user tag number. Later I/O modules
will be able to add their slot ID to their
TAG as shown on this screen. If so,
you do not need to otherwise identify
them. It is this tag number that is used
to bind an I/O Module to an Analyzer
module. The user tag number can be
set as shown in the example below.
For example, in a system consisting of
two NDIR modules, two FID modules
and one CLD module, the tags could
be chosen from Table 2-1.
3. The user tag numbers should be
somewhat logical in their description
to avoid confusion. They should not
contain a period (.) so as to avoid
confusing PC software that attempts
to communicate with the NGA 2000
system.
NOTE
From the Listing of All Modules screen,
the Basic Controls of a selected module
can be selected. The I/O Module diagnos-
tics displays the I/O Module tag number
and allows it to be changed if necessary.
To change the Analyzer module tag
number, however, access Analyzer and
I/O, Expert Controls & Setup, Analyzer
module Setup, and then Analyzer Tag.
This is described in the corresponding
Analyzer manual. The initial Analyzer
module tag number is set during produc-
tion test and may be meaningless from
the user's standpoint. I/O Module tag
numbers initially will probably each read
"Analog I/O, Autocal I/O," etc.
4. Once all Analyzer modules and I/O
Modules have unique tag numbers,
binding can begin. Note that earlier
I/O Modules were not identified as to
which slot each one occupied in the
Platform (later units had this function
enabled). The slot number would al-
ways read "0." To remedy this condi-
tion, remove all but one I/O Module,
reinitialize the system and note which
I/O Module tag number remains on
the List of All Modules screen. Edit the
tag numbers in some unique fashion
to aid in subsequent recognition. Re-
insert each I/O Module one at a time
and reinitialize the system. Note or
edit the tag numbers that appear each
time.
5. If not identified, note the physical lo-
cation of each I/O Module for future
reference. A common problem in mul-
tiple Analyzer module systems is the
assumption that a module is not re-
sponding (no output response - volt-
age, current, alarms) when actually
the wrong I/O Module was being ac-
cessed.
6. From the Main Menu, make the fol-
lowing selections: System Configura-
tion and diagnostics, Network Module
Management, Bind Modules.
7. The screen shows one or more Ana-
lyzer modules. Select one, and press
the F2 (ADD!) softkey (or the right ar-
row). The screen will now list available
I/O modules.
8. Select one, and press Enter (↵). The
menu listing Analyzer modules will re-
appear, with the selected I/O module
indented under the Analyzer module.
9. Continue the process until all desired
I/O modules have been selected for all
Analyzers. Note that this screen
scrolls to show further Analyzer mod-
ules, simply press the down arrow key
to see more.
10. Press the F4 (BIND!) softkey. The
system will re-initialize itself, binding
all the modules as instructed.
11. To abort the process, or correct a
mistake, press the Left arrow (←)or
the F1 (Abort) softkey.
2-7 SAMPLE HANDLING
Rosemount Analytical offers many different
sample handling systems, either assembled or
as loose components. Sample handling is de-
pendent on the requirements of the particular
