Operating Instructions
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
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).
