 IEC61850. AQ-21x frame units support Edition 1 of IEC 61850.

AQ-25x frame units support both Edition 1 and 2 of IEC61850. The following services are supported by

IEC 61850 in Arcteq devices:

• Up to six data sets (predefined data sets can be edited with the IEC 61850 tool in AQtivate)
• Report Control Blocks (both buffered and unbuffered reporting)
• Control ('Direct operate with normal security’, ’Select before operate with normal

security, ’Direct with enhanced security’ and ’Select before operate with enhanced

sequrity’ control sequences)

• Disturbance recording file transfer
• GOOSE
• Time synchronization

The device's current IEC 61850 setup can be viewed and edited with the IEC61850 tool (
