Listing of All Modules.
The Listing of All Modules screen displays all
components recognized during initialization.
Any module connected (or disconnected) after
initialization will not be recognized until the
system is re-initialized. Verify that the net-
work recognizes all modules. If module(s) are
not recognized, the problem (e.g., cabling)
must be isolated and corrected before con-
tinuing.
Module Tag Names
Before binding, the user must rename (assign
a Module Tag) to all Analyzer and I/O Mod-
ules in the system, following a naming
scheme of the user's choice. (The initial
module tag names are set during factory test
and in all probability are meaningless to the
user.)
The only requirement for the naming scheme
is: Analyzer Module; the names logically dif-
ferentiate each Analyzer Module from the
other(s); I/O Modules; include information
relative to the Analyzer Module it will be
bound to.
For example, in a system consisting of two
NDIR Analyzer Modules, two FID Analyzer
Modules and one CLD Analyzer Module, the
Module Tag might be the following:
ANALYZER
MODULE TAG
I/O MODULE TAG
NDIR-CO2 ANALOG I/O IR1-CO2
NDIR-CO AUTOCAL I/O IR2-CO
FID-HIGH ANALOG I/O THC1-HIGH
FID-LOW ANALOG I/O THC2-LOW
CLD-NOX AUTOCAL I/O NOX
Assigning Module Tag to Analyzer Mod-
ules
1. Go to the Run Mode screen by pressing
the <HOME> and <DISPLAY> softkeys
Note which Analyzer Module measure-
ment is being displayed (e.g., ppm CO,
ppm NOx, or % O
2).
2. Go to the Analyzer Tag screen by se-
lecting <MENU> softkey, Expert Con-
trols and Setup menu, Analyzer
Module Setup menu and Analyzer
Tag. On the right side of the screen, the
default tag name will highlight (darken).
The tag name can now be edited.
3. Editing the Module Tag: The arrow keys
are used to scroll through a revolving
set of alpha (upper and lower case),
numeric (0 - 9), 82 special characters
and a space (the space appears follow-
ing the upper case "A"). The left and
right arrows change cursor position, the
up and down arrows scroll through the
character sets. Tag names can be as
long as 29 characters (including
spaces).
4. When ready to store the module tag,
press ENTER (tag stored in non-volatile
memory). Press the <HOME> and
<DISPLAY> softkeys to return to the
Run Mode screen.
To enter Module Tags for all other Analyzer
Modules, press <NEXT> softkey and repeat
steps 1, 2, and 3 above.
Assigning Module Tag to I/O Modules
1. Remove all but one I/O Module from the
Platform.
2. Go to the I/O Module ID screen by se-
lecting Main Menu, Technical Level
Configuration, Listing of All Modules
(select I/O Module from list), and I/O
Module ID. On the right side of the
screen, the default tag name will highlight
(darken). The tag name can now be ed-
ited.
