I've got TAC on this case, but they might not be the best place to go for
this, so I thought I'd throw it on the list server to see if any of you
Foxboro wizards can help me out:
We have AIM*Historian, and it does not provide any tools to extract alarm
messages into a text format. Unlike the legacy historian, AIM*Historian
doesn't generate a flat circular file like "almhist", it actually stores its
data in tables that are located in files that you can store for years. I
know what tables they are stored in, and I even know the syntax of the C
call to access the tables. Unfortunately, I cannot figure out all the
little important things you need to do to write a C application for this
purpose, such as what header files to include, how to declare the variables,
what kind of output the C call actually generates, and how to compile and
link the finished source code.
The AIM*API documentation provides the syntax for the C call, which is
called fh_FdbMsgQuery, but it doesn't have a sample program using this call,
which is really what I need. Someone at Foxboro developed a C program
called fh_sacego that queries the same tables and extracts System Monitor
messages and Operator Action Journal messages, presumably using the same
calls. If someone at Foxboro could send me the source code for this
application, or a stripped down version that at least illustrates what is
required to properly declare the variables, handle the output, and compile
and link the C code, it would be much appreciated. Anybody up to the task?
Has anybody else written any code with AIM*API?
Thanks,
Tim
