5.19.2 32-bit data upper/lower limit control DLIMIT_MD
The output value is controlled depending on whether the specified BIN 32-bit data is within the upper/lower limit
value range or not.
Function definition
BOOL DLIMIT_MD (BOOL EN, ANY32 S1, ANY32 S2, ANY32 S3, ANY32 D);
Argument Name IN/OUT Description
EN IN
Execution condition (Function is executed only when the
result is TRUE)
S1 IN Lower limit value (BIN 32-bit data)
S2 IN Upper limit value (BIN 32-bit data)
S3 IN Input value (BIN 32-bit data)
D OUT Output value (BIN 32-bit data)
Remarks: The output value is controlled as described below.
When S1 (lower limit value) > S3 (input value)
......................................................... S1 (lower limit value) D (output value)
When S2 (upper limit value) < S3 (input value)
.........................................................S2 (upper limit value) D (output value)
When S1 (lower limit value) ≤ S3 (input value) ≤ S2 (upper limit value)
..................................................................S3 (input value) D (output value)
Return Value Description
BOOL Execution condition
Example of use
(* When execution condition X0 turns ON, the output value is stored into Result *)
(* depending on whether or not the input value specified in dData3 is within the *)
(* upper/lower limit value range specified in dData1 and dData 2.
*)
DLIMIT_MD (X0, dData1, dData2, dData3, Result);
