Setting/Changing the PROFIBUS Address

The PROFIBUS address specifies the address under which the ET 200R distrib-
uted I/O device will be addressed by the DP master on PROFIBUS-DP.
The PROFIBUS address is set with the two decimal-coded, rotary switches in the
module.
Permissible PROFIBUS address
A PROFIBUS address can from 1 to 125.
Note
On delivery the PROFIBUS address is set to 0. This address must be changed
since it is reserved on the ET 200 distributed I/O system for the PG/PC.
Note
Due to the rotary switch only the addresses 1 to 99 can be set on the ET 200R
module. Valid address area: 3 to 99.
Setting the PROFIBUS address
The rotary switches for setting the PROFIBUS address are located inside the
module behind the metric PG covering caps on the front.
• Unscrew the covering cap and pull it off.
• Set the PROFIBUS address with the rotary switches (see figure 3–3). Set the
tens with the left-hand rotary switch and the ones with the right-hand rotary
switch (for direction of viewing see figure 3–2).
• Screw on the covering cap again. Make sure that the seals are positioned cor-
rectly!
