15.4.3.3 Setting the bus address
This section describes the procedure to set bus address in the transmitter. Every device
in PROFIBUS PA must be assigned a unique address in the range of 0(0x00) to
126(0x7e). If it is not specified at the time of order, 126(0x7e) is the factory default. Do
not change to 0, 1 or 2 as these are used by master devices. There are two ways to set
bus address: by using communication tools or by hardware switch in device.

Address has to be set always between 0 and 126. If address switch is set to 127, the
address is automatically converted to 126. Hardware Address Switch change has to be
performed to reflect hardware switch status after powering off a device.
Software address
Device address can be set by PROFIBUS PA software tool if hardware address setting is
setting
not active. For further details, see applicable Function Manual (FM) A5E52748624.
