• When executed, the TTMR instruction implements time measurement. Do not use the JMP instruction to
skip the TTMR instruction. Otherwise, accurate measurement is disabled.
• Do not change the multiplier specified by (s) during execution of the TTMR instruction. Otherwise, accurate
values cannot be determined.
• The device specified by (d)+1 is used by the system of the CPU module. Do not change the value. If the
value is changed, an accurate resultant value is not stored in the device specified by (d).
• When the value in the device specified by (s) is not in the range from 0 to 2, no processing is performed.
