.
• When the unit of measurement (time period) for the high-speed timer is changed from default value of PLC parameter,
warning C9047 occurs in compilation.
• Valid setting range for (s2) is 0 to 32767.
• Valid setting range for (s3) is -32768 to 32767. However, if negative value is specified, the initial value is 0.
[TIMER_100_FB_M]
• Starts measuring the current value when the executing condition of (s1) turns ON. Starts measuring from the value input to
(s3)  100ms, and when the measuring value reaches to the value input to (s2)  100ms, (d2) turns ON.
• The current value is output from (d1).
• When the executing condition of (s1) turns OFF, the current value is set to the value input to (s3), and (d2) turns OFF.
• When the unit of measurement (time period) for the low-speed timer is changed from default value of PLC parameter,
warning C9047 occurs in compilation.
• Valid setting range for (s2) is 0 to 32767.
• Valid setting range for (s3) is -32768 to 32767. However, if negative value is specified, the initial value is 0.
