Socket Occupancy/Bus Termination/Line - BONFIGLIOLI ACTIVE Manual

The factory setting for the bus termination is OFF.
As an alternative, this is possible via corresponding circuits in the bus connection sock-
ets (e.g. made by Siemens).
Attention! It is absolutely necessary that only one of the two possibilities for the
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 on a

bus termination is used and the bus termination is only switched on with
the first and last subscriber. If not, operation of the Profibus is not pos-
sible.
If the bus termination is activated on an inverter (Profibus component or
bus socket), it is only correctly effective if the inverter has contact to
voltage. If not, the bus is not operation-capable.
