Petrol station operations incorporate multiple automated sensors and components to reduce the risk of harm to people and the environment. Many companies are turning to SCADA systems to oversee remote assets and improve management with intelligent computerised features.
A petrol station customer is using Advantech’s ADAM3600 modules to modernise data transmission and harden system security. Field sensors communicate via RS-232 and RS-485 using the Modbus RTU protocol, so the station needed a method to effectively aggregate data and send it to the SCADA system in an IoT-compliant and security-enhanced format.
A secure, cost-effective solution
In order to realise a cost-effective solution delivering unparalleled data security, the customer used Advantech ADAM data acquisition I/O modules and an all-in-one intelligent remote terminal unit (ADAM-3600) supporting OPC UA.
Installing an ADAM-3600 at each station allows it to act as an all-in-one RTU and I/O gateway, collecting Modbus I/O data and transmitting it to the central SCADA system via OPC UA. By consolidating field and enterprise communication securely in a single device, the customer minimised deployment costs with an investment in seamless data exchange for future upgrades and expansions.
After obtaining I/O data, the ADAM-3600 sends it to remote SCADA servers using encryption and sign-in certification—the innate security features provided by OPC UA.
The open platform architecture of OPC UA also provides access to an extensive number of cross-platform devices, empowering high scalability. Its timestamp feature provides the ability to mark sequences of data entries clearly and reliably, which is helpful for data analysis.
