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.
