Components

Each record in the tag tables of the project database represents a component. Each component can be linked to a ratings record. Each component can be linked to other components in the database. Creating components, editing their ratings and linking them to other components are the fundamental operations of the Cable Scheduler interface.

Component Types

Each component in the project database has an associated type. This type is determined when the component is created and cannot be changed

Components in the project database can contain (be the parent of) other components. This behaviour is achieved by creating a relational link between the components within the database structure. The types of components a given component can contain depend on the type of that component. The purpose of each component type and the types of components they can contain are discussed below.

Areas

An area component represents a physical location in which other components can exist. Areas can contain enclosures or devices.

The value used in the Component_Type column in the Tag_Tags table is "Area".

Enclosures

An enclosure component represents a physical container for electrical and electronic devices, for example a switch panel etc. Enclosures can be contained in areas. Enclosures can contain devices and terminal strips.

The value used in the Component_Type column in the Tag_Tags table is "Enclosure".

Devices

Devices represent any electrical or electronic device, for example a relay or PLC etc. Devices can be contained in enclosures, and can contain terminals.

The value used in the Component_Type column in the Tag_Tags table is "Device".

Terminal Strips

Terminal strips are in reality a group of discrete terminals. Inside Cable Scheduler a terminal strip object is used to refer to each group of terminals as one object: namely a terminal strip. Terminal strips can only be contained in enclosures, and can contain terminals.

The value used in the Component_Type column in the Tag_Tags table is "Terminal Strip".

Terminals

Terminals represent an electrical connection point. They should always be contained in an instrument, device or terminal strip. Terminals cannot contain any other components. Terminals can be connected cores or conductors of cables.

The value used in the Component_Type column in the Tag_Tags table is "Terminal".

Terminal Groups

A terminal group represents a single I/O channel on a PLC card or a user-defined grouping of terminals on a device. Terminal groups are contained in PLC cards or devices. A terminal group links to the terminals that are functionally part of that group. A PLC card or device can contain multiple terminal groups. A common terminal of a PLC card or device can appear in more than one terminal group.

Terminal Groups are stored in the "TerminalGroup_Terminal Groups" table, not the Tag_Tags table, and the terminal groups table does not have a Component_Type column. The value to use for the component type if you are importing a terminal group is "Terminal Group".

Wires

Wires represent single conductors, and are used to make an electrical connection between two terminals, one for each end of the wire. Wires should only connect the terminals of instruments, devices and terminal strips that reside in the same enclosure. Wires are not contained by and cannot contain any component.

The value used in the Component_Type column in the Tag_Tags table is "Wire".

Cables

Cables represent multiple-core conductors. Cables are not contained by any other component. Cables can contain cores (conductors) which connect the terminals of instruments, devices and terminal strips.

All of the components, to which each core or conductor of a single cable is connected, must be contained in no more than two distinct enclosures.

Cables can be directly connected to devices and enclosures without the need to connect the cores. This can be useful in the planning stages of your project or for cable routing in Cable scheduler.

The value used in the Component_Type column in the Tag_Tags table is "Cable".

Cores / Conductors

Cores represent the individual conductors contained in a cable. Cores can make an electrical connection between two terminals, one for each end of the core. Cores should always be contained in a cable. Cores cannot contain any component.

The value used in the Component_Type column in the Tag_Tags table is "Core".

Raceway Segments

Raceway segments are individual segments of tray, conduits, trench or duct that have been created in your raceway model within Paneldes. They have properties that include their type and shape and also their capacity for cable carrying and power level. Raceway segments are only really useful inside Cable Scheduler creating raceway groups used for guiding cables and for creating raceway groups used which are whole routes.

Raceway segments are stored in the "RacewaySegment_Raceway Segments" table, not the Tag_Tags table, and the raceway segments table does not have a Component_Type column. The value to use for the component type if you are importing a raceway segment is "Raceway Segment".

Raceway Groups

Raceway groups are either complete routes (lists of segments) or a set of raceway segments used to guide a cable when its route is being created.

Raceway groups are stored in the "RacewayGroup_Raceway Groups" table, not the Tag_Tags table, and the raceway groups table does not have a Component_Type column. The value to use for the component type if you are importing a raceway group is "Raceway Group".
