locking conditions for switching (e.g. switching error protection) can be established
with the aid of integrated, user-configurable logic functions.
A series of operating messages provide information about conditions in the power sys-
tem and the 7SJ62. Measurement quantities and values that are calculated can be
displayed locally and communicated via the serial interfaces.
Messages of the 7SJ62 can be indicated by a number of programmable LEDs on the
front panel, externally processed through programmable output contacts, and commu-
nicated via the serial interfaces (see Communication below).
Important events and changes in conditions are saved under Annunciation in the
Event Log or the Trip Log, the latter being used for faults. Waveform capture is avail-
able, as an option.
Serial interfaces are available for communications with PC's, RTU's, and SCADA sys-
tems.
A 9-pin D-subminiature female connector on the front panel is used for local commu-
nications with a personal computer. DIGSI
this port. Using the DIGSI
relay, Realtime operating quantities can be viewed, Waveform capture and Event Log
records can be displayed, and controls can be issued.

A DIGSI 4 service interface port, a system (SCADA) port and a time-sync port (IRIG-
B or DCF77) are optionally available on the rear of the device.
A rear service interface can be supplied as RS-232, RS-485, or multimode fiber optics

type ST. DIGSI 4 software is required to communicate via this port.
A rear system interface can be supplied as RS-232, RS-485, or multimode fiber optics
type ST for communications between the 7SJ62 and a PC's, RTU's, or SCADA sys-
tems Standard Protocols, IEC 60870–5–103 are available via the system port. Inte-
gration of the devices into the automation systems SINAUT
take place with this profile.
Alternatively, a field bus coupling with PROFIBUS FMS is available for the 7SJ62. The
PROFIBUS FMS is performed in accordance with IEC 61850, is an open communica-
tions standard that particularly has wide acceptance in process control and automation
engineering, with especially high performance. A profile has been defined for the
PROFIBUS communication that covers all of the information types required for protec-
tive and process control engineering. The integration of the devices into the energy
