WellLynx™
Overview
Remote data collection, report-by-exception alarming, and increasing I/O count just
became easier and more cost effective with the introduction of the WellLynx from
eLynx Technologies. The device is a marriage of wireless I/P technology and intelligent
I/O to form a product with a powerful array of features particularly suited to the
oil and gas industry. It is a robust and economical solution that was specifically
designed to provide a window into the remote well site.
WellLynx is a unique, remotely configurable, communications device. In addition
to providing a path to remote meters, PLC's, RTU's etc. for standard poll and response
operation, it increases the I/O capabilities of the terminal device. It is also
a true report-by-exception device with alarm capabilities on analog inputs as well
as discretes.
Modes of Operation
Pass Through Mode
In the normal pass through mode, native protocol from the polling host is mapped
to the unit's serial port to complete the connection to a remote terminal device.
In this mode, spot data updates are collected from the meter on a scheduled basis,
typically at one to two hour intervals. In the same manner, historical/archive data
is collected usually on a daily basis.
Additional I/O
Today's flow computers have little, and in many cases, no I/O. Some have expansion
capabilities, but the add-on options themselves are often less than adequate and
always costly. WellLynx solves this dilemma with its ample on-board I/O, comprised
of four analog inputs, four discrete inputs, and two configurable D/I's or D/O's.
The I/O capabilities of the device function independently of the pass through mode
and as such, can be used in conjunction with the pass through mode. Data values
and discrete levels associated with the external I/O are made available as register
values and collected using standard modbus RTU requests. Configuration of the A/I's
or D/I's as alarm points activates the instantaneous alarming features of the WellLynx
Report-by-Exception
WellLynx utilizes SMTP, (e-mail), to provide notification of alarm conditions. Discrete
input changes as well as alarm threshold limits are instantly forwarded to the eLynx
data center where the device ID and corresponding customer location is identified.
The customer configured alarm message is then forwarded to all recipients in the
notification list. At the same time, the web interface is updated to reflect the
data and/or discrete change. The entire process typically takes 1 – 2 minutes.
