MINITRAC 31 • Profibus PA

In the main menu point "Setup", the individual submenu points
should be selected one after the other and provided with the correct
parameters to ensure optimum adjustment of the measurement. The
procedure is described in the following.
Stick with the normal sequence of the menu items as closely as pos-
sible.
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 adjusted. This ad-
dress can be used for function test of the instrument and for con-
nection to a Profibus PA network. Then 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)
The hardware addressing is effective if an address <126 is set
with the address selection switches on the electronics module of
MINITRAC 31. Software addressing thus has no effect - only the set
hardware address applies.
The software addressing is only effective if address 126 or higher is
adjusted on the instrument with the address selection switches.
If a hardware address was adjusted (< 126), then the instrument
signals that the hardware address is active.
