OPC UA Distributed Ethernet IO Module BL205 to SCADA
Traditionally, most solutions utilize protocol gateways to convert remote I/O data to OPC UA, which requires additional configuration, and the software installed in the gateway's operating system increases the risk of the system being attacked by malware. To solve this problem, OPC UA IO BL205 communicates directly via SCADA and OPC UA cloud without additional gateway, saving additional cost and integration work.
