6.4.1 Setup
An address must be assigned to each Profibus PA instrument. Each
address may 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)
Hardware addressing
Hardware addressing is effective if an address less than 126 is set
with the address selection switches on the electronics module of
VEGAFLEX 82. In such case, software addressing has no effect - only
the set hardware address applies.
Software addressing
Software addressing is only effective if address 126 or higher is set
on the instrument with the address selection switches.
