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.
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
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.
