Operands:
D
: Device for storing the measuring time (unit: 1us)
n
: Measurement time base. Parameter range: K10 ~ K500
(time unit: 1us)
Explanations:
1. Range
of
D
: K0 ~ K9
2. Range
of
n
: K10 ~ K500
3.
The designated special D registers (D1156 ~ D1165) can measure up to 10 interruption subroutines. For
example, when
D
= K5, the designated D register will be D1161.
4.
When RTMU is executed, if the
D
and
n
entered by the user are legal, interruption of the timer will be enabled
and the counting starts and the special D designated by
D
is cleared as 0. When RTMD is executed,
interruption of the timer is disabled and the calculated time will be assigned to special D designated by RTMD.
5.
With API 153 RTMD, RTMU can measure the execution time of “I” interruption service subroutine, which can
be reference for dealing with the high-speed response when the user is at the initial stage of developing the
program.

Operands:
D
: Device to store the measuring time (unit: 1us).
Explanations:
1. Range
of
D
: K0 ~ K9. The No. of
D
has to be the same as that designated by
D
in API 152 RTMU; otherwise the
result of the measurement may be unexpectable.
Program Example:
When X0 goes from Off to On, the program will enter I001 interruption subroutine. RTMU will activate an 8-bit timer
(unit: 10us) and RTMD (when D = K0) will shut down the timer and store the time in the timer in special D registers
(D1156 ~ D1165, designated by K0 ~ K9).
