Devices

Often, you have particular specifications from which it can be deduced as to which devices are used in a project and how often they are used. If you work with predefined devices, you can select such a device and place it.

Two methods of working are possible with EPLAN:

In the device-oriented approach, you first define specific devices. Subsequently you select such a device – using the device selection – and place the corresponding symbol or macro in the project. The existing functions of a particular device are integrated into the project from the very beginning. You can insert the entire logic from the parts data into the project in a single step. We call this manner of working the (device-oriented) engineering approach.

In the symbol-oriented approach, the functions (symbols) are first placed in the project and subsequently the device selection is performed.

Both methods can also be combined.

Working in this engineering approach involves the following steps:

Predefining devices
Working with the Navigators
Working with predefined (or imported) device lists
Use existing functions
Synchronizing the projected with the predefined devices

Devices allow the following working steps:

Schematics can be drawn via part selection.
You can first select the devices and add these to a list from which you then place the devices.
Devices can be tested and locked from being changed.
Devices can be graphically represented using several symbols.
Devices can be exchanged.
Several devices can be combined into a module.
Devices and modules can be copied from one project to another.
Parts can exist in a project without a graphical representation (and without a DT), and can be reused.
