Another situation which you might encounter is adding a SAT II
controller to an existing system and accidentally giving it the same
number as a SAT II presently “on-line.” Again, when you begin
to program the new SAT II controller, everything will appear fi ne
until you leave a screen or if you go to a summary screen. Only
now, all of the data is usually not missing. Generally, you get parts
of your data back and parts will be missing.
If you suspect you might have two SAT II controllers with the
same address, number 3 for example, the best thing to do is go to
the SAT II controller that you know is number 3, and remove the
2-wire communication loop from it. Then go back to the computer
and call up satellite controller #3. If the computer can still “talk”
to satellite controller #3, then there is another satellite controller
named #3 somewhere on the loop.
If a satellite controller was accidentally addressed #3, there will
be a satellite number missing. For example, if satellite controller
#7 was accidentally named #3, satellite controller #7 will not be
present. One way of telling which satellite controllers are “on-line”
is to go to the Satellite Summary Screen (page 3-38) and see which
satellite controllers the computer recognizes as being “on-line.”
Note: When a new satellite controller is connected to an
existing ECC/WCC II system, the data tables must be rebuilt
before the computer will “see” the new satellite controller on
the loop. Refer to the ECC/WCC II Operator’s Manual for
more details on performing the “Control-T” function to rebuild
data tables.
If satellite controller #7 was accidentally named #3, there would
not be a satellite controller named #7, and the computer will give a
“Non-Existing” message for satellite controller # 7.
