OPC UA is a platform, vendor, and language independent technology that can be used at all levels of an organization. It helps to set up secure, standardized, and high-performance communication channels across the enterprise. The open architecture design supports a wide range of hardware and software applications from different vendors, thus ensuring enterprise wide interoperability. OPC UA enables implementation of IIoT and AI-based solutions to bring your organization into the industrial 4.0 fold.

Utthunga offers comprehensive and standardized OPC UA application development services for process/factory/power/building domains, machine builders, and industrial software companies. Our OPC UA Stack is specifically platform independent, minimizes development cost, time to market and bill of materials cost for OEMs and end users who want to add OPC UA Server functionality to their products.

Why OPC UA application development is essential for industries?

Industries, irrespective of their domain, are aggressively adopting OPC UA Stack applications for industrial interoperability. Some of the ways in which industries benefit from using OPC UA based solutions are:

  • The standardized interface enables easy OPC UA integration and enterprise-wide data visibility and access
  • Secured and direct communication across all automation levels
  • When used with industry communication protocols like HART, Modbus, Ethernet/IP, PROFIBUS, PROFINET, etc, OPC UA integration enables easy integration of legacy systems into mainstream
  • Allows for contextual interpretation of data at each layer from shop floor to enterprise level

FAQs

The standards suggest you to use FIPS 140-2 based compliant algorithms so and so, but the standard will not suggest how to implement it. Also, there is a document released by foundation “Practical Security Recommendations for building OPC UA Applications” you can referee that to get some idea.

There is a limitation and dependencies in OPC classic. Especially, concerned with DCOM and COM configurations. OPC UA is built and being improved keeping security in mind, but it is not the case with classic

If the client is OPC Classic, then it can only connect to OPC Classic DA Server. However, if you have OPC UA server, then you can use it to convert to OPC DA data and then be able to connect using OPC Client.

The certificates are created by both server and client. It follows the x509certificate format.

There are no separate tools available in the market to manage the security certificates. It’s up to OPC Pub/Sub development vendor to provide the tool required to generate the certificate keys. The user shall be able to select the tool that works best for them if it is compliant with the OPC specifications.

“Thank you for your interest in approaching Utthunga for implementing an OPC UA solution for your Windows application. The simplest approach is to have a COTS solution that allows you to customize your OPC UA application based on your business requirements and needs. In case, you need assistance in the stack selection and implementation of different OPC UA applications, we can help you as our Industrial Connectivity solutions leverages the domain and technical expertise of our competent team of developers. We’ll also help you determine the scan times and tag limitations based on the target machine’s hardware and software configurations. We are a vendor neutral supplier of certified OPC UA and OPC based data interoperability products for control automation, to ensure secure, authenticated, and encrypted communications across various network topologies. “

Yes, Device Security and OPC UA security (or any protocol/application level security) are two totally different features.

Device security includes communication security along with data security, identifying vulnerabilities to setup protection mechanisms, monitoring, notification and configurability. The scope of OPC UA security covers only communication security.

For OPC UA security, usually the OPC UA stacks depend on other security stacks like OpenSSL, mbedTLS etc.

Due to the inherent features of the device security, it can’t be provided with a stack. However, it will be provided as a service. This is because the security aspects of every device vary from device to device based on hardware, form factor, firmware design, how the device is going to be used by the end customer, etc.,

To answer your question of whether to purchase a separate stack or opt for a service, we can collaborate for a suitable engagement model that involves a security consultant, developer and tester along with your product development team throughout the product development lifecycle including maintenance (as new types of security threats being discovered, to keep the product up to date from security aspects).

Thank you for reaching out for our help with your OPC related issue. To enable you to collect all the OPC data in one server in a central location, please follow the below steps.

  • Install Server side component in the 7 independent DCS network which shall all expose data over OPC UA
  • In Firewall settings, enable the port which is used by OPC UA Server in the Server side component
  • In Central location, install Client side component and configure such that it shall connect all OPC UA Server (Server side component(s)) running in 7 independent DCS network
  • Now, the Client side component will act as a central server, which shall collect all the OPC data from different locations in a secure manner

You can directly reach out to our OPC experts for a more detailed understanding of our OPC capabilities and services that meets your specific requirements.

Usually the certificates are generated in their trusted path. But, whenever the application tries to connect, the certificates are moved to rejected folder path and the end-user need to manually copy that certificate to the trusted location. This procedure is applied for both Client end and the server end.

To answer your question

  • On server side, it shall be using port 636.
  • On client side, it depends on OPC UA Server port configuration However, for machine discovery it uses port 4840.
