Serial Communication Parameters - ABB SPAU 140 C User Manual And Technical Description

Serial
communication
parameters
Event codes
When the synchro-check relay module SPCU
3D45 is connected to a data communicator over
the SPA bus, the module will generate event
markings that can be printed out, for instance,
on a printer or transmitted to higher system lev-
els via the serial bus. The events are printed out
in the format: time, text and event code. The
event text is written by the user.
An event to be communicated, is marked with
the multiplier 1. If the event is to be excluded
the multiplier is 0. The event mask is formed
by the sum of the weighting coefficients of all
the events to be communicated.
The synchro-check and voltage-check functions
of stage 1 and 2 are monitored by codes E1...E6
and E7...E12, respectively, and the events rep-
resenting these can be included in or excluded
from the event reporting by writing an event
masks V155 and V156 for the module. The
event masks may have a value within the range
0...63. The default value of the synchro-check
relay module is 36 for V155 and V156, which
means that all closing operations of the sepa-
rate stages are included in the event reporting.
The status of the input signals is monitored by
codes E13...E20 and the events representing
these can be included in or excluded from the
event reporting by writing the required value to
an event mask V158. The event mask may have
a value within the range 0...255 and the default
value of the relay module is 0. This means that

no operations of the input signals are included
in the event reporting.
The status of the output signals is monitored
by codes E21...E26 and the events representing
these can be included in or excluded from the
event reporting by writing an event mask V157
to the relay module. The event mask may have
a value within the range 0...63 and the default
value of the relay module is 63. Thus, all opera-
tions of the output signals and status changes
are included in the event reporting.
The event codes E50...E54 and the events rep-
resented by these cannot be excluded from the
event reporting. The event codes E52...E54 are
generated by the data communicator used, for
example, SACO 100M, SRIO 1000M, etc.
The synchro-check relay module has its own
event register where all events are recorded in
operating order. The memory is capable of stor-
ing up to eight events. When the ninth event
occurs the code E51 is recorded in the event
register, thus, reporting an overflow in the event
register. The event register can be cleared over
the serial communication bus by writing the
value 0 to the serial communication parameter
C (resetting of module state data).
Detailed information about the serial commu-
nication over the SPA bus is given in the docu-
ment "SPA bus communication protocol",
Document No. 34 SPACOM 2 EN1.
