Device Symbol Attributes
The supplied device symbols have the set of attributes shown below.
NB: "(cat)" indicates an attribute can be loaded from the catalog.
Hydraulic symbols are provided in EDS as single line device symbols. Therefore hydraulic symbols also have the attributes shown below.
Device Attributes
| TAGNAME | visible | Tag of component (All devices must have a unique tagname) |
| TAGSUFX | visible | Suffix to attach to the TAGNAME in reports. |
| RATING1 | visible (cat) | User specified rating or AMPS rating |
| RATING2 | visible (cat) | User specified rating or VOLTS rating
|
| RATING3 | visible (cat) | User specified rating or OHMS/COLOR rating |
| RATING4 | visible (cat) | User specified rating or WATTS rating |
| REFERENCE | visible | Cross reference data is automatically loaded to this attribute. |
| TERMPRFX | visible (cat) | Prefix to attach to the terminal numbers in reports. |
| T1 | see below (cat) | First of a fixed array of six terminal numbers |
| T2 | see below (cat) | Second terminal number |
| T3 | see below (cat) | Third terminal number |
| T4 | see below (cat) | Fourth terminal number |
| T5 | see below (cat) | Fifth terminal number |
| T6 | see below (cat) | Sixth terminal number |
| CATDESC | invisible (cat) | Catalog description of component (e.g. "Low speed motor") |
| VISDESC | visible | Users visible description of component. (e.g. "Conveyor drive") |
| PNLNO | invisible | Panel enclosing device |
| MFG | invisible (cat) | Manufacturer code number ( from manufact.dbf ) |
| CATNO | invisible (cat) | Manufacturers part number (with any subcomponent code appended e.g.*0 or *M2 ) |
| USER_C1 | visible (cat) | User definable attribute, centre justified |
| USER_C2 | visible | User definable attribute, centre justified |
| RSTATUS | invisible (cat) | Control code for the "report status" e.g. Set to "No BOM" to exclude from the materials reports |
| VSN | invis. const. | Version number, for internal use only |
| LENGTH | invis. const. | Length of symbol |
| BUSW | invis. const. | Code specifying the terminal arrangement of the device |
Notes
-
Terminals T1..T6 are visible for schematic symbols and invisible for single line and hydraulic symbols.
-
The positioning of the six terminals is always in the same uniform pattern. On devices with fewer than 6 terminals, the extra terminal attributes should be ignored. If more than 6 terminals are required, the device should be broken down into logical sub-components. E.g. a relay can be broken down into: coil, NO contact, NC contact and 3 phase contacts.
-
Terminal layout and number is unimportant in single line and hydraulic symbols.
-
Elecdes provides fast methods of loading this attribute set upon inserting, via the Catalog, and when editing with the Global Editor.
-
All of the invisible attributes are used only in reporting. If you do not intend to create reports for your drawings, you will not need to enter data for invisible attributes.
