9.7 PROFINET - Electrical connection
Figure 9.3: PROFINET - Electrical connection
Notice!
For contacting BUS IN and BUS OUT , we recommend our ready-made PROFINET cable
(see chapter 12.4.5 "Accessory ready-made cables for PROFINET").
To set up a PROFINET network with other participants with linear topology, the AMS 348 i
makes available another PROFINET-RT interface. The use of this interface drastically
reduces the cabling requirements, as only the first AMS 348
i requires a direct connection
to the switch, via which it can communicate with the host. All other AMS 348 i can be
connected in series to the first AMS 348 i , see figure 9.2.

For the connection of two AMS 348 i , the "KSS ET-M12-4A-M12-4A-P7-…" ready-made
cables are preferred, see table 12.4.5 "Accessory ready-made cables for PROFINET" on
page 116.
If you use user-configurable cables, note the following:
Notice!
The entire interconnection cable must be shielded. The shielding connection must be at the
same potential on both ends of the data line. This prevents potential compensating currents
over the shield and possible interference coupling by compensating currents. The signal lines
must be stranded in pairs.
Use CAT 5 cable for the connection.
