Softing Opc Ua Client
Sponsored by: Softing
The central.NET client and the OPC Unified Architecture (UA) information model of the SmartFactory KL demonstration factory have been developed using the OPC UA.NET Client Development Toolkit from Softing Industrial Automation. In addition to providing the toolkit, Softing also supported the development with OPC UA training. Toolkit for OPC UA development in embedded systems Posted on by Ramin Esmaili Softing’s OPC UA embedded toolkit is based on the ANSI C standard and features a low memory footprint as well as minimal requirements for computing power. DataFEED OPC UA.NET SDK enables the fast integration of OPC UA into.NET applications for Windows. A comprehensive collection of libraries with a comfortable, clearly documented programming interface and associated sample applications are included and enable a fast time-to-market for the implementation of OPC. How-To connect uaGate SI with an OPC UA ClientMore Information: Softing OPC. For this an OPC UA Server is used, e.g. The KEPServerEX, to get the data as a client from the OPC Classic Server and to make this data available via OPC UA firewall friendly. OPC UA over TSN The TSN stands for Time Sensitive Network and describes the requirements of machine networks with deterministic response times.
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?
Softing Opc Ua Client Portal
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.
