Function definition
BOOL LIMIT_E( BOOL EN, ANY_SIMPLE MIN, ANY_SIMPLE S1, ANY_SIMPLE
MAX, ANY_SIMPLE D1 );
Argument
Argument Name IN/OUT Description
EN IN Execution condition (Function is executed only when the result is TRUE)
MIN IN Minimum output limit value
S1 IN Input value
MAX IN Maximum output limit value
D1 OUT Output value
When MIN (lower limit value) > S1 (input value)
.................................................................... D1 = MIN (lower limit value)
When MAX (upper limit value) < S1 (input value)
................................................................... D1 = MAX (upper limit value)
When MIN (lower limit value) S1 (input value) MAX (upper limit value)
............................................................................... D1 = S1 (input value)
Return value
Return Value Description
BOOL Execution condition
Example of use
(*
(*
(*
(* When execution condition X0 turns ON, the iData1 value is stored into Result
if the iData2 data is less than the iData1 data or minimum value, the iData3
value is stored if the iData2 data is greater than the iData3 data or maximum
value, or the iData2 value is stored otherwise.
M0 := LIMIT_E( X0, iData1, iData2, iData3, Result ) ;
