Constant: LTIME

Syntax

<long time keyword> # <length of high resolution time>

<long time keyword> : LTIME | ltime
<length of high resolution time> : <length of time> ( <number of microseconds>us )?  ( <number of nanoseconds>ns )? // ( ...)? Optional

You can use the same units for ‎LTIME‎ constants as for ‎TIME‎ constants. You can also specify microseconds and nanoseconds because the specified time is calculated in higher time resolution. ‎LTIME‎ literals are treated internally as data type ‎LWORD‎ and therefore the value resolved in nanoseconds.

Additional time units

‎US | us‎: Microseconds
‎NS | ns‎: Nanoseconds

Examples of correct usage of an ST assignment

PROGRAM PLC_PRG
VAR
        ltimLength := LTIME#1000d15h23m12s34ms2us44ns;
        ltimLength1 := LTIME#3445343m3424732874823ns;
END_VAR
