File Transfer Protocol (WebDAV)
WebDAV is an extension to the HTTPS protocol, giving access to the file system of the Anybus CompactCom. It replaces FTP that was the standard protocol when downloading files in earlier versions of Anybus CompactCom 40 EtherNet/IP IIoT Secure. Using a separate port number for WebDAV makes it possible to block WebDAV operations in routers and firewalls, but still letting web traffic through. WebDAV also offers the possibility to add the Anybus CompactCom as a network drive in Microsoft Windows.
The following port number is used for WebDAV communication:
TCP port 4443
WebDAV is enabled by default and can be disabled in the Ethernet Host Object (F9h), instance #1, attribute #25. If WebDAV is turned off, it is not possible to update the module firmware using File Download or Firmware Manager.
