OPC UA

OPC UA data collection with Proxus

Proxus connects to OPC UA servers from the gateway, with the security mode the server offers (No security, Sign or Sign & encrypt); server certificates are trusted in the hub’s Certificate Store. The wizard finds servers on the network; browse the address space folder by folder, pick the nodes, and the values arrive in your Unified Namespace.

Protocols and ports

Protocol: OPC UA

The port used when you leave Port empty, browsing the device, and finding servers on the network. The connection test works for every protocol.

  • OPC UA

    Discovery tries opc.tcp 4840 and 53530 and opc.https 53443. Server certificates are trusted in the hub.

    Port when empty: from the endpoint URL (opc.tcp://server:4840)

    Browse: Yes

    Discovery: Yes

Source: protocol reference

How it works

From the machine to your systems, in four steps.

  1. 01

    Add the device in the hub

    Choose OPC UA, enter its address and pick the gateway on the same network. Or let the wizard find servers on the network.

  2. 02

    Browse and pick the tags

    The gateway reads the address space, so you choose data points from a tree instead of typing addresses.

  3. 03

    Name it in the namespace

    Each value gets its place in the Unified Namespace (enterprise, site, area, line or cell, equipment), the same for every protocol.

  4. 04

    Deliver and act

    Send the values to databases, brokers, cloud and APIs, and run rules and anomaly detection at the edge.

Moving from Kepware

Running Kepware today?

Proxus imports channels, devices and tags from a running Kepware server. Siemens, Modbus Ethernet and OPC UA client channels are converted to the matching Proxus protocol; nothing changes on the Kepware side.

  • Runs at the edge

    The driver runs inside the gateway on the plant network. Data keeps being read when the link to the hub is down.

  • Buffered through outages

    Delivery to the hub and to every outbound target queues at the gateway (48 hours by default, up to 30 days) and is sent in order when the connection returns.

  • Nothing opens inbound

    The gateway connects out to the hub (port 7422, over TLS). Nothing on the plant network has to accept connections from the hub.

  • No per-tag pricing

    Tags, devices and users are not counted. You license gateways and data rate.
