5.8.1 E-NETx configuration
The five dip-switches are used to set the electronic drive Fieldbus address. To set the drive
address, enable the dip-switches in such a way that the binary number corresponds to the
required address. Bear in mind that the less important address corresponds to A0, and the most
important corresponds to A4. Dip-switches 3 and 4 (DSW1) are used to end the line (necessary to
prevent signal reflection on the line). If the device is the last connected module on the serial line,
dipswitches 3 and 4 must both be ON. For the other line modules, dipswitches 3 and 4 must both
be OFF (module not terminated).Refer to the user manual "Technical characteristics and E-NETx
connection” (for the E-NETx communication protocol) issued by HSD S.p.A. to have more
information on how to end the line correctly.
If dipswitches 3 and 4 are set differently (for example 3 ON and 4 OFF), the module
will not work correctly.
Logical address and E-NETx bus line termination
Access the Dipswitches of the E-NETx device board as described on page 46.
