Core function
- Third party system data gateway
Support Modbus TCP and DNP3 industrial Ethernet protocols, collect data from third-party devices such as PLC, online analyzer, unit vibration monitoring device, electrical comprehensive protection, and smoke monitoring equipment, upload it to DCS operation screen and historical database, and achieve centralized monitoring of data throughout the plant. - Security system external communication forwarding
In the ProSafe-RS safety control station, upload safety signals such as interlocking actions, equipment failures, alarm states, etc. to the SCADA and upper management platform of the entire plant. - On site diagnosis of communication status
The panel is equipped with RUN, ACT, and ERR three color indicator lights, which provide intuitive feedback on module operation, data transmission and reception, communication fault status, and quickly troubleshoot network disconnections, IP conflicts, protocol mismatches, and other issues.
