Project Module > Project parameters (detailed description) > Connections 2 (wires) > Wire numbering exceptions > Do not number wires to devices with the following component types

Wires to certain types of devices can under some circumstances not be suitable for wire numbering. That could for instance be a connection to a PLC, implemented as an embedded cable, which therefore is in fact not a wire at all.

In this parameter, you can specify a number of component type letter codes. All wires connected to devices with those letter codes, will be excluded from wire-numbering. Please note that this refers to the component type letter code that is specified in the main symbol, not the one that is extracted from the item designation. (In many cases that can be identical, but it does not have to).

Component type letter codes in most cases consist of one letter only, as is the case with all standard symbols in the IEC1082 symbol library, but up to five letters are supported by cadett ELSA. It is therefore possible to use so-called wild-cards when specifying letter codes in this parameter.

You can specify several component type letter codes with commas between them.

Do not number wires to devices with the following component type letter codes	Result
D,M	Wires to devices with component type letter codes D and M (normally PLC's and motors) will not get wire-numbers.
D,M	Wires to devices with component type letter codes that begin with letters D or M will not get wire-numbers. In most cases, that will give the same result as the previous choice, but component type letter codes consisting of several letters will be supported, as opposed to the previous example.

Result

D,M

Wires to devices with component type letter codes D and M (normally PLC's and motors) will not get wire-numbers.

D*,M*

Wires to devices with component type letter codes that begin with letters D or M will not get wire-numbers. In most cases, that will give the same result as the previous choice, but component type letter codes consisting of several letters will be supported, as opposed to the previous example.

Please note that wires without wire-numbers may constitute a problem in further management of a project, like when working with revisions. Using this feature is therefore not recommended in most cases.
