ICP Australia is proud to introduce ICP DAS’s IEC850-211-S, which is a Modbus TCP to IEC-61850 Gateway. IEC 61850 is an international standard defining communication protocols for intelligent electronic devices at electrical substations. It is developed by the International Electrotechnical Commission’s (IEC) Technical Committee 57 reference architecture for electric power systems.

The objective of the standard is to specify requirements and to provide a framework to achieve interoperability between the IEDs supplied from different suppliers. This protocol can run over TCP/IP networks or substation LANs using high speed switched Ethernet to obtain the necessary response times below four milliseconds for protective relaying.

IEC850-211-S is a network gateway allowing IEC-61850 MMS client to access Modbus TCP network as a Modbus TCP client. IEC-61850 protocol is used in substation automation. The IEDs exchange information with other IEDs or SCADA via IEC-61850 protocol for protection and control devices. IEC850-211-S support Logical Node GGIO and Data Object Ind, IntIn, SPCSO, ISCSO. It also supports data set and unbuffered report function to exchange data with a client.
