The HWg-PWR is a smart Ethernet gateway for remote energy metering and consumption monitoring.

The HWg-PWR measures the consumption of water, electricity and other energies, external meters with the M-Bus interface are used. Up to 3 / 12 / 25 M-Bus meters can be connected to the HWg-PWR unit. Individual meters (electricity meter, water meter, gas meter, heat meter etc.) are produced by third parties and connected via their M-Bus interface. HWg-PWR is a smart gateway that monitors energy consumption and warns about abnormal values The unit provides a Web interface, charts, SNMP and Modbus/TCP output, data logging, e-mail and SMS alerts, and much more.

IP WatchDog HWg-WR02a: Ping restarter

IP WatchDog HWg-WR02aIP WatchDog HWg-WR02a monitors the functionality of a device over IP (PING/WEB) or serial line (RS-232), automatically restarts it upon failure. The device can monitor two devices (two independent channels, two 110/230VAC relays). Industrial applications benefit from DIN rail compatibility.

IP WatchDog WR02a (ping restarter) periodically monitors the functionality of a device by transmitting or receiving a specified “I'm alive and OK” signal over IP or RS-232. If the correct reply is not received in time, the device is restarted with a relay. Failures are detected with five distinct methods, separately for each channel (Ping Tx/Rx, Web page request/push, RS-232 data). Web WatchDog WR02a allows flexible configuration – method of functionality detection, switchoff time when restarting.


Applications:
  • Operation monitoring / IP restart: servers / routers; IP video cameras; WiFi links / access points; industrial systems
  • Connectivity monitoring: activation of a back-up link; detection of connectivity outage (relay >> horn); monitoring of ADSL and cable modems; security and access control systems
