Assigning / Changing Part Numbers

An EPLAN user recently asked me how to change or assign a part number in EPLAN and I thought that I would share my response with you as it may help others.  There are MANY different ways to accomplish this task in EPLAN and the best answer for you will always depend on your particular use case. Get to know all the different methods and then the best solution for your particular instance will reveal itself.

As I said there are MANY different ways to accomplish this task in EPLAN, I will discuss only the most common methods here..my coffee is almost gone.

Assign/Change a part number using Device Selection
EPLAN has a special tool built in that makes it simple to either assign a part number or to exchange a part number. This tool uses information assigned in the parts manager to identify the type of device you have selected and then to filter the parts database to similar items, in particular the product group and the function definition. This means that when you select something like a circuit breaker symbol and then use device selection, EPLAN will filter the parts database and only show you part numbers for circuit breakers, this makes it very easy to find the part number that you want to assign to a symbol.

  • Select a symbol in your design.
  • Double left mouse click to bring up the device properties
  • At the bottom left of the dialog, select [Device Selection]
  • In the main parts window, right click and select Configure
  • Representation to configure the display with the part data that is of interest to you.
  • Select the desired part number to assign
  • Select the BLUE ARROW to assign the part number
  • [OK] to accept the changes
  •  

Exchange (Change) Part Numbers
For the typical user changing a part number that has been assigned to a device can be accomplished with several tools built into EPLAN.

At the main menu select: Project Data > Parts/ Devices > Bill of materials navigator. Also note that if you have more than one project open you will need to select the project of interest in the navigator.

You can view the part assignments using either the [TAB] view or the [List] view.

The Bill of materials navigator will present to you a list of all the parts in the current project parts database.

  • Find and select the part number that you wish to change, the tool can “exchange” all instances of a particular part or only the ones that you select.
  • Select a part in the tree view.
  • Double click on the item to expand the selection. As you do you will see the current DT in use (if assigned) and one or more instances.
  • Right Click on the desired part, Select “exchange part” from the menu
  • Select a new part number from the system parts manager
  • [OK] to overwrite the updated part info to the item

Exchange (Change) Several Part Numbers

You can also select a part number in the navigator and exchange all current instances of the part in your project.

  • Find and select the part number that you wish to change, the tool can “exchange” all instances of a particular part or only the ones that you select.
  • Select a part in the tree view.
  • Find the parent part number OR the parent DT that you wish to exchange in the navigator. 
  • Right Click and select “exchange part” from the menu
  • Select a new part number from the system parts manager
  • [OK] to overwrite the updated part info to the item

At the parent DT level the graphical preview can or will display the image of the part that is or was assigned in the parts manager database when this part was added.

I hope that helped you..
