2.4 Setting the PROFIBUS Address
The station address of GW-7557 can be set by using 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 5
shows
three examples of setting the station address by using the DIP switch. The DIP
switches are accessed by opening the modules housing (
Figure 11)
.
Table 6
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.
