- 2. Description of break-down 2.1. Introduction The system has been broken down to give a modular structure based upon the fcllowing criteria:
- the standard functions described in document [6]
- the physical break down of the software in a DU :
-system software
-application software
- the development of modules common to the LPU and the DU
- the modularity and maintenance of the software Certain modules are duplicated, as they are used both by the system software and the application software. This approach avoids the use of function call mechanisms between the system and application software and makes it possible to develop the application software independently from the system software.
2.2. Modular break-down The following diagram illustrates the architecture of the DU software.
It can be seen that the saftware is broken down into modules :
(1)
Initialization of system software and maintenance mode : controls all the initialization phases of the system (hardware, software modules) and manages the sequencing of the software's actions in maintenance mode.
(2)
Management of interrupts controls the installation of hardware interrupt drivers and redirects the interrupts to the software modules concemed.
Management of time : controls the real-time clock and the timers.
Management of communications : initializes and controls the asynchrorious links and manages the JBUS / MODBUS protocol of the links. Certain functao of this module are common to the LPU and the DU, described in document [9]
These 3 modules are grouped together in a single unit.
(3)
Supervision of Commands : supervises the execution of all commands. The functions of this module are common to the LPU and DU. They are described in document [9}.
(4)
Management of commands in maintenance mode : controls the execution of DU commands in maintenance mode. T1 e ccmmands common to the LPU and DIJ 3
are described in document [9].

(alarms, malfunctions, etc.) in the visual or auditory outputs (relays, LEDs, lamps, buzzers) and the updating of the status of the DU.
(10)
Management of IIO and broadcasting : controls broadcasting of virtual input and data (of whatever sort) to the slaves.
E (11)
Management of control command : handles the management of the control command of the LPU (machine)
(12) Management of external commands : controls the local or extemal digital output of the DU on a DU belonging to the network.
(13) Management of slave information : controls the routine interrogation (or subsequent to a re-initialization) of slave parameters.
(14) Management of Keyboard : manages keyboard actions.
(15)
Management of analogue output : manages the analogue output of the DU.
(16)
Management of logs : manages the storage of the one minute averages of the measurements of all the primary channels of the slave LPUs associated with the DU.
(17)
Management of state machines : manages the sequencing of the state machines which make up the application software as well as the use of signals,for the synchronization of these machines.
(18)
Management of nehuork commands : manages the asynchronous execution of local network commands in maintenance mode and in normal mode.
(19) Management of display manages the display of graphic objects in maintenance mode and in aormal mode.

Radiation :'Jonitodng System DC Genr.CJ Sonwam Design Descriphon p 12 2.2.1.1. Initialization of system software and maintenance mode This module consists r'f 3 main functions :
- a function Si mitializing the system software
- a function describing processing in maintenance mode
- a function describing the main loop of the software.
When the software is started up, the function Generallnit is called. When this has been correctly executed, Main makes a call to the function Mainloop which describes the main loop of the software. If an err 7rjustifying the change-over to maintenance mode is detected, Mairitoop altere the no mal operation of the DU to operation in maintenance r
mode managed by the function MaintenanceCycle. When a retum command from the I
maintenance mode is triggered by the opt ator Mainloop switches the operation of the DU back to normal mode.
The module belongs entirely to the system software.
Generallnit :
This function forms part of the system software. It handles the initialization of the system software. Its algorithm is as follows :
Initialize the laterrupt divers.
initialize the parameter table (RAZ of statuses and the result area, copy the e
parameters into the result area, initiailze control words and update the information area on the unit).
Initialize the real-time clock.
Initialize the display module.
Carry out a complete test of the RAM memory.
Carry out a complete test of the peripheral hardware, relays, buzzer and the lamps.
Test the program memory of the systentsoftware by checksum comparison.
6 Test the prop am memory of the application software by checksum comparison.
Set the DU to normal mode.
Test the coherence of the critical parameters of the TP.
Initialize the interrupts and communications.
Initialize the network command management module.
Initialize the reai-time clock.
Record the start-up event of the DU.
If the DU is of the type Normal or Router Check the topology of the sub-network :
Test the correct number of slaves connected.
Test the type of slaves connected.
Update the slave parameters area of the TP.
IF the DU is faulty Switch to mode maintenance.

EP Radiation Monitoring System DU GenersiSonware Design Descripuon p 13 Initialize the management module for maintenance mode commands.
Initialize the application software.
Start the main loop.
The call to the initialization function of the application software is made to a fixed address corresponding to the entry point of the application software which is stored in flash memory.
l This call b 0,xed address makes it possible to effectively separate the system and i
application software. Indeed, as the system and application software are separately linked, the address of the entry point of the application software is not known to the system software when the link is made. The entry point of the application software is therefore pro-set to a constant address.
The second function is the sequencing function for maintenance mode actions.
MaintenanceCycle
. Updating the current DU information..(date, time, supply voltages, temperature, etc.).
. Managing the watchdog.
. Executing the maintenance mode commands.
. Processing the queued enquiries (cf. communication module).
The actions conceming the management of the watchdog and the execution of commands are specified in the description of the corresponding modules.
The third function, called MainLoop, is the main loop of the software, its algorithm is as follows :
DO WHILE Control Communication IF the DU is in normal mode THEN Operate in normal mode ELSE Operate in maintenance mode END IF END WHILE The normal mode processing function forms part of the application software. It is called via a variable common to the 2 sets of software containing the address of the function NormalCycle and initialized by the initialization function of the application software (cf.
initialization module of the application software).
This module also contains the functions for processing interrupts automatically generated by the processor (bus error, address error, etc.) as well as the function for processing the non-maskable interrupt, NMI.

2.2.1.2 Management of interrupts, time and communications This module belongs entirely to the system software.
l The LDU uses interrupts in the following cases:
. sending / receiving characters on the 4 ceries links
. detection of frame end for the 4 series links
. real-time clock (10 ms)
To do this it makes use of the following peripherals:
. DUART 68681 1 : manages the RS232C and RS485 master links and Powerfnil.
. DUART 686812 : manages the 2 RS485 slave links and the real-time clock.
. PTM 68401 : manages the frame ends for the RS232C and RS485 master links.
. PTM 6840 2 : manages the frame ends for the RS485 slave links.
The interrupt drivers (entry points of the IT programs) are described in the hardware interfaces, PTM and DUART(described in document [9]).
They are installed by the function 'Generallnit" of the Initialization module.
Note :
The interrupt levels used are the following :
level allocation 1(lowest priority)
PTM1 2
PTM 2 3
BUS G96 4
BUS G96 or HTR 5
DUART2 6
DUART1 7
either :
- Watchdog or
- Supply fault or
- BUS G96 The DU communication management module relias on the hardware interfaces P,TM and DUART and also on the slave communication management module common to the LPU and DU. All these modules referred to are described in document (9).

. Initialize the counters to 0.
. Initialize the shared variables (state of slave links (OK or not OK), table of enquiries for the master link, state of the master link (free or busy)).
. Initialize the common variables FirstPollingWithSuccess which indicates the first polling successfully carried out for this slave.
The character sending and receiving functions form a set of 6 functions.
As the reading functions for the 3 links are identical, they are grouped together as one, with a parameter indicating the communication channel used.
The same appi;es to the writing functions.
A sending buffer and a receiving buffer are associated with each communication channel.
The size of the buffers is equal to the size of the longest frame which can be received or sent (JBUS / MODBUS standard) plus a certain margin.
Certain dedicated functions of the RS485 links can cause changes to these functions.
The funcbon of sending a frame is the same for the 2 slave links :
m.
- Write 8taveFrame
. Transfer the frame to be sent into the transmission buffer of the selected channel.
. Initialize the current character and the number of characters to be sent.
. Validate the transmission by interrupL The buffer to be sent will have first been structured in accordance with the JBdS /
MODBUS standard (calculation of CRC, etc.).

A data area containing the following information will be associated with each enquiry:
. type of enquirer : local, RS4851, RS4852 or RS232C.
. state of the enquiry : " Queued' or " Processed" (fault).
ID of the slave to which this enquity is addressed.

At the time of recording, the enquiry is stored and the status is initialized to "OK".
These enquiries are stored in the memory area common to the 2 sets of software.
A status word for the link makes it possible to store whether the link is " Free" or, in the opposite case, the type of the enquirer.
At the end of processing, the enquiry is set to the state " Processed' and the status is updated.

g.aanmanensMGP Radiation Monitoring System Du General Software Design Description p 24 Only enquiries of the type local require the storage of the response and the status of this response. Responser. to network enquiries are sent back directly on the enquirer slave link without storage.
Explana ons on the IT real-time processing regardirig communication :
r The value of (ne time-out will have to be adjustable v/ith parameters depending on the position of the DU on the network. Time-outs increase progressively the further one moves from the system terminals in the architecture of the network.
In fact, the time-out must take account of the time required for routing enquiries and responses by the nodes of the network.
This is essential to ensure that a given master'does not
- quit' with a time-out before the router or routers located between this master and the sisve addressed.
This progressive time-out ensures 9at if the master link is
- Occupied' on a DU subsequent to an enquiry on a slave channel, this DU will receive no enquiry on this slave channel until the master link is released (by receiving the expected response or by the detection of a time-out).
Furthermore the time-out will need to take into account the fact that a maximum of 3 enquiries can be queued simultaneously and must therefore multiply by 3 the waiting time of the response (enquiries on the RS485 always have priority).
The duration of broadcasting is 50 ms in accordance with the JBUS / MODBUS specification (taking into account the time for sending the frame).
In order not to overload the IT real-time processing, no call is made to the function for processing queued enquines after the link has been set to " Free'.
This call should be made, routinely, in the main loop of the software.
Important :
Access to the master link must only be granie'hto the 4 possible enquirers on the basis of mutual exclusion.
For this raason, the critical sections are embedded in unified processing functions at the start and end.
These functions will prohibit or authorize interruptions of the communication (slave frame end, master frame end and HTR processing).
The processing time between the start and end of unified processing must,not exceed the period of the real-timo clock (10 ms in principic).

On the one hand it detects the occurrence of an alarm or of a fault by producing synchronization t'gnals for the other processes and updating the status of the r,U and, on the other hand, it signals alarms or faults by means of the LEDs, lamps or the
- buzzer, it operates in the same way whatever the type of the DU.
interface.1 This module makes use of the following signals :
SLAVE _ POLLED : cf. polling module.
END OF_ POLLING : cf. polling module, it generates the following signals :
HIGHER _LPU_ ALARM : Indicates that a new alarm has just been detected (starm of a higher level to the current level or new measurement channel in alarm state). This signal is accompanied by a parameter indicating the unit and the channel in alarm state as well as the alarm level.
INTERNAL _ FAULT : Indicates the occurrence of an intomal fault in the DU (no parameter).
SLAVE _ INTERNAL _ FAULT : Indicates the occurrence of an intamal fault in a slave of the DU (DU or LPU). This signal is accompanied by a parameter indicating the faulty unit.
SLAVE _ OPERATING _ FAULT : Indicates the occurrence of a processing fault by a slave of the DU (DU or LPU) or the switching of a slave to maintenance mode or degraded mode. This signal is accompanied by a parameter indicating the faulty unit.
The functions initAlarm, EndAlarm and AlarmDetection make it possible to initialize, terminate and execute the module.
The function Buzz 9 tack allows acknowledgment of the sound alarm.
The function BuzzerCmd allows control of the buzzer.

2.2.1.12. Management of extemal cota.3 ands l
This module forms part of the application t are.
Heminder.
An extemal command makes it possible to:
. pre-eet a digital output in the active state (in manual mode). If the output was in automatic modo it switches to manual mode.
. or to pre-set a digital output in the inactive state (in manual mode). if the output was in automatic mode it switches to manual mode.
. or to pre-set the management of the digital output in automatic mode, in which case the value of the digital output is not affected.
This module manages the processing of commands on the local digital output of the DU or on the output of any DU which belongs to the network and which accepts commands from outside.
Each DU may either be of the type sender or of the type receiver of extemal commands, and this type is specified by a parameter, in the event of extem;l commands they switch from one sub-network to another by means of a slave LPU which handles the transfer of commands.
DUs of the type sender transmit their commands to the LPU which receives them, while receiver type DUs take account of the commands received by interrogation of ths LPU.
Interfacal This module does not make use of any signal but generates the following signal :
CMD_SCR_MODIF : this signal is set after the modification of one of the labels in the extemal commands. The visual display module makes use of it to initiate the refreshing of the extemal command screen, The functions initExtOutCmd, EndExtOutCmd and UpdateXCommand make it possible to initialize, terminate and execute the module.
The functions WriteOtCmd make it possible to control the local digital output.
The updating of localinput/ output consists of analyzing a command word and checking the digital output accordingly. This word command may have two sources:
. The command screen which allows the operator to directly modify this state from the keyboard of the DU.
. The polling of a slave which sets its command word differently from its status word to indicate a change of state.

T Radiation Monltodng System DU General Software Design Description p 49 Three configurations are possible :
The DU is autonomous, and the power outputs are controf ed locally, in fact the control screen makes it possible to directly control the outp 4. Ths atus in the x
reading area is updated at the same time. A master can also wntrol the output using the writable command area and the readable status area.
The DU can receive extemal commands from another DU connected as a slave. In this case the status is regularly broadcast to the slave, which can display it on its screen. In the event of voluntary modification of the output, the slave DU provides the command which is regularly read by the commanded DU in the reading area.
The DU ryeives extemal commands by means of one of its slave LPUs, in this case, tM i. ender DU transmits its commands on the t. pus which systematically copy the commands and statuses of the writing area to the reading area and enakes the information available to the commanded DU.

On the one hand it performs the polling.of the slave parameters, periodically (period in TP) or after a reset, and generates the synchronization signals to the other processes.
The slave parameters polled are the name of the unit (@10) and the measurement channel parameters for LPUs (from the @800). This module performs the updating of the slave parameter area of its own TP (@1800-2263) for DUs of the types normal or router.
For DUs of the type slave n'o reading or updating of the slave parameter area of the TP is performed. Any updating is detected only by a DU master of the area Slave parameters.
Interface :
This module generates the following signals :
SLAVE _UNITNAME_MODIF : Indicates that the name of the unit, the identity of which is passed as a parameter has been modified.
SLAVE _CHANNELPARAMS_MODIF : Indicates that the measurement channel parameters have been modified for the unit, the identity and the channel number of which are passed as parameters.
The functions initinfos Endinfos and InfosPolling make it possible to initialize, terminate and execute the module.

i This representation, branches above and action below, will be maintained for the remainder of the document.
To synchronize these different machines, a Signal type mechanism is used.
The signals are managed by the functions :
SetSignal : allows a signal to be set and a parameter to be associated with it. The setting of a signal reinitializes all the stored acknowledgments of this signal.
TestSignal : allows the state of a signal to be tested (set or not set) and the signal parameter to be retrieved. If the test is positive (signal set), the call to the function is stored so that the next call to TestSignal is negative if this signal has not been reset in the meantime.
RosetSignal : allows a signal to be reset and to reinitialize all the stored acknowledgments of this signal.
The signals are never addressed to a particular destination but are set for all the e
processes managed by the system.
The maximum number of signals managed by the system is a system parameter.

1 l J MGP ananann Radiation Monitoring System Du General software Design Description p 61 The display in the graphic objects virtual screen is managed by an object-oriented hierarchical structure using the mechanisms of inheritance and polymorphism.
All of this is based on a basic graphic object GRAPH, OBJ with the following methods :
Display : display of the object in X and Y (X and Y may be negative). This method is virtual.
SetRasterOp : setting of an operator for combination with the background.
All the objects possess a creator called Newxxxxx (ex: NewGraphObj for objects of the type GRAPH _OBJ) arsi a virtual deletar called Delete.
The objects available are the following:
BITMAP : design of a monochrome image. The buffer containing the bitmap to be displayed must be organized in the following manner :
- 0,0 is the top left hand comer of the image.
- The bytes which make up the image are in the format MSB - LSB.
- The buffer contains firstly all the bytes for the first column, then the second, etc...
- The bytes for the last column are left justified and padded with zeros if the width of the image is not a multiple of 8.
STRING : design of character string.
The module includes several fonts of character"s'which may be of different sizes. These fonts contain the bitmaps for each of their characters and are resident in program memori.
The fonts can be generated and modified by means of the font editor FONTEDIT (tool specially developed for this purpose).
The standard font is 6X10 pixels in size (10 characters by 24 rows).
The standard character set includes the standard ASCll characters beiween 32 and 127 and certain specially defined characters (semi-graphic characters, superscripts, etc.).
LINE :line drewing.
The lines may be of different thickness and length. It is also possible to display dotted lines. The orientation of the drawing is vertical or horizontal (no diagonal lines).
RECT : rectangle drawing.
The rectangles may be of different thickness, width and length. They can also be drawn with datted lines.
FRECT : filling in of a rectangle.
Different pattems can be used for filling in: completely dark, completely light or with half-tones (1/4,1/3,1/2 or 2/3).

This module can be broken down into 2 parts :
. Self tests common to the LPU and the DU :
They are described in document [9).
. Self-tests soecific to the DU :
On each run through the main loop, the function StatutslightTest is used to test that the 3 lamps are operating correctly. This test is performed with the lamp off. The state of the lamps is restored after the test.
A test of the buzzer will be performed periodically. This test only works when the buzzer is c,ommanded. This function is performeri in the ' alarm signalling".
The 5 relay outputs associated to the LEDs are tested periodically for proper functioning, hcwever only the current controlled state is tested (position open ci closed at the time of th. test).
For the relay c, 4tputs,2 bits indicate the relay's position (open or closed). This functio;.
is performed in the ' Alarm signalling" module.
The analog inputs / outputs are tested periodically for proper functioning; a bit indicates the correct conversion.
1 This test is automatically integrated by th3 functions of the module IOTOR which allow 2 digital test inputs corresponding to the tests for the working and resting positions to be associated with a digital output.

3.t::-:J:-. of dependr < ei 3.1. Dependency between wodules
- The diagram in the section
- Modular break down" clearly illustrates the dependency between the different software modules.
This diagram describes the architecture of the software as well as the hierarchical
- elationships within the modules from which it is formed.
Furthermore, it clearly ids,iifles the modules common to the 2 sets of software.
On th!3 diagram, the software modules sie organized like bricks. Each brick (a software module) is built on one or more bricks belonging to a loiver level (the modules which they make use of).
The organization is structured vary hierarchically. In principle, a module is only seen by modules built on it (on higher levels) and itself only uses the modules on which it is built (on lower levels) or, in certain cases, the modules which are beside it..
The modules grouped together at the bottom of the diagram (Hardware interface, Event
. Management and Tool-box Management, Network Command Management and Display Menagement) are used by all the other modules.
The system and application software components are clearly distinguished by differe-'
colors.
No module contains a system part and an application part at the same time.
The functions accessible to the 2 sets of software are, in general, grouped in modules common to the 2 sets of software (identical modules but duplicated in memory).
Some functions of certain modules are, however, accessible to the 2 sets of software witnout being duplicated. A mechanism of access by pointer to the function enables them to be called.
The unctions in question are N communication functions WriteMasterFrame and ScheduleMasterlink and the normal mode sequencing function NormalCycle.
The initializabo' function of the application software Specificinit is the only function situated in memory at a fixed address.
