OPC UA Integration: GATEWAYS, SERVICES, RESOURCES

OPC UA Integration Overview

OPC Unified Architecture (OPC UA) is the modern, secure standard for industrial data exchange. It models rich, typed data and exposes it over encrypted sessions so HMIs, historians, MES/SCADA, BMS, and cloud systems can read, write, and subscribe to plant information reliably.

Chipkin makes OPC UA data easy to use across building and industrial networks. Our gateways connect to an OPC UA server, browse its address space, and map tags into open protocols such as BACnet/IP, BACnet MS/TP, Modbus TCP/RTU, and LonWorks—so your downstream systems see clean objects/registers with consistent names and units.

Use Cases and Industries

Expose PLC/SCADA OPC UA tags to BACnet/IP for building automation dashboards and alarms.
Bridge OPC UA process values to Modbus TCP/RTU for legacy drives, meters, and controllers.
Aggregate many vendor OPC UA servers into one normalized interface for BMS/EMS/Historian.
Segment networks (IT/OT) with protocol conversion at the boundary for security and uptime.

How Integration Works

Our gateway acts as an OPC UA client. It connects to your OPC UA server over opc.tcp or HTTPS, authenticates with certificates or credentials, then browses the address space to discover nodes. Selected nodes are mapped to BACnet objects, Modbus registers/coils, or LonWorks network variables with clear naming and engineering units. Subscriptions keep downstream points updated with minimal latency.

For deployments that need a physical appliance, we use the proven FieldServer QuickServer® hardware. This keeps the hardware discussion in one place while your protocol page stays focused on OPC UA specifics.

Security and Performance

Secure endpoints with certificate trust lists and encrypted sessions.
Role-based access to limit nodes and write access as required.
Efficient tag subscriptions and block reads to reduce server load.
Point counts sized per project; typical bundles start at 500 points and scale up.

Frequently Asked Questions

What is OPC UA?
OPC UA is a secure, platform-independent protocol that models and exchanges structured industrial data between devices and software systems.

How does the gateway connect to OPC UA?
It connects as an OPC UA client over opc.tcp or HTTPS, using certificates or credentials. We browse the address space and subscribe to selected tags.

Which networks can OPC UA be bridged to?

Common mappings include BACnet/IP, BACnet MS/TP, Modbus TCP/RTU, and LonWorks. Others are available on request.

Do you support write commands?
Yes. Where permitted, writes can be passed through to OPC UA nodes with role-based access and auditing.

How many points can I integrate?
Projects typically start around 250 points and can scale higher. We’ll size the solution to your tag count and update rates.
