END_VAR

Name

Type

Description

Enabled

BOOL

The parameterized override is set.

Busy

BOOL

TRUE as soon as the command is started with Enable and as long as the command is processed. If "Busy" is FALSE, the function block is ready for a new order.

Error

BOOL

TRUE, if an error occurs.

ErrorID

UDINT

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