Select USS protocol P780 = 2 P780 = 2 P790 / P800 = 2
Baud rate P783 = 1 to 13, corresponding to
300 to 187500 baud
P783 = 6 (9600 Bd) or
7 (19200 Bd)
The baud rate setting must be
identical for every node in bus
operation
P793 / P803 = 1 to 13,
corresponding to 300 to 187500
baud
No. of process data (PZD No.)
(applies to Receive and Send)
P781 = 0 to 16 P781 = 2 P791 / P801 = 0 to 16
PZD assignment for control word
and setpoints
(received process data)
All received process data are
taken to connectors and must be
wired up as required
If the control bits from the OP1S
are to be used:
Word 1 (connector K2001):
Wiring up of control bits
from OP1S, see Sec. 7.2.2
Word 2 (connector K2002):
Not used
All received process data are
taken to connectors and must be
wired up as required
No. of PKW P782 =
0: No PKW data
3 / 4: 3 / 4 PKW data words
127: Variable data length for
slave
→ master
P782 = 127 variable data length P792 / P802 =
0: No PKW data
3 / 4: 3 / 4 PKW data words
127: Variable data length for
slave
→ master
PZD assignment for actual
values
(transmitted process data)
Selection of transmitted values
via P784
Word 1: P784.i01=32
(stat. word 1 K0032)
Word 2: P784.i02=0
Selection of transmitted values
via P794 / P804
Node address P786 = 0 to 30 P786 = 0 to 30
Every node must have its own,
unique address for bus operation
P796 / P806 = 0 to 30
Telegram failure time P787 = 0.000 to 65.000s P787 = 0.000s P797 / P807 = 0.000 to 65.000s
Bus termination P785 = 0: Bus term. OFF
1: Bus term. ON
P785 = 0: Bus term. OFF
1: Bus term. ON
P795 / P805 =
0: Bus term. OFF
1: Bus term. ON
Bus / point-to-point
communication
RS232: Only point-to-point
operation possible
