Socket Connection/Bus Termination/Line - BONFIGLIOLI Vectron ACTIVE CUBE Manual

4
The bus termination necessary on the bus line in the physically first and last subscrib-
er can be activated via corresponding circuits in the bus connection sockets (e.g. built
by Siemens).
Attention! The device(s) will only communicate with the master if
housing screen
Only admissible types are to be used for the bus socket. They must all be suited for
the 12 MBaud transmission rate.
This is, for example, type Profibus connector 12 MBAUD (6ES7 972-0BA11-0XA0)
from Siemens.
Only admissible types are to be used as a line for the Profibus (line type A).
This is, for example, type UNITRONIC-BUS L2/F.I.P. 1x2x0,64 from Lappkabel.
Attention! The line screen is to be connected to ground (PE) on both sides with
