Automatic wire-numbering

Previous pageReturn to chapter overviewNext page

The automatic wire-numbering is way simpler to use than the manual one.

 

After you have set the project parameters in a suitable way, which you often do once and for all, you perform wire-numbering in the wire list of Dynamic OnLine I with a simple click. You can also use the Report Generator to create wire lists, where the same wire-numbers can be found.

 

Different kinds of wires can be numbered with separate numbering series. Wire-numbering in different cabinets can be separated from each other or be done together. It is up to you to choose what is most suitable for you!

 

The main principle is that cadett ELSA distinguishes between four types of wire connections.

 

Connection types for wires

Connection type

Description

1

Connections within a device (between two connection points on the same device)

 

2

Connections between two devices

 

3

Connections between devices and terminals

 

4

Connections between two terminals

 

 

You can define three separate numbering series, which you can use for the four connection types that are listed above. Of course, two or more connection types can use the same series, if you want them to. For instance, they can all use the same series.

 

Connections to or from terminals can use the terminal number as wire-number instead of a number from a series. This, however, leads to two problems, which both have their solutions:

 

1.Two wires in the same sub-node (wire-chain) can in this way get the same wire-number. This is a violation of the basic rules for wire-numbering, as stated in the previous.

 

The solution to this problem in cadett ELSA is to use a suffix. If two wires in the same wire-chain have for instance wire-number 100, the first one can be named 100, while the second one becomes 100.1.

 

2.A wire between two terminals could be given either of two different numbers. Which of the two should be chosen as wire-number?

 
The answer to that question in cadett ELSA, is to use both. A wire between terminals 1 and 3 would hence get 1-3 as wire-number.

 

All handling of the numbering series, how they are used and the rules all this is controlled by, is defined by project parameters.

 

The project parameters that are relevant for the purpose are described in a general manner here. References to more detailed descriptions found in the documentation of the Project module are also provided.

 

The first project parameter which is relevant here is Activation of Connection lists and wire numbering. This parameter must be activated for the wire-numbering to work. However, please note that if you are using cadett ELSA LT or cadett ELSA Basic, this menu item is always inactive. It is in other words not possible to do an automatic wire-numbering in those products.

 

Other important project parameters, which control the wire-numbering, are found in the Connections 2 (wires) tab.

 

Some of the most relevant project parameters in that tab are described in the table below.

 

Project parameter

Description

Default dimension

This is the default dimension for wires. If nothing else is defined in the circuit diagram by either a property symbol or a wire-number symbol, the dimension is assumed to be whatever is specified here.

 

Default colour

In a similar way, this is the default colour for wires. If nothing else is defined in the circuit diagram, in the same manner as with the dimension, the colour is assumed to be the one specified here.

 

Overall sorting

In which order should the connection points be connected and numbered, within each wire-chain (electrical sub-node)?

 

You can choose between the following alternatives:

 

None

Plant

Location

Plant and location

 

The order is controlled by multiple criteria of which this parameter is the most comprehensive. The most common setting is probably Location. This means that the wiring is primarily kept together within each location. The assumption is that the location is equivalent with a cabinet, a section of a cabinet, or something equivalent to that.

 

If you use the function aspect (Plant) in a way that makes it in some way suitable to take into consideration when calculating the wiring sequence, you can choose Plant or Plant and location (the combination of plant and location).

 

Sub-sorting controlled by cabinet layout

 

Shall the connection generation take a possible cabinet layout into consideration or not?

 

You can choose whether this function should be active or inactive. Active is recommended. This works even if there is no cabinet layout available.

 

If this function is active, the sorting within the range that is defined by the previous parameter (for instance a cabinet), is done according to the cabinet layout. In most cases that results in a better, more optimised, wiring.

 

Restart of wire numbering (numbering range)

 

 

You can choose between the following options:

 

All through (no restart)

According to "Overall sorting" (specified above)

Level 1

Level 2

Level 3

 

All through means that the wire-numbering is done throughout the project. This results in wire-numbers that are unique within the entire project.

 

According to "Overall sorting" means that the numbering will restart in accordance with the Overall sorting project parameter, which is described above. If that parameter for instance is set to Location, the numbering will restart for each cabinet (each location designation). The wire-numbering will, in other words, start from the beginning in every cabinet, independent of other cabinets.

 

Level refers to a separation of locations or plants in levels, as defined in the Item designation 1 tab of the project parameters, in the Multiple level item designations section.

 

Wire numbering

This section is divided into four parts after the four different types of wires that cadett ELSA differs between:

 

Type 1 – wires between two connection points within the same device

Type 2 – wires between two devices

Type 3 – wires between devices and terminals

Type 4 – wires between two terminals

 

For each connection type, you can decide how the wires of that type should be numbered.

 

You have the following options for each one of them:

 

None

Series 1

Series 2

Series 3

Terminal number (only for connection type 3 and 4)

 

None means that the corresponding wires wont get any wire-numbers.

 

Series 1 means that the wire-numbering will be made using numbering series 1, which is defined separately.

 

Series 2 is the corresponding for numbering series 2 and Series 3 for numbering series 3.

 

Terminal number means that a wire will be given a wire-number which is equal to the terminal number of the terminal to which the wire is connected. If, for instance, a wire is connected to –X1:100, it will get  number 100. For a wire between two terminals, both terminal numbers will be used, with a hyphen in between. If, for instance, a wire that connects –X1:100 with –X1:105 will get 100-105 as wire-number.

 

Do not number wires to devices with the following component type letter codes

 

This menu item can be used to exclude wires to certain component types from wire-numbering.

 

Example:

 

Certain PLC’s have molded connection cables. It might be a good idea not to use wire-numbers for the cores of such cables.

 

Connections directly to a motor are in many cases not wire-numbered, when the safety breaker is mounted directly on the motor, without any wires in between.

 

Here you can enter that you do not want to wire-number connections to motors by adding the letter M to this parameter ("M" is the component type letter code for motors). Generally, component type letter codes may have as many as five characters. Therefore, to include all variants of motors, you could specify M* instead, which would include all component type letter codes starting with the letter M.

 

If you also wish to exclude PLC’s with component type letter codes that starts with the letter D, you could specify M*,D*.

 

Numbering series for wires

You can define three different counting number series. For each one of them, you can specify a start value with a prefix and a step value.

 

At Start value, you enter the first wire-number in the series, for instance 01. 0 will then be seen as a prefix and 1 as the start value. This means that the numbering will be 01, 02, …, 08, 09, 010, 011, … 099, 0100, 0101 and so forth, if you have chosen a step value of 1. The first character is handled as a prefix, and the rest is regarded as a start value.

 

Suffix to separate identical numbers in the same node

As already stated, it is possible to number wires from terminals with the terminal number as wire-number. This is often both good and practical. It can, however, lead to problems. Two or more wires in the same node can then get the same wire-number.

 
If this parameter is active, that problem is solved using a suffix. Therefore, activating this parameter is strongly recommended. Otherwise, you will end up with an ambiguous numbering, which in turn will lead to other problems, like preventing a complete revision analysis.

 

Separator for suffix

The suffix, which is added to achieve unique wire-numbers within the same wire-chains, is separated from the original wire-number with a separator character. Here, you specify which character that should be. A commonly used separator character for that is the dot (“.”).

 

Example:        100, 100.1, 100.2 and so forth.
