Set instrument address

An address must be assigned to each Profibus PA instrument. The
approved addresses are between 0 and 126. Each address must
only be assigned once in the Profibus PA network. The sensor is only
recognized by the control system if the address is set correctly.
When the instrument is shipped, address 126 is set. This address can
be used to test the function of the instrument and to connect it to a
Profibus PA network. Then the address must be changed to integrate
additional instruments.
The address setting is carried out either via:
•
The address selection switch in the electronics compartment of
the instrument (address setting via hardware)
•
The display and adjustment module (address setting via software)
•
PACTware/DTM (address setting via software)
