Device Selection: Procedure

Device selection can be performed for the entire project or a selection of devices. Device selection can be called up from different places:

Depending on where the device selection was called up, the following different selection sets are available:

When you select a device, the program first checks if the parts manager contains the same functions as the device. If not, the program checks whether there are general functions (e.g. turnkeys, general). If so, the device is offered. On the other hand, for a device with general functions, all devices are offered that have a functional template from the same group.

You can select a device based on the type number, order number, or part number. For each part selected, (electrical) characteristics, function groups, part group, protection variant, assembly, and product subgroup are taken from the part definition in the schematic. Possible accessory components of a part are displayed with it.

Furthermore, there is a tabular preview of the defined function templates. The necessary function templates (that is, those defined for the device via its functions) and those determined in the device definition are displayed.

Depending on the settings for device selection, it is checked whether existing function data (e.g. the connection point designations) are changed by a device selection. An icon shows whether the device's function definitions correspond to those of a device definition.

Notes:

Device selection for special functions

Functions that are only needed to define a device are handled separately in the device selection. This includes black boxes, PLC boxes, terminal strip definitions, plug definitions, cable definitions and shields.

If the device selection is carried out for a device that consists only of such functions and is otherwise empty. the device selection will display all parts that have at least the function templates for this function.

Multiple selection (block editing)

For multiple selection of elements, the behavior of the device or part selection changes according to whether they are started from the Properties <...> dialog or from the navigator:

The device selection is performed once for each main function selected.

Assignment of parts to devices

Devices can be represented by one or more components:

Different parts can be assigned to these devices:

Any combination of device and parts is possible. Module information is stored in the main function.

Assignment of modules

Modules can also be assigned using the device selection - in addition to individual parts or assemblies.

If a module is assigned to a "normal" main function, then the part number of the module is stored there.

If a module is assigned to a black box, however, then EPLAN looks at all the main and auxiliary functions contained in the marked black box and in all black boxes cross-referenced with it, and assigns the parts of the module to the appropriate main functions. The data from the function templates is also transferred to the functions contained in the black box.

If an assembly is assigned to the black box instead of a module, then the parts of the assembly are stored in the black box and are not distributed among the functions it contains.
