5.2 Configuration of Device Address
The address of a PROFIBUS-PA device must always be set. Without a correctly set
address, the device will not be recognized by the control system. Valid device
address numbers range from 0...126. In a PROFIBUS-PA network, the address must
only be assigned once. All devices are delivered from the factory with the default
address 126. This address can be used for testing the device and for connecting the
device to a running PROFIBUS-PA network. After that the address must be changed
in order to connect with further devices. The configuration of the device address for a
Prowirl 77 can be done either with the help of an operating program (DP master
Class II, e.g. Commuwin II) or locally by using DIP switches which can be reached by
unscrewing the front cover.
Configuration of address mode
DIP switch No. 8: OFF = Addressing via the bus system
ON = Addressing via DIP switches No. 1...7 at the device
(see Fig. 13)
Configuration of application (fluid)
DIP switch No. 10: OFF = Application is configured via bus system
ON = Application is configured via DIP switch No. 9
(No. 9: OFF = liquid or No. 9: ON = gas/steam)
