I/O Variable Description

This table describes the input variables:

Input	Type	Comment
xExecute	BOOL	On detection of a rising edge, starts the function block execution. On detection of a falling edge, resets the outputs of the function block when any on-going execution terminates. NOTE: With the falling edge, the function continues until it concludes its execution and updates its outputs. The outputs are retained for one cycle and reset.
sCmd	STRING	USB script command syntax. Simultaneous command executions are not allowed: if a command is being executed from another function block or from USB script then the function block queues the command and does not execute it immediately. NOTE: A USB script executed from a USB memory key is considered as being executed until the USB key has been removed.

Input

Type

Comment

xExecute

BOOL

On detection of a rising edge, starts the function block execution.

On detection of a falling edge, resets the outputs of the function block when any on-going execution terminates.

NOTE: With the falling edge, the function continues until it concludes its execution and updates its outputs. The outputs are retained for one cycle and reset.

sCmd

STRING

USB script command syntax.

Simultaneous command executions are not allowed: if a command is being executed from another function block or from USB script then the function block queues the command and does not execute it immediately.

NOTE: A USB script executed from a USB memory key is considered as being executed until the USB key has been removed.

This table describes the output variables:

Output	Type	Comment
xDone	BOOL	TRUE indicates that the action is successfully completed.
xBusy	BOOL	TRUE indicates that the function block is running.
xError	BOOL	TRUE indicates error detection; the function block aborts the action.
eError	ExecuteScriptError	Indicates the type of the execute script detected error.

Example

This example describes how to execute an Upload script command:

VAR
EXEC_FLAG: BOOL;
ExecuteScript: ExecuteScript;
END_VAR
ExecuteScript(
xExecute:= EXEC_FLAG,
sCmd:= 'Upload "/usr/Syslog/*"',
xDone=> ,
xBusy=> ,
xError=> ,
eError=> );
