SG-gateway with PROFINET
Bridging the gap between industrial and energy communication
The SG-gateway supports the communication protocols used in the energy sector, including IEC60870-5-104, DNP3 and IEC61850 and enables connectivity for energy devices to PROFINET-based automation systems. On top of that the simultaneously usable OPC-UA and MQTT functionality empower direct integration into the companies’ cloud-based applications.
The PROFINET interface for Siemens-PLCs implements an isochronous real-time PROFINET device interface with an integrated 2-port switch, allowing seamless network integration regardless of network topology.
In addition to PROFINET, IEC and DNP3 protocols, other electric equipment in the field can also be connected via Modbus-TCP and RTU. As an option, the SG-gateway can also include a 3G modem for remote connectivity.
