Calem Integration 8: Device Integration via OPC/UA

Calem provides a connector to integrate with OPC/UA for sensors in the coming release of Calem R2025h (December 2025). 

  • OPC/UA (Open Platform Communications – Unified Architecture) is a standardized way for industrial devices to publish data for other systems to use.
  • Calem OPC/UA connector allows Calem to get sensor readings from equipment and devices for asset health monitoring.

Calem OPC/UA connector works with VPN and OPC/UA servers to get sensor readings.

  • Calem OPC/UA connector is a Calem instance.
  • It is configured in Calem Cloud for Calem Cloud customers, or installed in customer network environments for on-premise deployment.
  • VPN setup may be necessary at the connector for accessing OPC/UA servers.
  • The connector communicates with Calem via Calem API.
  • See Calem Admin Guide for more info.
  • Clients may contact Calem Team for help in setting up the connector.
