Siemens SIMATIC TIWAY 1 Manual De Usuario

The Standalone Network Manager (SANM) mode is configured completely with
dipswitch settings. The definition for some of the dipswitch positions is different
for this operating mode as shown in Figure 2–12. The SANM mode is selected by
defining the host command timeout as zero by setting Positions 9 and 10 of
Dipswitch 1 down. The other positions of Dipswitch 1 define the TIWAY I
network parameters.
