Made possible by: Field-level communication with OPC UA over TSN, OPC UA security
Starting position
A machine builder is developing a charging station for electric cars. To do this, they need a future-proof, vendor-independent communication solution.
Problem
- Power fluctuations: The e-charging station is subject to power fluctuations, which must be compensated for in a time-critical manner.
- Remote connection: The charging station must permit remote access for maintenance, monitoring and cost accounting purposes.
- Network communication: Communication within the e-charging station must be vendor-independent and secure.
Solution
Switch to an OPC UA over TSN network. The OPC UA publish/subscribe mechanism enables the power fluctuations to be compensated for promptly. OPC UA security mechanisms enable secure IT communication and data retrieval from the cloud.
Advantages
- Interface defined only once
- Easy user management: Clear display of access authorizations through OPC UA role and rights management
- Vendor-independent communication
