IEC 61850 Object Changes
The SEL-421-0, -1, -2, -3 implementation of the IEC 61850 protocol suite differs
slightly from the SEL-421-4, -5 implementation. Tabl e B.1 4 lists the main func-
tional changes between the two.
Default datasets may be used for MMS Reports or for GOOSE message transmis-
sion. Table B.15 lists the default dataset changes in the new ICD file version.
Note that the contents of any dataset may be modified via
ACSELERATOR Archi-
tect SEL-5032 Software.
Most of the Logical Nodes and Attributes remain the same between the two
implementations. Table B.16 lists the mapping changes in the new ICD file.

is within 500 ms.
