Dialog Number terminals / pins

In this dialog you specify the settings for the terminal designations or pin designations. When numbering terminals the Number terminals dialog will open, and when numbering pins the Number pins dialog will open. All terminals / pins are given a unique designation, which can consist of alphanumeric or just numeric elements.

Overview of the main dialog elements:

Scheme:

You can choose the numbering scheme from this drop-down list.

Click [...] to open the dialog Settings: Numbering dialog. In this dialog, you can edit an existing scheme or create a new scheme.

Sequence:

Use the drop-down list to define the sequence for numbering:

Extent:

Use the drop-down list to define the scope of numbering:


Group box Numeric settings

Start value:

Here you enter the start value for numbering terminals / pins.

Increment:

Here you enter the increment between each terminal / pin. If, for example, the increment "5" is specified, the terminals / pins will automatically be numbered 1, 6, 11, etc.

The number of places is determined by the online numbering format (Options > Settings > Projects > "Project name" > Devices > Numbering (online)).

Prefix / suffix:

The prefix comes before the numbering, the suffix comes after the numbering. Enter the appropriate characters here.


Group box Non-floating terminals / pins

PE terminals / pins ... SH terminals / pins:

In these fields you specify the numbering settings for PE / PEN, N, and SH terminals or pins. Settings are specified separately for the potential types PE / PEN, N and SH. The following options are available:


Multiple terminals:

Use the drop-down list to specify how multiple terminals should be numbered:

Tip:

If multiple terminals have different preceding signs (e.g., 1, +1, -1) and you would like to give them the same number, select the "Keep alphabetical elements" option in the Terminals with alphabetical characters field.

Terminals with alphabetical characters:

Use the drop-down list to specify how terminals or pins with alphabetical elements in the designation should be numbered. The designation has alphabetical elements, if itb does not consist exclusively of numbers.

Allow change in sorting:

If this check box is activated, the sorting and thus the sequence of the terminals / pins within the terminal strip / plug can change during numbering, if the sort code of the terminals / pins is empty. Manually entered sort codes remain unchanged and are taken into consideration in the numbering sequence.

If the check box is deactivated, the sorting and thus the sequence of the terminals / pins within the terminal strip / plug is retained during numbering. To this purpose terminals / pins with an empty sort code automatically have a sort code assigned before numbering. Manually entered sort codes remain unchanged and are taken into consideration in the numbering sequence. The existing terminal / pin designation is used as the automatically determined sort code.

Only number marked ones:

If this check box is activated, only those terminals / pins whose designations begin with a "?" or whose designations are empty will be numbered.

Filling gaps:

This check box is available if the Only number marked ones option is activated.

If this check box is activated, existing designations within the terminal strip / plug are taken into consideration during numbering. Starting from the start value the first free designation is assigned to the first terminal (or first pin) marked with a "?". Subsequently, numbering is continued using the specified increment, with existing designations being skipped.

If the check box is deactivated, the existing designations are not taken into account during numbering. In this case multiple designations within the terminal strip / plug can occur.

Note:

If you number terminals in accordance with the "Device definition" or "Initiators" scheme, it is possible that all the terminal designations of the device or initiator are already being used. In this case the terminals for which no free designation is found are not numbered.

Also number those controlled by PLC:

If this check box is selected, terminals / pins controlled by PLCs will also be numbered.
