I checked my NT nodes and the gateway number is also set to 1.

On the AW51, the AIS/FoxAPI gateway number is always 1.
Before AW51s, AIS ran on a VAX and spoke to as many as 16 (12? I can't
remember) gateways. These gateways were called INI-10s (later the INI-15
same hardware more functional software).
When AIS was ported to the AW51, the gateway argument was retained for
backwards compatibility of the calls.
Hope this helps.

Subject: FoxAPi for PI (Process Information Real Time Data
Base)
Hi list,
We are in process to install a real time data base (PI) in our
refinery in
order to integrate all the information existing, for example Foxboro
I/A
DCS, Factory Link, Honeywell TPS, etc.
We need information about the parameter "Location1" on PI
configarion with
FoxAPI that describes:
This parameter is the result of calculating (n*100 + x ) where n is
the
computer number in the range 1 to 99 and x is the IA interface
number or
gateway number. The computer number associates PI tags with an
interface and
is an arbitrary parameter that is set in the interface script file
fxbais.sh. The gateway number ranges from 1 to m, the maximum number
of
gateways set by the Foxboro AIS. A gateway number associates PI tags
with a
DNBI or an INI and corresponds to a gateway number configured in
AIS. For
the interface the gateway numbers are configurable parameters in the
script
file fxbais.sh. The two values combine to give a range for Location1
of 101
to 9900+m. The interface does not use the AIS options of load
leveling and
automatic assignment of gateway numbers.
Some one knows what is the "gateway number" in a configuration for a
DCS I/A
Foxboro?
Thanks for your help.
Sincerely,
Eudilson Nunez
