5.19.6 32-bit data bit zone control DZONE_MD
The output value is zone-controlled with a bias value added to the specified BIN 32-bit data.
Function definition
BOOL DZONE_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
Negative bias value added to input value (BIN 32-bit
data)
S2 IN Positive bias value added to input 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 S3 (input value) < 0
......................S3 (input value) + S1 (negative bias value) D (output value)
When S3 (input value) = 0 ...............................................0 D (output value)
When S3 (input value) > 0
....................... S3 (input value) + S1 (positive bias value) D (output value)
Return Value Description
BOOL Execution condition
Example of use
(* When execution condition X0 turns ON, the bias value specified in iData1 or *)
(* iData2 is added to the input value specified in iData3, and the result is stored *)
(* into Result.
*)
DZONE_MD (X0, dData1, dData2, dData3, Result);
