Status information
All the status information relating to binary input and output signals, internal
signals (single-point indications - SPI) and switchgear positions (double-point
indications - DPI) that are configured in REB500 for transfer via IEC60870-5-103,
but are not covered by the compatible part of the IEC recommendation, are
transferred as generic data. An entry is made in the table for every event configured
using HMI500 or REBCON for transfer via IEC 60870-5-103. Since there can be
more events per type (SPI or DPI) than the maximum number of entries a group
can have (255), the system reserves additional groups as necessary. By this means,
up to 1020 events per event type can be defined in the generic part.
