I/O Variables Description

This table describes the input variables:

Inputs	Type	Comment
PTO_REF_IN	PTO_REF	Reference to the PTO channel. To be connected to the PTO_REF of the PTOSimple or the PTO_REF_OUT of the Administrative or Motion output pins function blocks.
Execute	BOOL	On rising edge, starts the function block execution. When FALSE, resets the outputs of the function block when its execution terminates.

Inputs

Type

Comment

PTO_REF_IN

Reference to the PTO channel.

To be connected to the PTO_REF of the PTOSimple or the PTO_REF_OUT of the Administrative or Motion output pins function blocks.

Execute

BOOL

On rising edge, starts the function block execution.

When FALSE, resets the outputs of the function block when its execution terminates.

This table describes the output variables:

Outputs	Type	Comment
PTO_REF_OUT	PTO_REF	Reference to the PTO channel. To be connected with the PTO_REF_IN input pin of the Administrative and Motion function blocks.
Done	BOOL	TRUE = indicates that PTODiag is valid. Function block execution is finished.
Busy	BOOL	TRUE = indicates that the function block execution is in progress.
Error	BOOL	TRUE = indicates that an error was detected. Function block execution is finished.
ErrID	PTOPWM_ERR_TYPE	When Error is TRUE: type of the detected error.
PTODiag	DWORD	When Done is TRUE: Diagnostic error code (see table below).

The following table is the encoding for the diagnostic variable PTODiag. For more detailed diagnostic information, see Detected Error Management.
