Less Than or Equal
For integer, REAL, TIME, DATE, and STRING variables, compares input variables to determine whether the first is less than or equal to the second.
For TON, TP, TOF, BLINK, and StepName.t in SFC chart, equality testing of TIME variables is not recommended.
Arguments | ||
|---|---|---|
i1 | SINT - USINT - BYTE - INT - UINT - WORD - DINT - UDINT - DWORD - LINT - ULINT - LWORD - REAL - LREAL - TIME - DATE - STRING | Both inputs must have the same type. |
i2 | SINT - USINT - BYTE - INT - UINT - WORD - DINT - UDINT - DWORD - LINT - ULINT - LWORD - REAL - LREAL - TIME - DATE - STRING | |
o1 | BOOL | TRUE if i1 <= i2 |
Example
(* FBD example with "Less or Equal to" Operators *)
(* ST Equivalence: *)
aresult := (10 <= 25); (* aresult is TRUE *) mresult := ('ab' <= 'ab'); (* mresult is TRUE *)
