ADVER TISEMENT Communications Gateway Provides Access To Transfer Switch Information From Web-Enabled Devices The Russelectric DTWG Web Server Communications Gateway accessory to the company’s RPTCS Automatic Transfer Switch Control provides access to automatic transfer switch (ATS) data from any personal computer, smartphone, tablet, or other web-enabled device running Java. It also serves as a pass-through gateway, allowing access to the ATS through SCADA or building automation systems. Receive E-Mail Alerts, Review Event Logs, Diagnose Power Problems The DTWG can provide e-mail alerts to facilitate power management. By remotely reviewing events that took place prior to a problem, personnel can identify the nature and cause of problems and act to prevent future occurrences. Through the DTWG gateway, users can also remotely schedule and initiate equipment exercises. Check the Status of Any Russelectric ATS Remotely Download up to 30 Days of Data for Analysis With the Russelectric DTWG, users can view stored information from anywhere inside or outside a facility, at any time of the day or night. Displayed on a user-friendly dashboard, this information includes real-time and historical ATS/engine/ exerciser status and performance data for normal and emergency sources; switch configuration; trends; event logs; metered voltage (phase-to-phase); frequency; percent of unbalanced current; percent of unbalanced voltage; accumulated energy (KWH, KVAH, and KVARH); and per-phase and 3-phase totals for real power (KW), apparent power (KVA), reactive power (KVAR), and power factor. The DTWG stores 30 days of historical data, which can be easily downloaded for analysis of power usage, power quality, and reliability for the monitored facility’s load. This data can be used to identify historical and real-time trends in energy usage as well as opportunities for energy-cost savings. Often, data will be detailed enough to allow analysis by work shift, enabling both macro and micro power-usage recommendations. Supports All Major Fieldbus Networks The standard Russelectric DTWG supports Modbus-RTU through its serial ports and can serve as a Modbus master or slave. With optional, field-installable modules, the gateway can be configured for the following networks: Profibus, CANopen, EtherNet/IP, Profinet-IO, ControlNet, DeviceNet, EtherCat, Modbus-TCP and Modbus-RTU.
