5. OPC UA Products and Case Studies

OPC UA is now used for secure and open production systems that multiple vendors can adopt. This article shows OPC UA products and case studies.

OPC UA server

PLC and controller

Omron and major PLC and controller manufacturers worldwide offer products with the OPC UA server interface.

Machine Automation Controller NX701-1□□□/NX102-□□□□/NJ501-1□00

This controller with OPC UA server functionality can access PLCopen information models. This allows the controller to be directly connected to the higher-level IT system (e.g., SCADA) just by selecting controller variables.

The NX102 Series comes equipped with database connection functionality as well as OPC UA server functionality.
One controller can be connected to both the higher-level system and database: MES or SCADA via OPC UA, and SQL Server or Oracle Database used for traceability via database connection.

PLC and controller

The NX102 Controller supports not only OPC UA and database connection but various networks including EtherNet/IP, EtherCAT, MODBUS/TCP, and SLMP. It also offers IO-Link connectivity that makes communication down to the sensor level visible. Combining versatile connectivity with OPC UA brings IT and IoT to manufacturing sites.


OPC UA client

This section shows some examples of software with an embedded OPC UA client that is used together with an OPC UA server such as PLC.

(Note: The software below could be connected in the interoperability workshops (IOP) held by the OPC Foundation, actual systems, or demonstration systems. However, this does not mean that Omron recommends these products or guarantee the connection.)

Case studies

Update supervisory control system from OPC DA to OPC UA

The first-generation OPC technology OPC DA has been used for supervisory control and operation monitoring systems for factories. OPC UA is increasingly adopted for updating the systems. Improved points are:

・ Direct connection with PLC or control devices as well as Windows PC makes the system configuration simple.
・ In addition to simple numerical and memory data, structured data and semantic information can be exchanged.
・ Security is enhanced.

A broad range of OPC UA-capable SCADA, PLC, and controllers boost the adoption of OPC UA.

Standardize IT foundations with OPC UA for smart factories around the world

Manufacturing sites around the world have their own IT systems. M&A is one of the reasons. In order to improve productivity by leveraging information across the company, KPI and systems need to be standardized. The adoption of OPC UA as a globally standard, future-proof foundation solves this challenge.

Monitor operation of metalworking lines

OPC UA is used to collect and visualize data, such as operation information of CNC machine tools on metal parts processing lines, information of devices controlled by the PLC, and environmental information like power and temperature. One system can collect and manage both CNC and PLC information.

Security measure

Secured OPC UA can be used for cyber security and protection against manipulation of production data to achieve safe and secure manufacturing.

・ Cyber security measure
Most of actual applications are not disclosed, but Nagoya Institute of Technology in Japan published the details and results of empirical research on cyber security using OPC UA.

・ Protection against manipulation of production data
There is an increasing need to ensure the data integrity (DI) of production data collected from production lines and machines in the pharmaceutical industry. Data integrity means assuring the completeness and consistency of data.
OPC UA with digital signatures is sometimes used as a way to facilitate ensuring the data integrity.
