Volume 7
About this User’s Manual: Volume 7 of the Uni-Probe LB 490 User’s Manual is a supplement to
the standard documentation of the level measuring system Uni-
Probe LB 490 and includes instructions for operation of the system
with FOUNDATION
™
Fieldbus Interface.
This documentation assumes that the reader is familiar with the
software for operation of the FOUNDATION
™
Fieldbus and its basic
operation. Since different programs can be used, no menus or dia-
logs will be used in this manual, only the function block and param-
eter names are listed. These and the basic procedures are identical
in all programs for the FOUNDATION
™
Fieldbus.
We recommend that you always use Volume 7 in connection with
the standard version of the Uni-Probe LB 490 User’s Manual (ID no.
38477BA2).
Explanation of terms: Record
A record includes a set of several parameters. The record itself
does not include any value, but only the subordinate parameters.
Send the entries to the Uni-Probe
This sentence comes up often in this documentation. It means that
the entries made so far have to be sent to the Uni-Probe to become
effective. For example, in the NI-FBUS Configurator you have to
click on the “Write Changes” button.
