MC_StepReferenceFlyingRefPulse 4: Outputs

VAR_OUTPUT
    Done           : BOOL;
    Busy           : BOOL;
    Active         : BOOL;
    CommandAborted : BOOL;
    Error          : BOOL;
    ErrorID        : UDINT;
END_VAR

Name

Type

Description

Done

BOOL

Becomes TRUE, if the command was completed successfully.

Busy

BOOL

The Busy output becomes TRUE when the command is started with Execute and remains TRUE as long as the command is processed. If Busy becomes FALSE again, the function block is ready for a new order. At the same time one of the outputs, Done, CommandAborted or Error, is set.

Active

BOOL

Indicates that the command is executed.

CommandAborted

BOOL

Becomes TRUE, if the command could not be fully executed.

Error

BOOL

Becomes TRUE, as soon as an error occurs.

ErrorID

UDINT

If the error output is set, this parameter supplies the error number.
