Setting the PROFIBUS interface

Interfaces and diagnostic LED
See Chapter PROFIBUS connection (Page 162).
Note
A teleservice adapter can be connected to the PROFIBUS interface (X126) for remote
diagnostics purposes.
Setting the PROFIBUS address
The PROFIBUS address is set at p0918.
The factory setting is 126.
Each PROFIBUS address in a PROFIBUS line can only be assigned once. When several
Control Units are connected to a PROFIBUS line, you set the addresses differently than the
factory setting.
The PROFIBUS address can be changed
● Using the BOP20
● Using STARTER
You must switch to DO 1 (CU) to change the bus address using the BOP. Access level
p0003 = 3 is required to change p0918.
When using the STARTER commissioning tool, make sure that the bus address p0918 in the
offline project matches the online value. If this is not the case, the value is overwritten at the
next upload or download.
The PROFIBUS address must be saved in a non-volatile way using the "Copy RAM to ROM"
function.
The change made to the bus address takes effect after POWER ON.
