5 P40 Agile PIXIT 1 ITRODUCTIO This document specifies the protocol implementation extra information for testing (PIXIT) of the IEC interface in the P14, P14D and P94V with firmware version 57. Together with the PICS and the MICS the PIXIT forms the basis for a conformance test according to IEC The PIXIT entries contain information which is not available in the PICS, MICS, TICS documents or SCL file. 1.1 Contents of this document Each chapter specifies the PIXIT for each applicable ACSI service model as structured in IEC The Ed column indicates if the entry is applicable for IEC Edition 1 and/or Edition 2.

6 PIXIT P40 Agile 2 PIXIT FOR ASSOCIATIO MODEL ID ED Description Value / Clarification As1 1 As2 1, 2 Maximum number of clients that can set-up an association simultaneously TCP_KEEPALIVE value. The recommended range is 1..20s. 16 The default interval for TCP_KEEPALIVE messages transmitted by the relay is five (5) seconds. The TCP_KEEPALIVE messages are transmitted for a fixed period of approximately 75 seconds following the last received keep-alive response, after which time the client association will be dropped. The time-out period for aborted sockets is approximately sixty (60) seconds. For the As3 Lost connection detection time duration of this time-out period the socket resources are unavailable for new client 1, 2 association requests. A total of 100 sockets are available. As4 - Is authentication supported Transport selector As5 1, 2 As6 1, 2 As7 1, 2 As8 1, 2 As9 1, 2 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 startup time after a power supply interrupt Does this device function only as test equipment? (test equipment need not have a nonvolatile configuration; but it cannot be part of the substation automation system) <additional items> Session selector Presentation selector AP Title AE Qualifier Transport selector 0001 Session selector 0001 Presentation selector AP Title AE Qualifier Max MMS PDU size Min MMS PDU size na na 16,384 bytes 400 bytes The typical start up time of basic Ethernet services, following an interruption to the power supply is approximately 25 seconds. Full IEC services are available after an approximate start up time of 50 seconds. 4 P40Agile-PX-E-7

8 PIXIT P40 Agile ID ED Description Value / Clarification MiCOM Px40 IEDs do not have a built in range-limit for measurements, but deadbands are specified as a percentage change based on such a range. To resolve this, each measurement provides a range configuration in the data model where a minimum and maximum value can be set. Deadbands will be configured based on a percentage change of the applied measurement range. A deadband setting of zero (0) forces the measurement to follow the instantaneous value (i.e. deadbanding is disabled). For complex measurement types supporting both magnitude and angle, the deadband will only apply to the magnitude element. The CDC definition BCR_PRIV includes a Data Attribute actval whose type is IT128, according to the Standard, whereas on MMS level it is IT32 (refer Tissue 580). According to SCL the type is IT32 and according to the Data Definition in MMS the type returned for actval is IT32. 6 P40Agile-PX-E-7

This, in combination with the GOOSE IED Absent alarm, allows for GOOSE scheme problems to be easily diagnosed and dealt with automatically within scheme logic. 10 P40Agile-PX-E-7

TAL = (2 * (time to next message)) + ( Minimum Cycle Time parameter). A GOOSE IED Absent alarm is raised by the IED. If one subscribed message is not received or is syntactically incorrect, it is ignored. (If the next message is also not received or is syntactically incorrect, the TAL will be exceeded.) Gs4 1,2 What is the behaviour when a subscribed GOOSE message is out-of-order It is processed as if it were in order.

User can configure dataset members up to maximum limit GOOSE packet can hold. The capacity of Goose Packet is indicated in IED Configurator. P40Agile-PX-E-7 11

14 PIXIT P40 Agile The data received in a GOOSE message is only processed when a change in status number (stum), taken from the GOOSE message header, is detected. o validation checks are made to ensure the data has changed inline with the stum increment and it is accepted and processed as per the normal procedure given above. The data is transferred onto Boolean Virtual Inputs (made available in the Programmable Scheme Logic) when the data subscription parameters are met: Virtual Input state = True / On, when the received data value matches the Virtual Input s target value in accordance with its comparison operator. Virtual Input state = False / Off, when the received data value does not match the Virtual Input target value in accordance with its comparison operator. The following comparison operators are supported: GOOSE data value EQUALS target value GOOSE data value IS OT EQUAL TO target value GOOSE data value IS LESS THA target value GOOSE data value IS GREATER THA target value GOOSE data value is PASSED THROUGH without comparison (only applicable for binary data elements). The assignment of data values processed in received GOOSE messages is only transferred to Virtual Inputs if the quality of the data is acceptable. If the item being decoded is of a Common Data Class type (e.g. SPS) then an assignment to a quality value is automatically made (as it also forms part of the Common Data Class value). For basic data types, assignment to a quality value is manual. A value is classed as being bad quality if any of the quality flags, that are configured by the user in the IED Configurator, is asserted in the received quality value. If no quality flags have been configured, the value is always classed as good. Quantity of Virtual Inputs is product dependant refer to GosGGIO1 in MICS. For the following conditions, a Virtual Input s value will be forced to its configured default value: The publishing device is absent (e.g. no GOOSE messages are received). The received GOOSE message does not pass the validation criteria. The received GOOSE message has the Test flag set. The received GOOSE message has the dscom flag set. The default value is configured in the IED Configurator. 12 P40Agile-PX-E-7

(00) Supports 1 SBOns/SBOes control object be selected at the same time DOes: SBOes: The IED will not accept a select request from the same client when the control object is already selected. This applies to both SBO control with normal security and SBO control with enhanced security. (Tissue 334) SBOns: If the client has already successfully selected the control and a second select request is issued, the IED will return a null string which indicates a Select Response-. The failure to select the control does not affect its initial state (i.e. the control remains in a selected state). SBOes: If the client has already successfully selected the control and a second select request is issued, the IED will return the following: SelectWithValue Response- with data access error temporarily-unavailable LastApplError.Error = Operator Test ot OK LastApplError.AddCause = Command-already-inexecution The failure to select the control does not affect its initial state (i.e. the control remains in a selected state). Attempts to operate an SBO control with enhanced security will only be successful if the control number in the operate request matches the control number of the successful select request.

20 PIXIT P40 Agile If automatic extraction of Disturbance Records is required, the file operations must be performed on the dr_unextracted directory. This directory contains disturbance records that have not been downloaded from the IED by a client. A record is classed as downloaded (or extracted) when the *.dat file has been transferred. Once extracted, disturbance records are automatically removed from this directory. However it should be noted that these records are still available from the COMTRADE and dr directories. 18 P40Agile-PX-E-7
