Address selectors

The addressing of the device can be done in two ways:
• The first and easiest way is to select the slave address using the rotary switches
that are located in front of the device, see Fig. 3.3.2.2.-1. Using this method, the
addresses 0-99 can be selected.
• If the rotary switches are set to address 0 (zero), the slave address can be set by
using the Profibus Configuration Tool (PCT), see Section 5.2. Starting PCT.

If no address is set, use the default address 125. Changing of the Profibus address
requires reboot of the gateway, that is through power off/on, or by changing to
application mode from the configuration mode using the A1 DIP switch, see Section
3.3.3.3. DIP switch configuration.
