X23 Htl/ Ttl Encoder Interface - Siemens SINAMICS S120 Equipment Manual

Control Units
6.2 Control Unit CU310 DP (PROFIBUS)
Note
A teleservice adapter can be connected to the PROFIBUS interface (X21) for remote
diagnosis purposes.
The power supply for the teleservice terminals 2 and 7 withstands a max. load and continued
short-circuit current of 150 mA.
PROFIBUS connector
At the first and last node (device) in a line, the terminating resistors must be switched-in in
order to ensure disturbance/noise-free communications.
The terminating resistors are activated in the connector.
The cable shield must be connected at both ends over large-surface area contacts.
