4.5.2 Status information
GUID-49587D6A-D1F8-43AD-ACBD-AEB285A3C396 v1
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.
