BUS OUT for the BCL 504
To set up the PROFIBUS with additional participants, the BCL 504
interface of type DP OUT - outgoing PROFIBUS DP.

Table 7.5:
Notice!
Ensure adequate shielding. The entire connection cable must be shielded and earthed. For
connecting DP IN and DP OUT, we recommend the ready-made PROFIBUS cables. See
"Accessory ready-made cables for bus connection" on page 189.
7.2.6
PROFIBUS termination
The last physical PROFIBUS participant must be terminated with a terminating resistor (see
"Accessory terminating resistor" on page 187) on the BUS OUT socket.
