Function Block A function block groups an algorithm and a set of private data. It has inputs and outputs. - Write binary data to a file.

Inputs

Input	Data Type	Range	Unit	Default	Description
Execute	BOOL	0, 1	N/A	No default	On the rising edge The transition of a digital signal from low to high. AKA: positive edge., write binary data to a file.
ID	UDINT	N/A	N/A	No default	The ID of the open file.
Frame In networking dialect, a message is called a frame.	USINT[ ]	N/A	N/A	No default	The array of binary data to write.
FrameSize	DINT	N/A	N/A	No default	Number of bytes to write from the Frame array.

Outputs

Output	Data Type	Description
Done	BOOL	If TRUE, the command completed successfully.
Error	BOOL	If TRUE, an error has occurred.
ErrorID	DINT	Indicates the error if Error output is TRUE. See the table in Search IndexFile and TCP/IP Function Block ErrorIDs.
