With its comprehensive OPC UA solution, Bachmann electronic is consistently focusing on open standards to enable seamless and secure networking in automation technology. The pure software solution, which runs directly on the control CPUs without additional hardware, offers a manufacturer-independent interface for visualizations, production data acquisition, or edge/cloud solutions. Communication can be encrypted according to current security standards, ensuring protected data transfer.
The OPC UA server provides complete and transparent access to the shared process data of the controller, with values, time stamps, and quality information being updated automatically. A flexible alarm system monitors variable values and displays faults with selectable acknowledgment models. OPC UA File Transfer allows access to the control system’s file system, while the integrated security concept manages user-specific access rights to variables and files and logs all write accesses. Configuration is carried out centrally in the SolutionCenter, supplemented by an API for controlling the alarm system from within the application.
At the same time, the OPC UA client of the control software enables data access to external servers via read, write, subscribe, and method call. Subscribe and write operations can be configured so that the values are automatically available in the process image. The supplied client library, according to PLCopen and C/C++ interfaces, offer maximum flexibility for application development. In conjunction with freely programmable methods in atvise® scada, individual private cloud solutions can be implemented.
Two additional options are available for classic Windows-based environments in existing systems (brown field environment): The OPC Enterprise Server is designed for large-scale systems. The OPC Standard Server is designed for smaller installations.
