Table 2-1. User Tag Numbers
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-
lowing selections: Technical Level
Configuration, Service Menus, Manufac-
turing Data, or Expert Menu, Analyzer
module Setup, Analyzer module Tag. The
initial Analyzer module tag number is set
during production 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, SCAL,", 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. Note the physical location of each I/O
Module for future reference. A com-
mon problem in multiple Analyzer
module systems is the assumption
that a module is not responding (no
output response - voltage, current,
alarms) when actually the wrong I/O
Module was being accessed.
6. Select the top level display that shows
multiple module output. Select the
Analyzer module to be bound to an
I/O Module, ensuring that it is identi-
fied with the correct tag number.
7. From the Main Menu, make the fol-
lowing selections: Technical Level
Configuration, System Setup, Module
Binding, Select Modules.
8. Ensure that the Analyzer module se-
lected is, in fact, the one to which an
I/O Module is to be bound. Select the
I/O Module to be bound. The screen
will appear as “Proposed New Bind”.
If the proposal is correct, press the
“BIND” softkey. If incorrect, return to
the Module Binding screen and re-
select the correct I/O Module. When
