Product Overview

BASview3 is a stand-alone, embedded, web-based graphical interface for building automation and process automation systems. It can be accessed from any web browser – providing supervisory functionality to any BACnet/IP or Modbus TCP system. By using Contemporary Controls BASrouter or BASgateway products, additional protocols such as BACnet MS/TP and Modbus RTU are supported.

The BASview3 is simple to install and use. The BASview3 is housed in a DIN rail mounted metal enclosure and it is 24VAC/VDC powered for convenient installation. A 10/100 Mbps Ethernet connection is all that is needed for communication.

Supervisory features include animated graphic screens, scheduling, historical trending, runtime accumulation and email alarms. BASview3 will automatically toggle outputs and change setpoints on schedule, collect runtime and trend data, and monitor alarm conditions. As an embedded device, BASview3 uses Flash memory for internal storage to maintain its ruggedness. The BASview3 is totally self-contained, requiring no external application for its use. Multiple, simultaneous web browser users can access the device.

The BASview3 is ideal for small to medium buildings or processes that require a simple-to-use graphical interface with no licensing requirements. The BASview3 can handle up to 2000 nodes – a combination of devices, points, schedules, alarms, trends, etc.


  • Animated graphics
  • Internally maintained schedules with sunrise/sunset and stagger offsets with time retention on power loss
  • Trend collection, display and export
  • Runtime accumulation with email notification
  • Alarm condition monitoring with email notification
  • Calculated point values (average, min, max, etc)
  • Python programming language for controlling equipment
  • Database of up to 32 users and 32 user groups
  • Multiple simultaneous users with permission levels
  • Activity log for tracking important user actions
  • Template system for quickly cloning points, graphics, devices or entire networks
  • Calculations may be performed on data points
  • Support for up to 2,000 tree nodes which can be any combination of devices, points, graphics, trends, etc.
  • No software licensing requirements
  • No external tools or software required - completely self contained web browser interface

The BASview3 is housed in a compact metal enclosure that is DIN-rail mounted. It requires a 24VAC/VDC voltage source and could share power with other devices thanks to its half wave rectifier input power circuit. Powered by a 1.2GHz quad core ARM CPU, it has 1GB RAM and 8GB of Flash memory for data storage. The device has a capacitor-backed real-time clock. Installation is easy – simply connect the device to a BACnet/IP or Modbus TCP Ethernet network to access both BACnet and Modbus compliant equipment. For non-Ethernet based equipment, BACnet MS/TP to BACnet/IP routers or Modbus serial to Modbus TCP routers can be used. By using Modbus serial to BACnet/IP gateways, the complete system can be treated as a BACnet/IP system.
