DATA ACQUISITION


Data floods in with multi-asset DAQ


Data collection from network router helps water company manage multiple widely spread assets N


ordikeau, a water and wastewater treatment company in Quebec province, Canada, is using the Fetch Data Collector software from MAC Solutions to log data from critical assets and equipment in real


time and provide data for alarms and early notifications of any equipment or process issues. Fetch Data Collector software is designed


specifically for Ewon remote access VPN routers that makes data collection easier, faster and more secure. It collects historical information from the data storage memory within the Ewon Flexy remote access VPN router and can be configured in an easy three- step process with minimum technical knowledge and minimal configuration within each Ewon device. According to Martin Fafard of Nordikeau, using


the software with a router provides staff and clients with live data and dashboards via smartphones and laptops using alarms and notifications.


REMOTE CONNECTION The collector can connect to any number of remote machines via the Ewon device and Talk2M Remote- Connectivity Cloud. It can also be configured to work locally, for end-users who wish to store production data in local machines and then archive it into a central storage system, for example. Data collected can be stored to either ODBC-compliant databases or a series of CSV files, with fully customisable file formats and naming conventions. Nordikeau has configured the router to collect


data from more than 50 sensors connected to critical processes and equipment at one plant. Such data includes water levels in tanks and reservoirs, pump speeds, turbidity, network pressures and flow rates. These are critical parameters where the data needs to be collected or refreshed regularly. The Fetch Data Collector stores the data in a SQL


Server database at Nordikeau and shares it with the company’s Nordicité software, with which staff and clients can visualise the information in customised dashboards. Alarms and notifications can be sent via SMS text messages to engineers or clients on remote devices, such as mobile phones or laptops. Fafard recalls an incident where Fetch Data


Collector came to the rescue: “One of the reserve water levels in the plant reached a critical level and so an alarm notification was triggered. We were able to react quickly and find the source of the problem,


❱❱ Nordikeau is using Fetch Data Collector to view real-time data from critical assets at a water treatment plant in Canada


which turned out to be a breach in a water pipe that was losing water quickly.” Nordikeau is using Fetch Data Collector on one treatment plant, but plans to roll out the software to other sites in Canada.


ROUTER BASED DAQ Data acquisition takes on a new dimension when channelled through network routers and web services, allowing the data to be more accessible in its raw form or as analysed, actionable information in the form of complete reports or triggered alarms. In this case, Nordikeau is using Ewon + Talk2M


as a remote access system, which provides a secure, reliable method to connect with machine control devices (PLCs, HMIs etc), anywhere in the world, using the Internet. It consists of two elements: Ewon remote-access VPN Routers and the Talk2M cloud- based connectivity service. This combination provides the ability to take


advantage of real-time PLC monitoring capabilities as well as customisable emails, and web server pages, as well as data and event logging. T&TH
