Overvis OPCB Series Equipment

Overvis OPCB-221B is a communication controller device suitable for industrial applications.

Acquire here: https://www.overvis.com/

The main function of OPCB-221B controller is to connect MODBUS equipment with Overvis cloud monitoring system or other SCADA systems. OPCB-221B operates as a MODBUS RTU<>TCP converter.

OPCB-221B

OPCB-221B is used to connect:

  • Refrigeration controllers
  • HVAC systems controllers
  • Agricultural smart devices
  • Power network relays, meters, and other electrical equipment
  • Industrial IoT devices
  • Industrial sensors and meters
  • Any other MODBUS-compatible electronics

Operation diagram

In conjunction with Overvis cloud monitoring, OPCB-221B devices provide:

Data collection:

  • Gather operational data points (any numeric values) from your equipment.
  • Store history of operational data, and get insights and analytics.
  • Collected data is fully exportable (Excel, CSV).
  • Hazard Analysis Critical Control Point (HACCP) reporting.

SMS and email notifications:

  • Configure alarms for operational parameter thresholds or connection errors.
  • Set up a “chain of responsibility” requiring alarm confirmations from personnel and escalating them in the absence of response.
  • All alarm actions are logged and ready for review.

Real-time monitoring and control:

  • Create dashboards with real-time information received from the equipment.
  • Visualize the data using open SVG format.
  • Use Google Maps API to display objects’ locations.
  • Use JavaScript and Overvis API to set up quick action controls for operation personnel.

And more:

  • Use templates to quickly create devices and alarms.
  • Manage access levels for different accounts inside one organization.
  • Works with dynamic IPs and bypasses firewalls.
  • Optimized mobile access.
  • Industry-standard encryption.
  • Overvis API allows the automation of control and can be used to load data into other management systems.
