Perseus Energy 240

Perseus Energy 240 is the simplest and most affordable Perseus LAN monitoring device, designed to connect HW group's and third-party RS-485 Modbus/RTU sensors to the SensDesk Technology-based Portal. It can also be used as a Modbus/RTU to Modbus/TCP gateway.

Perseus Energy 240 supports up to 100 meters with 1000 variables, connected via RS-485 (Modbus/RTU).

It can read values from other network devices via generic SNMP, Modbus/TCP, MQTT and XML (for HWg devices).

It can analyze metered data from RTU / LAN devices with using local alarms, conditions and actions, and LUA scripts executed in the Perseus device.

Perseus Energy 240 is a gateway, it has only RS-485 interface, no RJ11 ports and no DI (Digital Inputs). 

Features: 
  • Ethernet: RJ45 (100BASE-T); WEB: Built-in web server
  • RS-485 (Modbus/RTU): 1x terminal block
  • Device Alerts: SNMP trap, email, (SMS / Calls with external SMS GW)
  • Portal Alerts: Email, SMS / Calls, Device Invalid Alert
  • Open API: SNMP, XML, Modbus/TCP, MQTT
  • Professional product: IPv6, SNMP Traps, SNMP v3
  • Security: Radius - IEEE 802.1X, Admin and user accounts, HTTPs (customer certificate)
  • Meters API (LAN): HWg devices XML, Modbus/TCP, SNMP, MQTT
  • Data processing: Condition & Actions, Virtual sensors, Scheduler
Applications and usage: 

Typical Applications:

  • Modbus GW (Modbus RTU to TCP)
  • Remote machine monitoring
  • Remote environmental monitoring of warehouse / storage spaces
  • Remote monitoring of technical room (sites)
  • Remote site data concentrator of all local sensors / meters
  • Remote environmental monitoring within the cabinet or telco site
  • Pharmaceutical / warehouse environment monitoring
  • Remote base transceiver station monitoring
  • Greenhouse monitoring

The Perseus Energy 240 LAN gateway is ideal for connecting third-party RS-485 (Modbus/RTU) sensors to an existing remote monitoring site. Perseus Energy 240 can analyze and send the data to any of the SensDesk Technology-based Portals. Third-party sensors can be connected via RS-485 (Modbus/RTU) or as LAN devices via the Meters API (SNMP, Modbus/TCP, MQTT).

Using the RS-485 (Modbus/RTU) as data input (Meters API) and Modbus/TCP as output (Open API), the Perseus Energy 240 can be used as a gateway from physical Modbus/RTU (RS-485) to Modbus/TCP (LAN). Measured data can be analyzed, connected to the Portal and used in any third party SCADA or SNMP based NMS system.
Perseus Energy 240 can be used as a Modbus RTU2TCP (RTU to TCP) gateway or as a Modbus/RTU to MQTT or SNMP converter.

Perseus Energy 240 combines data from external physical sensors / detectors connected via Modbus/RTU with data from other HWg devices connected via LAN. Local conditions, Lua scripting, calendar or periodic scheduler help to analyze the measured data.

The alert situation can be sent from the device as standalone alerts (Email) or analyzed & alerted from the Portal (SensDesk Technology) with Graphs, Virtual sensors, Device Invalid alerts, PDF reports or Portal account Open API (SNMP / XML). Perseus device can also individually share all measured values via the Open API (SNMP, MQTT, Modbus/TCP, XML, ...)

Standalone monitoring

  • Email alert can be sent from the device (requires SMTP server)   
  • Perseus Open API is available (SNMP, Modbus/TCP, MQTT, …)

Mobile App: HWg Monitor

  • Wall-mounted tablet showing all temperatures in the room / state of detectors
  • Data input: LAN devices / Portal user account
  • Android and iOS versions
  • All sensor values on one screen
  • Can be used as a sensor reading display in your pocket / on the wall

Using free of charge Portal service (HWg-cloud.com):

  • Perseus 240 can be easily connected via LAN
  • Email alert with high/low temperature can be sent from the Portal (long-term reliable)
  • Device Invalid (disconnected) email alert is available from the Portal
  • One value graph with short history is available
  • Alarm escalation is available (email only)
  • Remote relay output switching based on sensor 
  • Central alerts overview & management
  • Free of charge service from HW manufacturer

Using paid Portal service (Portal providers):

  • All features from HWg-cloud.com are available
  • Email, SMS, Voice call alerts (from the Portal)
  • Virtual sensors in the Portal (average over several sensor, …)
  • Multigraphs with several years of history
  • User account API: SNMP or XML
  • Reports (PDF)
  • Multi-user accounts
  • SensDesk.com (SaaS service) can be used (or any Portal Provider)
