GRBTU (model 3BSE013175R1) is a special communication gateway module for ABB Industrial800xa or Symphony Plus system, which is used to realize protocol conversion and data integration between industrial equipment and control system. Mainly used in power automation, process industry and infrastructure fields.

2. Core functions and features
   Protocol support:
   Support IEC 60870-5-104, DNP3, Modbus TCP/RTU and other standard industrial protocols, and be compatible with third-party equipment (such as protective relays and intelligent instruments).
   Optional configuration supports OPC UA or PROFIBUS DP (firmware version needs to be verified).
   Hardware design:
   Modular structure, pluggable terminal design, convenient for on-site maintenance;
   Dual Ethernet ports (10/100 Mbps), supporting redundant communication;
   Working temperature:-20 C to+60 C, in line with the industrial EMC standard (IEC 61000-6-2).
   Data processing:
   Provide data caching and timestamp functions to ensure data integrity when communication is interrupted;
   Support bidirectional data mapping between SCADA system and field equipment.
3. Typical application scenarios
   Power system: substation automation (communication with ABB REL670 protection device);
   Water treatment plant: pump station monitoring and PLC data acquisition;
   Oil and gas: protocol conversion between remote RTU and central control system.
