The default port for the EPLAN P8 connection is port 80. If this port is already used by another service, the port for the EPLAN P8 connection must be changed.
The default port can be modified easily, and others can be added, via the program EplanUrlActivatoru.exe. The program is in the folder <EPLAN-Installation folder>\Bin\, for example, C:\Program Files (x86)\EPLAN\Platform\2.4.1\Bin\EplanUrlActivatoru.exe.
After the start, the following interface opens:
An entry can be edited by clicking it. The changes are applied after confirmation via [OK].
To change the ports via script, the Url keys of the following registry entries must be changed:
HKEY_LOCAL_MACHINE\SOFTWARE\ EPLAN HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\EPLAN
In addition to the registry entries, the URLs must be registered with netsh.
