Editing a Sequence Call in the Sequence Editor

To edit a sequence call, block-local sequence call, or connector in the Sequence Editor, proceed as follows:

1. Right-click a sequence call in the drawing area and select Edit from the context menu.

   The Sequence Editor opens.

2. From the Method/Process Name combo box, select the method/process for a normal sequence call.

   For a block-local sequence call, the name of its statement block is the only possible selection.

3. Do one of the following:

   • In the Sequence Number field, set the number of the sequence call.

   • Click Next free to set the next free number for the selected method/process.

     Note
     Next free is not available for connectors and block-local sequence calls.

4. In the Sequence Shift Offset field, enter the offset value for a sequence shift.
5. In the Sequence Step Size field, enter the step size for automatic determination of the sequence number.
6. Activate the Use Gaps option if gaps between existing numbers are to be taken into consideration in the automatic determination of sequence numbers.

7. Click OK.

   A check is carried out to see whether the set combination of number and – for sequence calls – process/method or statement block has already been assigned. If not, the combination is assigned to the sequence call or connector and displayed in the block diagram.

   Sequence Shift Offset, Sequence Step Size and Use Gaps are accepted in the Sequencing node of the ASCET option window.

The following rules apply for determining the number using Next free.

• Only whole multiples of the value in the Sequence Step Size field (corresponds to Sequence Step Size in the Sequencing node of the ASCET option window) are taken into consideration. If, for example, the value 5 is set, only the numbers 5, 10, 15, 20, ... are checked.

• If the Use Gaps option is activated, any gaps between existing sequence numbers are filled. The first condition still applies; gaps which are not whole multiples of the value in the Sequence Step Size field are not filled.

  If, e.g., the numbers 1–3, 5–9 and 11 have already been assigned, and 5 has been specified in the Sequence Step Size field, 10 is assigned, not 4.

  Note
  The system saves the sequence number last assigned. Gaps below this number are not filled! When you leave the editor or reset one (Resetting an Individual Sequence Call) or several sequence calls (Resetting Several Sequence Calls), the number saved is reset, automatic numbering starts again at 1.

• If the Use Gaps option is not activated, a search is carried out for the next whole multiple of the value in the Sequence Step Size field after the highest available number.

  In the above example (1–3, 5–9 and 11 assigned), 15 is assigned.
