Depending on the individual ordering variant, additional interfaces are located on the
rear side of the device. They serve to establish an extensive communication with other
digital operating, control and memory components:
The service interface can be operated via electrical data lines or fibre optics and also
allows communication via modem. For this reason, remote operation is possible via
personal computer and the DIGSI
®
operating software, e.g. to operate several devices
via a central PC.
The system interface ensures the central communication between the device and the
substation controller. The service interface can be operated through data cables or
fibre optic cables.
The device has a field bus coupling with PROFIBUS FMS. The PROFIBUS FMS
according to DIN 19 245 is an open communication standard with particularly wide
acceptance in process control and automation engineering, with especially high per-
formance. A profile has been defined for the PROFIBUS communication that covers
all of the information types required for process control engineering. The integration of
the devices into the power automation system SICAM
®
can also take place with this
profile.
In addition, standardised protocols in accordance with IEC 60 870-5-103 are available
for data transmission. The integration of the devices into automation systems from
other manufacturers can also take place with this profile.
Optionally, you can use an additional serial interface for Inter relay communication. It
takes over communication with other SIPROTEC
®
4 devices, regardless if the device
is connected to the control center.
The process bus interface allows a direct communication with SICAM HV modules.
They communicate process data between the Bay Processing Unit and the device
control (of circuit breakers, disconnectors and ground switches). Here, a PCU (Pro-
cess Communication Unit) serves as a communication link between controller and
process bus.
