Version: 2.06 3 General The AQ-S255 bay control unit is a member of the AQ-200 product line. The hardware and software are modular: the hardware modules are assembled and configured according to the application's I/O requirements and the software determines the available functions. This manual describes the specific application of the AQ-S255 bay control IED.
Instruction manual Version: 2.06 5 Functions 5.1 Functions included in AQ-S255 The AQ-S255 bay control IED includes the following functions as well as the number of stages in those functions. Table. 5.1 - 3. Protection functions of AQ-S255. Name ANSI...

The recorder is configured by using the setting tool software or relay HMI, and the results are analyzed with the AQviewer software (is automatically downloaded and installed with AQtivate). Registered users can download the latest tools from the Arcteq website (arcteq.fi./downloads/).
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) •...
→ AQ-200 series → Resources). 6.1.5 GOOSE Arcteq relays support both GOOSE publisher and GOOSE subscriber. GOOSE subscriber is enabled with the "GOOSE subscriber enable" parameter at Communication → Protocols → IEC 61850/ GOOSE. The GOOSE inputs are configured using either the local HMI or the AQtivate software.
(slave) station. The IEC 103 protocol can be selected for the serial ports that are available in the device. A primary (master) station can then communicate with the Arcteq device and receive information by polling from the slave device. The transfer of disturbance recordings is not supported.
