Event codes

14
Over the SPA serial bus the data communication
equipment reads event data, for instance, start
and trip information, produced by the relay
module SPCS 3C4. On request the relay mod-
ule transmits its event data in the format: time
(ss.sss) and event code. The event codes of the
module are E1...E8, E50 and E51. In addition
the data communication equipment can form
event codes related to the data communica-
tion.
The codes E1...E8 and the events represented by
these can be included in or excluded from the
event reporting by writing, over the SPA bus, a
so called event mask (V155) to the module. The
event mask is a binary number coded to a
decimal number. The event codes E1...E8 are
Code Event
E1 Start of stage Iϕ>
E2 Reset of start of stage Iϕ>
E3 Tripping of stage Iϕ>
E4 Reset of tripping of stage Iϕ>
E5 Start of stage Iϕ>>
E6 Reset of start of stage Iϕ>>
E7 Tripping of Iϕ>>-stage
E8 Reset of tripping of stage Iϕ>>
E50 Restart
E51 Overflow of event register
E52 Temporary disturbance in data communication
E53 No response from the module over the data
communication
E54 The module responds again over the data
communication
0 not included in event reporting
1 included in event reporting
* no code number
- cannot be programmed
represented by the numbers 1, 2, 4...128. The
event mask is formed by multiplying above
numbers by 0, event not included in reporting,
or 1, event included in reporting, and by adding
the products thus received, compare switch-
group checksum calculation.
The event mask may take any value from 0 to
255. The default value of the directional neutral
overcurrent module is 85, which means that the
starts and trips, but no resettings, are included in
the reporting. The codes E50...E54 and the
events represented by these cannot be excluded
from the reporting.

current module SPCS 3C4:

In the SPACOM system the event codes
E52...E54 are formed by the data communi-
cation equipment.
