The most crucial changes in IEC 61850-8-1 Edition 2 compared to the Edition 1 are:

• support of Gigabit Ethernet
• link layer redundancy
• extension of the length of the object reference: ObjectReference maps to a variable length MMS visible string with a maximum length of 129 octets.
• extension of the reason for inclusion type for comprehensive logging
• mapping of the tracking services
• a second mapping of the objectReference when used in the tracking services, or as linking
• extension of the AdditionalCause enumeration
• simulation of GOOSE telegram
• fixed-length encoded GOOSE message
• removal of the SCL Control Block
• mappings of ACSI service error codes and ISO 9506 error codes have changed. One change that should be noted is the change in usage of object-undefined. The object-undefined code has been replaced by object-non-existent in many responses.
