Integrated Modular Avionics SubSystem - Description & Operations 1.1 Integrated Modular Avionics SubSystem - Description 1.1.1 General Description General Description IMA Modules The Integrated Modular Avionics (IMA) is made up of 14 Core Processing Input/Output Modules (CPIOM) and 6 Input/Output Modules (IOM). There are six types of CPIOM and one type of IOM. Each type of module is associated to a specific part number. The modules are manufactured by two different suppliers, Thales and Airbus. Thales provides CPIOM-B, -E, -F and -G types, whereas Airbus provides CPIOM-C, -D and IOM-A types.

The ADCN provides the IMA with data exchanges services. Each type of CPIOM hosts the software applications related to a specific functional area as indicated on the figure. They also provide input/output services to conventional Line Replaceable Units (LRU), which have non-AFDX interfaces. The CPIOMs manage the data transfer for their hosted functions. The IOMs manage the data transfer to/from the ADCN for those conventional LRUs not connected to CPIOMs. Each LRU uses two redundant IOMs. Released in November 20, 2018 TRAINING USE ONLY Training Use Only 6 / 95 This document shall be used in accordance with the provisions described on the front page.

NTCSS Release 2023-01 45_ATA42_Lv2&3_CAT B2_P_NOV18.pdf A400M Training Manual Integrated Modular Avionics SubSystem Description & Operations Detailed Description IOM Functions and Software The IOM is a gateway which supports the management of data transfers to and from the ADCN network, especially for the LRUs that have no connection to the ADCN. The ADCN acquisitions, processing and emissions are organized around the AFDX End System. An internal conversion function converts the AFDX data into non-AFDX data and vice versa. The IOM can manage the following types of non-AFDX inputs/outputs: - CAN - Analog (only inputs) - Discrete - ARINC 429. For some particular interfaces, the IOM also provides discrete-to-ARINC conversion. The IOM functions are supported by the module software, which is field loadable and consist of: - The Configuration Table, which provides the IOM with configuration data. - The Operational Program, which operates the module and the conversion function. The IOM does not host avionics applications.

The System BITE centralizes the failures received from the corresponding ATA system Application BITE and any other ATA system LRU. The System BITE sends the malfunction messages to the CMS and the Resource BITE. It also stores the messages in Non Volatile Memory (NVM). The CMS Interactive Mode, which is manually started from the AMAT, allows the operator to perform: - The System test and - The BITE memory dump. - The Resource BITE: It monitors and analyzes the internal failures of the IMA modules. In the case of the CPIOM, it also correlates the result of its internal monitoring with the messages received from the System BITE. The Resource BITE sends the malfunction messages to the CMS and stores them in NVM. The CMS Interactive Mode allows the operator to perform: - The Module Test and - The Resource BITE Memory Dump.

The IOMs are working by pair. It is said that the IOM-A 1, 3 and 5 are "mirror" of IOM-A 2, 4 and 6, and vice versa. In order to provide a high level of data transfer availability, any conventional LRU that exchanges data with ADCN uses both redundant “mirror” IOMs: - Any LRU receives each input signal from two mirror IOMs - Any LRU sends each output signal to two mirror IOMs, which transfer it to the ADCN.

The Radio Altimeter system is made up of two LRUs: RA 1 and RA 2. Each one dialogs through a different couple of IOMs. Any message sent by the RA 1 is transmitted through IOM-A 1 and 2, whereas any message sent by the RA 2 is transmitted through IOM-A 3 and 4. The Primary Flight Displays receive the messages twice from each RA. The Primary Flight Displays implement redundancy management logics in order to select one message and to present unique radio altitude information.

Avionics Data Communication Network SubSystem Description & Operations 2.1 Avionics Data Communication Network SubSystem - Description 2.1.1 General Description General Description General Architecture and Interfaces The ADCN is composed of two independent networks, A and B. Each network is made up of 8 AFDX switches: - Network A includes switches 1 to 8 - Network B includes switches 11 to 18. The ADCN is used to exchange operational and maintenance data between most of the aircraft computers like CPIOMs, IOMs, and LRUs with AFDX interface. For fail-safe purposes, each computer is linked simultaneously to both redundant networks. An AFDX switch has several input/output ports that are physically linked to the computers by means of the AFDX cables. The switches within one network are also interconnected by AFDX cables (not represented on the figure).

Each ADCN subscriber has an input/output interface, the AFDX End System. This is the part of the equipment that encodes and decodes data (e.g. application data) to be exchanged with other subscribers through the AFDX switches. The AFDX End System duplicates messages in transmission by sending them simultaneously on both redundant networks A and B. Two AFDX switches, one in each network, route the messages to the appropriate receivers. In reception, the AFDX End System selects one of the two messages. This duplication increases the availability of aircraft systems data. The data exchanged by the ADCN subscribers are transmitted through predefined paths within the networks so-called Virtual Links. A Virtual Link is like a unidirectional channel within the networks. The routing depends on receivers (e.g.: application(s)) the emitter wants to send data. The Virtual Link: - Carries the data - Has a unique identification - Is sent by one transmitter only - Is received by one or several subscribers in receive mode - Is routed over both networks A and B through a specific path. Each ADCN subscriber can support several Virtual Links in transmit and receive modes.

The Network BITE Function (NBF), hosted by the NSS, is dedicated to fault isolation and reporting. It is a piece of ADCN software that provides network failure messages to the CMS. The NBF collects BITE information from all AFDX End Systems and AFDX switches. It also allows the CMS interactive test. Each AFDX switch has a fault discrete output connected to the FWS in order to determine the overall status of the ADCN. This information is used to trigger the failure alerts to the flight crew. The AFDX switches host field loadable software. For maintenance, the DLCS provides the software uploading capability. The data loading function is only enabled when the aircraft is on ground. The AFDX switches compute the ground condition from the discrete input signals: - “Weight-on-wheels” from the landing gear system - “Engines off” from the engine master levers.

Each AFDX switch has a switching function, which provides inputs and outputs to other switches and ADCN subscribers. This function receives the Virtual Link coming from one emitter and routes it to the appropriate output port(s) based on the Configuration Table. The Operational Program is another piece of software that operates the AFDX switch. Both, the Configuration Table and the Operational Program, are field loadable. The discrete inputs/outputs provide pin programming and discrete signals exchanges with other aircraft systems.
