Bit Zone Control - Mitsubishi Electric MELSEC Q Series Programming Manual

5 MELSEC FUNCTIONS

5.19.5 Bit zone control

The output value is zone-controlled with a bias value added to the specified BIN 16-bit data.
Function definition
5- 103
ZONE_MD
BOOL ZONE_MD (BOOL EN, ANY16 S1, ANY16 S2, ANY16 S3, ANY16 D);
Argument Name
EN
S1
S2
S3
D
Remarks: The output value is controlled as described below.
When S3 (input value) < 0
......................S3 (input value) + S1 (negative bias value)
When S3 (input value) = 0 ...............................................0
When S3 (input value) > 0
....................... S3 (input value) + S1 (positive bias value)
Return Value
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.
ZONE_MD (X0, iData1, iData2, iData3, Result);
