Product Guide
The advantage of using data mirroring instead of standard communication, such as IEC
60870-5-104, is that the data mirroring communication is much more efficient and the
required engineering work to build up the system is minimal. Several special functions,
such as event buffering during communication breaks and handling of hot stand-by
configurations, are automatically taken care of.
The data mirroring takes place between a host and an image. The host is the source for
the process data and the image is a copy of the process data. The SYS 600C node that
receives the process data, for example, through IEC 61850 or LON, is the host. This
process data can be mirrored to another SYS 600C node, which acts as an image.
OPC connectivity
OPC is a de-facto interface standard connecting various devices and systems within the
process automation industry. OPC is becoming more and more used and accepted also
in other application areas and within the power industry. It defines exchange of data
between a server and a client. The server provides data and the client uses the data. The
client can also write data (commands, parameters, and so on) to the server.
SYS 600C provides OPC connectivity both in forms of clients and servers, that is, SYS
600C can receive data from a device or system that provides its data through an OPC
server. SYS 600C can also provide its data to another system that acts as a client.
