Depending on the version ordered, further interfaces are on the rear side of the device.
Thus a comprehensive communication can be built up with other digital operating
control and storage systems:
The service interface
can be operated via data or fibre optic cables. Communication
via modems is also possible. This enables remote operation from a PC using the
DIGSI
®
4 operating software, e.g. if several devices are to be operated from a central
PC.
The system interface
is used for central communication between the device and the
control centre. It can also be operated via data and fibre optic cables. Standardized
protocols for data transfer in accordance with IEC 60870-5-103 are available. This
profile also enables the integration of devices into the SINAUT
®
LSA and SICAM
®
automation systems.

FMS. The PROFIBUS FMS according to DIN 19245 with a very high capacity is a
widespread communication standard in the control and automation technology. The
profile of the PROFIBUS communication covers all types of information transmission
needed for substation control and protection systems. Via this profile the devices are
connected to the energy automation system SICAM
