Event Codes - ABB SPAJ 111 C User Manual

Event codes

Over the SPA bus the substation communica-
tion system can read event data of the relay
module SPCJ 1C7, e.g. start and trip events.
Event information read are printed out in the
format: time (ss.sss) and event code. The event
codes of the module are E1...E8 and E50 and
E51. Further, the communication system forms
event codes related to the data communication.
The event represented by the event codes E1...E8
can be included in or excluded from the event
reporting by writing, via the SPA bus, an event
mask (V155) to the relay module. The event
mask is a binary number coded to a decimal
number. The event codes E1...E8 are repre-
sented by the weight factors 1, 2, 4...128. The
Code Event
E1 Starting of stage I
E2 Reset of starting of stage I
E3 Tripping of stage I
E4 Reset of tripping of stage I
E5 Starting of stage I
E6 Reset of starting of stage I
E7 Tripping of stage I
E8 Reset of tripping of stage I
E50 Restarting
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 the event reporting
1 included in the event reporting
* no code number
- cannot be programmed
Note!
The codes E52...E54 are formed by the com-
munication system.
event mask is formed by multiplying the weight
factors by 0 (event not included in the report-
ing) or 1 (event included in the reporting) and
adding the weight factors so received, compare
calculation of switchgroup checksum.
The event mask can take a value within the range
0...255. The default value of the sensitive earth-
fault relay module SPCJ 1C7 is 85, which means
that all startings and trip events are included in
the reporting, but not the reset events. The
events represented by the event codes E50...E54
cannot be excluded from the reporting.
