the “BIND” softkey is pressed, the
system will reinitialize automatically.
9. To achieve binding between other
Analyzer modules and I/O Modules,
return to the top level display screen,
select the next Analyzer module and
repeat steps 5 through 7. As I/O
Modules are bound, they disappear
from the Select I/O Module screen be-
cause they are no longer available for
binding. In a system with only one
Analyzer module, no I/O Module
would appear in the Select Module
screen since they are automatically
bound upon initialization of the sys-
tem.
NOTE
Do not press the “UNBIND” softkey, do-
ing so would unbind all modules, re-
quiring the user to repeat the complete
binding procedure. However, if a bind-
ing mistake is made, the only way to cor-
rect the mistake is to press “UNBIND”
and repeat the binding procedure. Also,
do not press the “RE-INIT” softkey dur-
ing any of the automatic re-initializations
in the binding process. If the “RE-INIT”
softkey is pressed, this will abort the
binding process and all prior binds will
be removed.
10. Verify all bindings by selecting View
Bindings in the Module Binding
screen. A “miss-bound” module can
lead to confusion and mis-diagnosis of
system problems. Use the NEXT
softkey to move from one Analyzer
module to another in this screen.
e. Binding Procedure - Software v2.3 and
higher
In an NGA 2000 System that contains only
one Analyzer module, binding between that
Analyzer module and any I/O Module(s) will
occur automatically upon startup.
If the system contains multiple Analyzer
modules it will be necessary to bind each
Analyzer module to the associated I/O
Module(s). To bind a newly installed I/O
Module to an Analyzer module perform the
following steps:
1. From the Main Menu, make the fol-
lowing selections: Technical Level
Configurations, Listing of All Modules.
The Listing of All Modules screen
shows all NGA 2000 components
(Analyzer modules, I/O Modules and
Platform [Control Module]) recognized
during the initialization of the network.
Any module connected (or discon-
nected) after initialization will not be
recognized until the system is reini-
tialized. Ensure that the system rec-
ognizes all modules on the network. If
it does not, the problem must be iso-
lated and corrected before continuing
further.
2. On the Listing of All Modules screen,
ensure that each module has a unique
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 num-
ber can be set as shown in the exam-
ple 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
1-1.
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 diagnostics of a selected module can
be selected. The I/O Module diagnostics
displays the I/O Module tag number and
allows it to be changed if necessary. To
change the Analyzer module tag number,
however, access the Analyzer Manufac-
turing Data screen by making the fol-
