Event codes
When the voltage regulating module SPCU
1D50 is connected to a control data communi-
cator over the SPA bus, the module generates
events in the format: time, text and event code,
spontaneously to the control data communica-
tion. The text is defined by the user.
Most of the events can be included in or ex-
cluded from the event reporting by writing an
event mask number (V155…V159) to the mod-
ule. The parameters of the event mask are pre-
sented in the tables below.
The event mask is a binary number given in the
form of a decimal number. The events E1…
E33 are represented by the weighting factors 1,
2, 4…128. The event mask number is obtained
by multiplying the above weighting factors by
either 0 (event report excluded) or by 1 (event
report included). and then adding the products
received. The event mask numbers are calcu-
lated in the same way as the checksums of the
switchgroups.
The events E50…E54 cannot be excluded from
the event reporting.
At a maximum eight events can be stored in the
event buffer. If a ninth event message is received,
the code E51 is recorded in the buffer. The
buffer and the code E51 are reset by giving the
parameter WC the value 0.
The event codes E52…E54 are generated by the
control data communicator (e.g. SACO 100M,
SRIO 1000M, etc.).
More information about the SPA bus commu-
nication is given in the manual "SPA Bus Com-
munication Protocol", 34 SPACOM 2EN1.
