1) Beginning with OS versions 3.x, only the transmission rate is automatically adapted when
"Autonegotiation On" (S2/3 ON) is set. The duplex mode must be set using switch S2/5.

Automatic adaptation of transmission rate (10/
100 MBit/s) and duplex mode if is Switch S2/3 is
ON.
4 100 MBit/s 10 MBit/s The switch position of switch is only relevant if
switch S2/3 (auto-negotiation) is OFF.

2) Beginning with OS versions 3.x, autonegotiation must be activated at the communication
partner (e.g. switch) if full duplex (S2/5 ON) is set on the F 8627X . Not observing these set-
tings can lead to communication problems.
Full duplex Half duplex The switch position of switch is only relevant if
switch S2/3 (auto-negotiation) is OFF.
Simultaneous sending and receiving if switch
S2/5 is ON.
Note on full-duplex operation:
In network topologies where hubs are used,
hubs must be replaced by full-duplex switches
(hubs are not full-duplex capable).
6 2 OPC server 0 Beginning with the F 8627X OS version 3.x, the
number of HIMA OPC servers (0 to 14) must be
set via switches. Switches S2/6-8 can be com-
bined by the user.
If HIPRO-S-DIRECT is not active the number of
HIMA OPC servers is four.
For determining the Node Ids and IP addresses
for the configuration of HIMA OPC server, see
Chapter 6.8.1.4 and Chapter 6.9.1.5.

Note Beginning with OS version 4.x, an F 8627X with the settings "Autone-
gotiation Off" (S2/3 OFF) and "full duplex" (S2/5 ON) may not operate
with a communication partner (e.g. switch) with Autonegotiation acti-
vated.
Since these settings are allowed for OS version V3.x and below, they
must be checked and, if necessary, adapted when upgrading to OS
version V4.x or higher. Not observing these settings can lead to com-
munication problems.
