2.4 Setting the Profibus Address
The station address of GW-7552-B / GW-7552-M can be set by using either the
dip switch or by writing it directly to the EEPROM. The dip switch covers a range
from 0 to 255. The valid address range of a Profibus station spans from 0 to 126.
Table 8
shows three examples of setting the station address by using the dip
switch. The dip switches are accessed by opening the modules housing (
Figure
12)
.
Table 9
explains which address will be used by the module after power on, if
the dip switch address setting differs from the address stored in the EEPROM.

Dip Switch Setting
Description
0~125
1.
The address setting of the EEPROM is ignored.
2.
The address can not be set by the PROFIBUS configuration
tool.
126-254
1.
The address setting of the dip switch is ignored.
2.
If the address in the EEPROM is 126, the PROFIBUS
configuration tool can set a new address and save it to the
EEPROM.
255
1.
Slave address in the EEPROM is set to 126.
