Device Terminal Details Catalog Structure ( CATXxx.DBF )
| Fieldname | Default width | Description |
|---|---|---|
| CATX_REF | 25 |
User defined label identifying the device terminal arrangement of the record. If this is left blank then the MFG and CATNO values must be specified to identify the terminal arrangement. The same CATX_REF values should be used in the CATDxx databases to link the devices to their terminal arrangements. |
| CATNO | 50 |
Device part number. (required if CATX_REF is not used) |
| MFG | 5 |
(required if CATX_REF is not used) |
| CATDESC | 59 |
Text description of the component. |
| LINK_LEN | 10 |
Length of a link wire between any two terminals on this device. (This field is currently unused). |
| TERM_1 | 40 |
Terminal detail field for the first terminal field in this catalog. Each terminal field contains comma-separated data for one of the terminals on the device with the part number above. The comma-separated data is detailed below this table. |
| TERM_2 | 40 |
Second terminal detail field. |
| TERM_... | 40 |
... |
| TERM_X | 40 |
Terminal detail field for the last terminal field in this catalog. The number of fields is user definable when making a CATX catalog file. |
Comma separated terminal data
The terminal data for each terminal on a device contains TAG, PREFERRED DIRECTION, WIRE COUNT and SPATIAL POSITION data. This data is in the format:
TAG , DIRECTION , WIRECOUNT , SPATIAL_X , SPATIAL_Y , SPATIAL_Z
TAG:
The identifying tag of the terminal used on circuit diagrams. e.g. "12" e.g.2 "A2".
Preferred Direction:
A single letter denoting the direction of preferred wiring to a duct. If 2 ducts are close enough to connect to this device terminal then the duct in the preferred direction will be used.
If the device is rotated in 3D space, the preferred directions are rotated with the device EXCEPT for G and F type terminals, which always reference to ducts BELOW or ABOVE the terminal.
The letters are:
T Prefer connection to top of device.
B Prefer connection to base of device.
L Prefer connection to left of device.
R Prefer connection to right of device.
F Prefer connection to front of device.
K Prefer connection to back of device.
G Connect to closest ZONECLASS = 6 duct below the terminal.
F Connect to closest ZONECLASS = 6 duct above the terminal.
Wire Count:
The MAXIMUM number of wires which may be terminated on this terminal. This is only used when wire LOOP optimisation is run to re-arrange terminal order.
Spatial Positions:
This is the X, Y and Z offset from the front lower left corner of the device, used for wire length calculations. This should be entered with units attached. e.g. "10cm". The position is always relative to a co-ordinate system aligned with the device.
Example:
001,T, 2, 5cm,4cm,6cm
Tag is: 001
Preferred direction is: TOP
Only 2 wires may be terminated at this terminal.
Offset from front, lower, left is: 5cm, 4cm, 6cm
'G' Type Terminals
A terminal with the 'G' character [for preferred direction] will connect to the closest duct, that has a zoneclass of "6", below the position of the terminal.
Below the terminal is defined as: In the negative direction in the Z-axis, in the world co-ordinate system.
Ducts that are intended to carry wires connecting to 'G' type terminals must have "6" entered into their zoneclass field.
'F' Type Terminals
A terminal with the 'F' character [for preferred direction] will connect to the closest duct, that has a zoneclass of "6", above the position of the terminal.
Above the terminal is defined as: In the positive direction in the Z-axis, in the world co-ordinate system.
Ducts that are intended to carry wires connecting to 'F' type terminals must have "6" entered into their zoneclass field.
