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.
