...There are many types of "automation equipment", process controllers, environmental monitors, building controls -- and much more, that can be connected to AFN. These range from PC's to manufacturing process control systems, to alarm systems, etc., which routinely send information out through a standard RS-232 serial port, parallel printer port, etc. Simply connect AlphaSense for Networks (AFN) to the data port of the host equipment. Then, suppose the user sets AFN to trigger (using, for example, Rulsesets 1,2, and 3 out of 20-50) on these 3 seperate "matchstrings": Reject, err, and STAT. Then, assume that these are some of the data strings which might be output from the host at any time…
Message 1: Offshore platform drill 2B at high temperature.
Message 2: Stamping Machine 6 Reject Level Exceeded.
Message 3: Computer Room cooling failure - error Code 10.
Message 4: Chlorine tank 5 - OSHA environmental limits in range.
Message 5: Lockdown at guardstation for cellblock W7 confirmed.
Message 6: Lab test PH STATION report - Acid bath at low level condition.
Message 7: Unauthorized entry at door 12 - CardReader
ID invalid.
Each data message received from the host is scanned
to see if it contains any of the matchstrings. Messages 2,3,5,
and 6 each contain a matchstring, so immediately on their arrival,
AFN delivers an exact copy of those messages to the user-specified
"destination(s)" !! ...And different recipients can
be chosen for each matchstring action, so that the proper people
are alerted for each topic.
This example illustrates the AFN "data
forwarding" feature, where the actual data from the host
equipment was used as the message contents. Alternatively, the
user could specify a fixed content message which would always
be delivered each time the appropriate "matchstring"
was detected in the host's data stream.
In this example, the data port of the user's equipment
would probably have been connected to a printer to show the data
messages. Of course, people would have to be at the printer to
read the message. By adding AFN, all the host data is intelligently
scanned for content which the user(s) want to be informed of,
and important data is quickly delivered to the right people wherever
they may be!
AFN supports the powerful Regular Expression (Regex) syntax, which provides very comprehensive parsing and rule-based evaluation of the incoming data. Regex expressions can be very complex, or simple. For example, a simple "match on abc" rule is entered simply as "abc" (without quotes). The AFN Regex processing logic makes available to you a powerful and customizable processing engine. If you don't want to "do it yourself", Compuquest, Inc. can provide Regex expression creation for your specific needs - just contact us.
