    The folder structure

    Every add-on has the same folder structure.The folder names are marked with <> when names are optional and can be changed by the addon developer.

    Note:

    This add-on folder can exist anywhere on the disk!

    An add-on always consists of the same folder structure, which basically looks like this:

    <Add-on>

                  <Add-on version>

                                BIN          Here, all binaries of the add-on are installed.

                                CFG          Here, all XMLfiles and the install.xmlare installed. The Install.xmlfile is the base data. The names of the folders are listed in the install.xml for copying the data to the EPLAN base data

                  <Images>                                      

                  <Scripts>

                  <XML>

                  <…>

    The files

    The most important file is the install.xml. It contains all the information about the add-on and the EPLAN version.

    The install.xml

    This paragraph shows an install.xmlfile example, which is created with the EplAddonUtility.exe.

    Tip:

    For further information, about how to create an add-on with the EplAddonUtility.exe and which terms and conditions you should follow, see the EplAddonUtility documentation.

    Information about the settings

    ·      ApplicationModifier:

    The identifier for this add-on. This has to be a unique name without blanks and dots

    ·      XMLPath:

    Location of CFG-folder of add-on

    ·      Version:

    This is the version number of the add-on.

    ·      MainVersion:

    One sub-node belongs to one EPLAN version. The node Basic contains the licence information and version information for EPLAN Electric P8.

    -Licences

    Add-on program validity. All of the licences must be available, so this add-on can be registered for this main version

    -Versions

    Add-on version validity. Oneof the version numbers must match the EPLAN version number, so this add-on can be registered. The version number can contain a * as a wildcard. This is interpreted as “any”.

    The API add-ins

    It is possible to list the API add-ins in an XML file with any name.

    XML
    Copy Code
    <Settings format="2">
      <CAT name="STATION">
        <MOD name="AF">
          <LEV1 name="ApiModules">
            <Setting name="MyAddon" type="string" info="">
              <Val>Eplan.EplAddin.Addin_2_8</Val>
            </Setting>
          </LEV1>
        </MOD>
      </CAT>
    </Settings>
    

    All API Modules in the setting “ApiModules” are registered and loaded.

    When an API add-in has a linked dll in the add-on binary path, the dll should be registered as a reference. This is the list in ”API reference”. Then EPLAN will always be able to resolve this API add-in.

    The Scripts

    When a script should be registered when the addon is registered, one XML file has to have a content similar to this:

    XML
    Copy Code
    <Settings format="2">
      <CAT name="STATION">
        <MOD name="AF">
          <LEV1 name="Scripts">
            <Setting name="MyAddon" type="string" info="">
              <Val>BIN\myScript.cs</Val>
            </Setting>
          </LEV1>
        </MOD>
      </CAT>
    </Settings>
    

    The script file location is either an absolute path or a relative one. The relative path is calculated from the add-on path, where the BINand the CFGfolder is in.

    Toolbars

    Since version 2.4.x it is possible to import a toolbar when the add-on is registered.

    XML
    Copy Code
    <Settings format="2">
      <CAT name="STATION">
        <MOD name="AF">
          <LEV1 name="Toolbars">
            <Setting name="MyAddon" type="string" info="">
              <Val>CFG\myToolbar.xml</Val>
            </Setting>
          </LEV1>
        </MOD>
      </CAT>
    </Settings>
    

     

    The toolbar is imported from the XML file when the add-on is registered. When the user changes his workspace, this toolbar is removed again.

    Unregistering the add-on will remove the toolbar.
