Remote transfer data

In addition to the event data all input data (I
data), setting values (S values), recorded infor-
mation (V data) and certain other data of the
overcurrent module can be read via the SPA bus.
Parameters marked with a W letter can be
altered via the SPA bus.

When setting values are altered via the MMI on
the front panel or via the serial bus, the module
checks that the entered parameter values are
within the permitted setting range. The relay
module refuses to accept a too high or a too low
setting value, but keeps the old setting value
unchanged.

Altering parameter values via the serial bus
usually requires the use of a password. The
password is a number within the range 1…999.
The default password is 1.

The password is opened by writing the password
number to parameter V160 and closed by writ-
ing the password number to parameter V161.

The password is also closed on loss of auxiliary
supply to the relay module.

The password can be changed via the serial bus
or via the MMI of the module. When the
password is to be changed via the serial bus, the
password must be opened first. The new pass-
word is written to parameter V161. The change
of the password via the MMI of the module is
carried out in register A, subregister 3, in which
case the new password is written over the old
one.

If an incorrect password is given seven times in
a row via the serial bus, the password is auto-
matically set to zero and after this it cannot be
opened via the serial bus. Now the password can
be opened only via the MMI of the module.

R = readable data
W = writable data
(P) = writing enabled with password

The measured currents and the status of the
external control signals can be read (R) with
parameters I1…I8.

When the value of parameters I6…I8 is 1, the
corresponding control inputs are energized.
