Mobile (PDA) Browsing
The Sicon-8 Web server can also serve up a simplified page designed to
display on many modern PDAs by loading the page pda.htm. The pda.htm
page uses simple javascript to display the Sicon-8 data. It must be manually
refreshed (Get Readings button) to update the readings and, in order to fit
better into the PDA’s browser, the channels are broken into groups of 8.
Depending on your access level, you can view readings, acknowledge
individual alarms and control relays. No setup is permitted via the PDA page.
Your mobile device must support javascript in order to display the data. If you
enter your access code incorrectly, you may need to close and restart your browser to clear the
cache and cookies or you may not be able to log in at the desired access level.
Handling Alarms
The Web server indicates when alarms are
active and also shows you when meters or
status indicators are operating in potential
alarm conditions, even when an alarm is not
active. When a potential alarm condition
exists, the display turns yellow or red
depending upon which type of alarm
condition has been met. There can be
many reasons why an input might not have
active alarms, even though it is within the
general alarm set range. For example, a
momentary disruption might drive a reading
into the alarm range, but if it self-corrects
before the Sicon-8’s “Alarm validation” timer
expires, the alarm will not occur and the
display will automatically revert back to
normal. Alarms that have already been
acknowledged cannot set new alarms unless they first come back into the good range and then return to out-of-tolerance
conditions. Operating a relay, such as might be used to turn off a transmitter, also causes the Sicon-8 to take a set of
reference readings and ignore any condition that would otherwise be considered an alarm. It is impossible to create an
active alarm by operating a relay, unless there is a delayed reaction that exceeds the “reference delay” timer.
When there are active alarms waiting to be acknowledged, the upper
left segment of the display is the “Alarm Manager”, as seen at the
left. The Web server’s alarm manager is a simplified version of the
one found in the Sicontroller software. The alarm manager can only
display the five most recent alarms, but it does show you the total
number of active alarms. You can choose to acknowledge all alarms
or to remove them individually. If you remove them individually, then
the next oldest alarm will assume the bottom slot until you have cleared the list. All alarms acknowledged via the Web
server are put on the saved stack and can be reviewed later via the Sicontroller software or via DTMF.
