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.

TIMER_10_FB_M
• When (s1) turns on, measurement of the current value starts. The measurement starts from (s3)

10ms. When the value
reaches (s2)

10ms, (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 (s2) also turns off.
• If the unit of measurement of the high-speed timer (in the timer limit setting) is changed from the default value using the
engineering tool, a warning will be issued during compilation.
• 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.
• [RnPCPU (redundant)] If these function blocks are used in a program executed in both systems, there are restrictions on their operation when the systems
are switched. (  MELSEC iQ-R CPU Module User's Manual (Application))
