2.9 Transmitted
signals via interfaces
2.9.1 Service
interface
The service interface is operated using SynView. The transmitted information is
therefore identical to the SynView functions. Essentially, these are:
Parameter settings (read and write)
Put device in READY mode, block device, cancel errors
Read out actual values
Read transient recorder data
Read events log and diagnostic data
2.9.2 Operating
interface
The operating interface is used to transmit the data which are relevant to normal
operation:
Writing to digital inputs (Start, Stop, Release DB, selection of parameter set and
paralleling point, Reset)
Reading the digital outputs (ERROR, READY, OPERATING, U+, U-, f+, f-, back-
indication of paralleling point selection, all configured output signals)
Reading the status displays (
U <
Umax, s < smax,
<
max, U1/U2=0,
COMMAND, CHK RELEASE, BLOCKED)
Reading the actual values (
U,
, s, U1, U2, f1, f2, ds/dt, selected parameter set,
software version, command counter)
Reading the last event
2.9.3
IEC 61850 - Interface
Parameter adjustment values (exception: test functions, INVERSE and
TAP CHANGER-functions, as well as t block)
Set device to READY, BLOCKED, reset error
Reading the actual values
Writing to digital inputs
Reading the digital outputs
Reading the status displays
Reading the actual values (exception: selected parameter set, software version and
command counter).
