SerializeIn

 Function A function calculates a result according to the current value of its inputs. A function has no internal data and is not linked to declared instances. - Extract the value of a variable from a binary frame In networking dialect, a message is called a frame..

Inputs

Input	Data Type	Range	Unit	Default	Description
En	BOOL	0, 1	N/A	No default	Execute the function.
Frame[ ]	USINT	0,+65535	N/A	N/A	Source buffer. Must be an array.
Data	ANY(*)	No range	N/A	No default	Destination variable to be copied.
Pos	DINT	0,+65535	N/A	N/A	Position Position means a point in space which is described by different coordinates. Depending on the used system and transformation it can consist of a maximum of six dimensions (coordinates).This means three Cartesian coordinates in space and coordinates for the orientation. In ACS there can be even more than six coordinates. If the same position is described in different coordinate systems the values of the coordinates are different. in the source buffer.
BigEndian	BOOL	0, 1	N/A	No default	TRUE if the frame is encoded Generates an output signal directly proportional to the movement of the motor shaft. This signal is fed into the control circuitry to control the shaft position and speed. The most common types are: Incremental/Serial encoders, Hall effect sensors, Resolvers, Tachometer Generators See: Optical encoders. with Big Endian format.

(*) DATA cannot be a STRING.

Outputs

Output	Data Type	Range	Unit	Description
OK	BOOL		N/A	Returns TRUE when the function successfully executes. See Pipe Network - General Rules.
NextPos	DINT		N/A	Position in the source buffer after the copied data. 0 (zero) in case of error (e.g., invalid position or buffer size).

Remarks

• Used to extract data from a communication frame in binary format.
• This function cannot be used to serialize STRING variables.
• The DATA input must be directly The orientation components of a vector in space. connected to a variable.
  • It cannot be a constant or complex expression.
  • This variable is forced with the extracted value.
• The FRAME input must fit the input position and data size.
  • If the value cannot be safely extracted, the function returns 0 (zero).
• The function returns the position in the source frame after the extracted data.
  • The return value can be used as a position for the next serialization.

This function extracts these number of bytes from the source frame:

Bytes	Description
1 byte	BOOL, BYTE, SINT, and USINT variables.
2 bytes	INT, UINT, and WORD variables.
4 bytes	DINT, DWORD, REAL, and UDINT variables.
8 bytes	LINT and LREAL variables.

FBD Language Example

FFLD Language Example

• In the FFLD Language, the operation is executed only if the input rung (EN) is TRUE.
  • The output rung (ENO) keeps the same value as the input rung.

IL Language Example

Not available.

ST Language Example

Q := SERIALIZEIN (FRAME, DATA, POS, BIGENDIAN);
