Softing is your OPC partner with over 20 years’ experience with OPC. Softing offers OPC and OPC UA solutions from chips, to embedded engineering toolkits, gateways, software middleware, and in-chassis modules for Rockwell Automation ControlLogix PLCs.

Softing builds ControlLogix in-chassis modules as an Encompass Partner with Rockwell Automation. The Softing OPC UA server module for ControlLogix:

Eliminates the PC, software, and OS in the middle and maintenance required in a PC connectivity solution by being an in-chassis OPC UA server module inside the ControlLogix rack
Allows you to browse the ControlLogix tag list for easy setup
Allows you to work with complex data in OPC UA rather than just data values in OPC Classic – this means that when a pump model is created, OPC UA carries the entire pump model, hierarchy, data types, and data values

FAQs for OPC UA

Q: What applications do we typically see for OPC UA?

A: Connect ControlLogix to SCADA, to DCS, to other PLCs, to SAP, to HMIs, field devices and sensors. One example is an airport using the OPC UA module in a ControlLogix PLC to exchange data with an HVAC systems from another vendor.

Q: What’s the benefit of putting the OPC UA server inside a ControlLogix PLC chassis?

A: With an in-chassis OPC UA server module, you can eliminate the server in the middle. When you get rid of the PC, you eliminate hassles with PC configuration, PC maintenance, PC software upgrades and backups, and you eliminate the challenge of just finding enough real-estate in the plant to place or mount the PC.

Q: What are some benefits of OPC UA versus the classic OPC protocol?

A: OPC UA benefits include:

Security – DCOM has been eliminated, and OPC UA includes encryption and authentication
Scalability – connectivity from sensors to the enterprise
Capability – OPC UA is more than just data values. OPC UA can include asset model properties and behaviors.
Platform independence – OPC UA is not limited to connectivity to Windows applications

Companion specs are being released for pre-configuring assets and behaviors, which were not possible for OPC Classic.

Q: How can I ensure compatibility with Industrie 4.0?

A: Any product being advertised as “Industrie 4.0 enabled” must be OPC UA capable. However, most plants have many devices and systems that are not OPC UA capable. Rather than replace these devices and systems, Softing offers protocol conversion solutions to help you build an OPC UA compatible infrastructure.

Note on OPC Foundation membership

OPC Foundation Corporate Membership is strongly advised for anyone serious about OPC UA client or server development.

There are multiple reasons for this:

OPC Foundation offers a non-production sample OPC UA code - free to members - which you will want access to even if you decide to purchase a commercial SDK or toolkit in addition
Compliance and marketing: OPC UA products will be far more saleable if they have been validated by OPC Foundation's compliance and certification process

So, while membership may have been considered optional for developers using earlier OPC specifications, if is strongly recommended for UA development.

Overview of Available SDKs and Toolkits

The following table gives an overview of OPC UA toolkit suppliers.

Toolkit Types		Platform / Language

*	* UA stack plus sample code only - not a full SDK. See note below.
Fully scalable, configurable, minimal RAM utilization, etc.

SDK and Toolkit Suppliers

OPC Foundation

Non-production OPC UA Example Code

The OPC Foundation non-production examples are collections of libraries and applications that illustrate the development of UA applications.

Note: OPC Foundation supplies a full UA examples for .NET core only. Support for C/C++ and Java is deprecated. While a stack and examples provides the basic communications infrastructure, a full SDK adds significant application layer libraries and classes to speed up application development. UA developers are recommended to look to one of the third-party vendors listed on this page.
