2 Introduction This document specifies the protocol implementation extra information for testing (PIXIT) of the IEC interface in SEL-2411 with firmware version R310. Together with the PICS and the MICS the PIXIT forms the basis for a conformance test according to IEC Contents of this document Each chapter specifies the PIXIT for each applicable ACSI service model as structured in IEC PIXIT for Association model Maximum number of clients that can set-up an association simultaneously TCP_KEEPALIVE value Lost connection detection time Is authentication supported What association parameters are necessary for successful association If association parameters are necessary for association, describe the correct values e.g. What is the maximum and minimum MMS PDU size What is the maximum start up time after a power supply interrupt seconds 1 20 seconds Transport selector Session selector Presentation selector AP Title AE Qualifier Transport selector 0001 Session selector 0001 Presentation selector AP Title A AE Qualifier A Max MMS PDU size bytes Min MMS PDU size Approximately 90 seconds Rev. 2.3 Schweitzer Engineering Laboratories, Inc.

4 PIXIT for Data set model What is the maximum number of data elements in one data set (compare ICD setting) How many persistent data sets can be created by one or more clients How many non-persistent data sets can be created by one or more clients 500 FCDAs Dynamic data set creation is not supported Dynamic data set creation is not supported PIXIT for Reporting model The supported trigger conditions are (compare PICS) integrity data change quality change data update general interrogation The supported optional fields are sequence-number report-time-stamp reason-for-inclusion data-set-name data-reference buffer-overflow entryid conf-rev segmentation Can the server send segmented reports Mechanism on second internal data change Send report immediately notification of the same analogue data value within buffer period (Compare IEC $ ) Multi client URCB approach Each URCB is visible to one client only (compare IEC $14.2.1) What is the format of EntryID OctetString8 What is the buffer size for each BRCB or how 120 Kbytes many reports can be buffered Pre-configured RCB attributes that cannot be changed online when RptEna = FALSE cbame datset (see also the ICD report settings) May the reported data set contain: - structured data objects? - data attributes? What is the scan cycle for binary events? Is this fixed, configurable 0.5 seconds Fixed Does the device support to pre-assign a RCB to a specific client in the SCL BRCB enable behavior with respect to negotiated PDU size If a client negotiated a smaller PDU size than the last client that enabled a BRCB, that client will not be able to enable the BRCB Rev. 2.3 Schweitzer Engineering Laboratories, Inc.

5 PIXIT for Generic substation events model What elements of a subscribed GOOSE header are checked to decide the message is valid and the alldata values are accepted? If yes, describe the conditions. ote: the VLA tag may be removed by a ethernet switch and should not be checked Can the test flag in the published GOOSE be turned on / off What is the behaviour when the GOOSE publish configuration is incorrect When is a subscribed GOOSE marked as lost? (TAL = time allowed to live value from the last received GOOSE message) What is the behaviour when one or more subscribed GOOSE messages isn t received or syntactically incorrect (missing GOOSE) What is the behaviour when a subscribed GOOSE message is out-of-order What is the behaviour when a subscribed GOOSE message is duplicated Does the device subscribe to GOOSE messages with/without the VLA tag? May the GOOSE data set contain: - structured data objects (FCD)? - timestamp data attributes? ote: data attributes (FCDA) is mandatory Published FCD supported common data classes / data types are Subscribed FCD supported common data classes / data types are source MAC address destination MAC address Ethertype = 0x88B8 APPID gocbref timeallowedtolive datset goid t stum squm test alldata accepted if false confrev ndscom alldata accepted if false numdatsetentries The whole configuration fails and no GOOSE messages are transmitted Message does not arrive prior to TAL. If a GOOSE message exceeds the TAL, the IED will set a TAL error and wait for the next message. A TAL error will be set for each subscription that no messages have been received An out-of-sequence error is set for the subscription but the message is still processed An out-of-sequence error is set for the subscription but the message is still processed, with the VLA tag, without the VLA tag Subscribed Published LPL, DPL, IC, IS, SPS, SPC, MV, CMV, WE, and DEL All CDCs except these: HMV, HWE, HDEL, and CSD Rev. 2.3 Schweitzer Engineering Laboratories, Inc.

6 What is the slow retransmission time? Is it fixed or configurable? What is the minimum supported retransmission time? What is the maximum supported retransmission time? Is it fixed or configurable? Can the Goose publish be turned on / off by using SetGoCBValues(GoEna) What is the stum and squm of the initial GOOSE message? TAL = Time Allowed to Live 1000 mseconds with TAL = 2000 Configurable in CID file. 1) 10 mseconds with TAL = 30 2) 20 mseconds with TAL = 60 3) 40 mseconds with TAL = 120 4) 80 mseconds with TAL = 240 5) 160 mseconds with TAL = 480 6) 320 mseconds with TAL = 960, etc The TAL is twice the retransmission time at the maximum retransmission interval. This retransmission curve is fixed. Enabling and disabling of GOOSE is done via IED configuration. stum = 1 and squm = 0 PIXIT for Control model What control models are supported (compare PICS) Is the control model fixed, configurable and/or online changeable? Is TimeActivatedOperate supported Is operate-many supported Will the DUT activate the control output when the test attribute is set in the SelectWithValue and/or Operate request (when test procedure Ctl2 is applicable) What are the conditions for the time (T) attribute in the SelectWithValue and/or Operate request Is pulse configuration supported status-only direct-with-normal-security sbo-with-normal-security direct-with-enhanced-security sbo-with-enhanced-security Configurable in the CID file DUT accepts the control command but does not actually execute it to cause a status change DUT ignores the time value and execute the command as usual Rev. 2.3 Schweitzer Engineering Laboratories, Inc. Page 6

7 What is the behaviour of the DUT when the check conditions are set synchrocheck interlock-check DUT ignores the check value and always perform the check. Is this behaviour fixed, configurable, online changeable? What additional cause diagnosis are supported How to force a test-not-ok respond with SelectWithValue request? How to force a test-not-ok respond with Select request? How to force a test-not-ok respond with Operate request? Which origin categories are supported? 0 8 What happens if the orcat value is not supported? Does the IED accept a SelectWithValue/Operate with the same ctlval as the current status value? Does the IED accept a select/operate on the same control object from 2 different clients at the same time? This behavior is fixed. Blocked-by-switching-hierarchy Select-failed Invalid-position Position-reached Parameter-change-in-execution Step-limit Blocked-by-Mode Blocked-by-process Blocked-by-interlocking Blocked-by-synchrocheck Command-already-in-execution Blocked-by-health 1-of-n-control Abortion-by-cancel Time-limit-over Abortion-by-trip Object-not-selected Write a single attribute instead of the entire SBOw structure A DOns: SBOns: not supported DOes: SBOes: Write a single attribute instead of the entire Oper structure If an orcat value is not supported, either because it is disabled in the CID file or is out-of-range, a LastApplError with an AddCause of Blocked-by-process is reported DOns: SBOns: DOes: SBOes: DOns: SBOns: DOes: SBOes: Rev. 2.3 Schweitzer Engineering Laboratories, Inc.

8 Does the IED accept a Select/SelectWithValue from the same client when the control object is already selected (tissue 334) For SBOes, is the internal validation performed during the SelectWithValue and/or Operate step? Can a control operation be blocked by Mod=Off or Blocked Does the IED support local / remote operation? Does the IED send an InformationReport with LastApplError as part of the Operate responsefor control with normal security? SBOns: A SBOes: SelectWithValue and Operate SBOns: A DOns: PIXIT for Time and time synchronisation model What quality bits are supported (may be set by the IED) Describe the behaviour when the time synchronization signal/messages are lost When is the time quality bit "ClockFailure" set? When is the time quality bit "Clock not synchronised set? Is the timestamp of a binary event adjusted to the configured scan cycle? Does the device support time zone and daylight saving? Which attributes of the STP response packet are validated? LeapSecondsKnown (always set) ClockFailure ClockotSynchronized The IED sets ClockotSynchronized The IED sets ClockFailure when the relay is in a Disabled state The IED sets ClockotSynchronized when there is a loss of STP or IRIG time synchronization Leap indicator not equal to 3? Mode is equal to SERVER OriginateTimestamp is equal to value sent by the STP client as Transmit Timestamp RX/TX timestamp fields are checked for reasonableness STP version 3 and/or 4 other (describe) Rev. 2.3 Schweitzer Engineering Laboratories, Inc.
