Editing Service Sequences
A FB type (typically but not always a service
interface function block (SIFB) type
) or an adapter
may have a service specification
, which may consist of a
number of service transactions
. Each service transaction
consists of zero or one input primitive
represented by an arrow
coming into one of the two interfaces of the service, followed by zero
or more output primitives
- If a service specification does not already exist, you can
add one with the Add Service item of
the root (top) node of the Element Navigator.
- You can Edit the names of the left and right service
interfaces by double-clicking on the service in the Element
Navigator. The figure below shows the result of replacing
DEVICE in the
- You can add a sequence to the service with the Add
Sequence item of the service's popup menu. This opens a dialog that lets you edit the new
sequence's name and comment.
- You can copy a sequence to the FBEditor's clipboard with the
Sequence item of the sequence's popup menu.
- You can paste a copy of a sequenceto the end of the service's
list of sequences with the Paste Sequence item of
the service's popup menu. This opens a dialog
that lets you edit the copied sequence's name and comment.
- You can rename a sequence by double-clicking on its
name in the Element Navigator.
- You can remove a sequence from the service by using the Delete
Sequence item of its popup menu in the Element Navigator.
- You can change the position of a sequence in the list
of sequences by using Drag
and Drop in the Element Navigator.
- You can add a transaction to a sequence in the Worksheet by using the Add
Transaction item in the Worksheet menu. This pops up a dialog as
shown below that lets you edit the interface, name and parameters of
the transaction's initial input primitive.
- Before leaving a table cell containing an edited value, be
sure to hit the Enter key to save the edited value.
- You can move a transaction up or down in a sequence by
selecting its input primitive, then using the Promote/Demote
function of the Rosette.
- Even if a transaction doesn't have an actual input
primitive, you can use a "dummy" input primitive for this purpose
and delete it when you're done editing the sequence.
- You can remove a transaction from a sequence by
deleting all its primitives (see below).
- You can add a primitive to a transaction by using the Add Output Primitive item of the popup
menu of any primitive in the transaction.
- You can move an output primitive up or down in a
transaction by selecting it, then using the Promote/Demote
function of the Rosette.
- An input primitive if present is always the first
one in a transaction, so it can't be moved up or down within the
transaction. That's why you can use it as a "handle" to move the
whole transaction up or down in the sequence.
- You can edit a primitive by double-clicking on its
- You can delete a primitive by using the Delete
item of its popup menu.
