    automatic data rate detection by means of the autonegotiation and autocross function;
    the connection is made via the IE FC RJ45 Plug 180 with 180° cable outlet or via a standard patch cable.
  • Diagnostics LEDs for indicating the operational and communication status
• Simple installation;
  the CP 443-1 RNA is mounted on the S7-400 rack and connected to other modules by means of the backplane bus. There are no slot rules.
• The CP 443-1 RNA can be operated without a fan
• In combination with the IM 460/461, the CP 443-1 RNA can also be used in an expansion rack (ER)
