R = data to be read from the unit
W = data to be written to the unit
The data transfer codes L, B, C and T have been
reserved for the event data transfer between the
relay module and the substation level control
data communicator.
The event register can be read only once by the
L command. Should a fault occur, for instance,
in the data transfer, it is possible, by using the B
command, to re-read the contents of the event
register once read by means of the L command.
When required the B command can be re-
peated.
The set values S1...S5 are the alerted set values
currently used by the relay. These values can be
set either by means of the setting knobs and
selector switches or by remote control. The
values S11...S15 are set with the setting knobs
and the switches of the relay module. The values
S21...S25 are percentage factors to be multi-
plied by the set values given with the setting

V200 R, W 1...254
V205 R e.g. 052 B
F R SPCJ 3C3
L R Time, channel number and
event code
B R Time, channel number and
event code
C R 0 = normal state
1 = module been subject to
automatic reset
2 = overflow of event register
3 = events 1 and 2 together
C W 0 = resetting

knobs. The set values S21...S25 can be both
read and written. A condition for writing is that
the password, V160, for remote setting has been
opened and the potentiometer settings must be
valid, V150=0. The variables S31...S35 contain
the actual remotely set values.
The remote setting percentage of variables
S21...S24 can be given a percentage value within
the range 0...999. This means that set values
outside the limits of the specified setting range
can be given to a certain parameter. However,
the proper operation of the relay is guaranteed
only for set values within the setting range limits
specified in the technical data.
Activation of the self-supervision input (V165)
prevents the relay from operating as long as the
self-supervision input is active and the IRF
indicator is lit.
