BC / RT / MT Operation
Each channel may be independently programmed for BC, RT, or RT/MT mode. This option makes use of the ACL's APOORVA IP core to provide full support for all modes of operation. When used with ACL's APOORVA IP core, 4K words of memory is available for message preparation and double buffering etc.
BC mode includes advanced features such as bulk-data transfers, frame auto-repeat, automatic retries on the same channel or bus switching on alternate channel, programmable gap times etc
RT mode supports all advanced features including single buffering, double buffering, sub-address circular buffering, programmable command illegalisation and Busy etc.
MT modes allows all standard features including word monitoring, selective message monitoring etc
Simultaneous RT / monitor mode is also supported as it is required some times for backup BC terminals.
Hard-warable and Software Programmable RT Addressing
The RT address of each channel on the CCPMC-1553B-3Node may be set by Library functions. RT address is also settable through Hardware settings as per notice-2 features. In this mode the software addressing is disabled.
BC Trigger / RT Status
An external trigger line is provided for each channel to allow hardware control of the BC. Messages may be pre-programmed, and then the BC can start from the point the trigger signal is activated.
In RT mode this line becomes a sub-system status line, used to indicate a failure within the sub-system.

Test Equipments Parametric Monitoring Software for APOORVA PCI-1553B & BISA-PCI-1553B cards
Introduction
The PARMON (Parametric Monitor) Software is user friendly and can be easily operated by a person having working experience with MIL-STD-1553B systems. The following are the main functions supported by PARMON.
BC Scheduler Software: Schedules the messages for each minor frame.
Monitor Software: Monitors the activities on the bus.
RT Simulation Software: Simulates all the Remote Terminals (31RTs) simultaneously.
RT Validation Software : Provides the standard RT validation test routines
SOFTWARE - GENERAL
TThe PARMON software is windows based menu driven type. The main menu looks like:
| BC/RT/MT | RS-422 | DATABASE | RUN | QUIT |
Optional: AA database of Engineering parameters can be generated from ICD supplied in CD/DVD in ORACLE database and to be loaded accordingly. The database will be loaded on default whenever the Software is executed. Provision to update the database whenever there is a change in ICD exists in the Software. The provision to update the database is on selection of DATABASE menu as shown above.
Bus Controller can initiate transaction just like Mission Computer of Avionics System. It generates messages according to a definable scheduler. The scheduler is compatible to Mission Computer scheduler. The BC Scheduler has the following features.
Provision to create 600 messages with Message names as given in Avionics Interface Control Document, of following types which can be added freely in any minor frame.
BC to RT Transfers
RT to BC Transfers
RT to RT Transfers
Broadcast Type Transfers
Mode Codes as per Notice-II of MIL-STD-1553B standard.
Maximum length of Message name is equal to 20 characters.
Provision to store data to be transmitted in that particular message in hexadecimal and engineering values.
Provision to change the data while BC is scheduling the messages.
Provision for sending the data stored in a table for that particular message. This will cater to create dynamic changing of data from BC side for that message. It is possible To read a file and store the data in selected message.This will help to reduce the work involved in keying in the data. This will also assist in scheduling the data captured though Bus Monitor.
Create Scheduler, which consists of major cycles of duration 160 mSec.
Each major cycle consists of 8 minor cycles of duration 20 mSec.
Provision to change the duration of major cycle- and minor cycle in steps of 1 mSec.
Provision to change the No. of minor cycles per major cycle from 1 to 32.
Provision to load a file on default whenever the software is executed.
Provision to add messages in minor frame with programmable inter message gap in steps of 1μsec.
Provision to save scheduler in any drive/directory and load it from any drive / directory.
Provision to RUN the BC for definite number of major cycles, definite amount of time (Ex: 5 minutes etc.) or indefinitely.
Provision to display the No. of major cycles and minor cycles run / amount of time elapsed while running as BC.
Remote Terminal will be able to transact data with BC and any other subsystem as commanded by BC.
Capable of emulating up to 31 Remote Terminals simultaneously at a time.
Valid value of Remote Terminal address is from 1 to 30.
RT selection is by entering RT address. Also RT can be selected using names it self.
Capable of looping back the data (Loop Test). Time broadcast data is sent by BC to all RTs to receive on Sub address 29. The second word of that data is to be sent back in Loop back and MSW message (Transmit sub address 4).
Provision to set bits in status word is provided (Ex: Busy Bit, Service request bit). The setting of bits for 1 major cycle or continuously or for few major cycles is provided.
The data sent by an RT is stored in tables. The data to be sent is keyed in engineering values. For each sub address it is possible to store data, which will be transmitted by RT for every major cycle on BC command, which will assist in creating dynamic data transmission. It is also be possible to read a file and store the data in selected sub address and particular word. This will help to reduce the work involved in keying in the data. This will also assist to input the data captured though Bus Monitor.
When an RT is configured and running the RT number and name will be displayed on run screen.
RT VALIDATION SOFTWARE
Provides RT Validation Tests that are feasible with S/W programming.
The following tests can be done with PARMON:
Valid address test.
Invalid address test.
Word count test.
Sub-address test.
Dual redundant operation.
Mode command tests: Synchronize without data word, Transmit status, Transmit last command, Dual redundant Transmitter Shutdown & override.
Status word tests: Service request, Broadcast, Subsystem flag, Busy flag.
Broadcast messages tests:
BC-RT broadcast command Broadcast synchronize without data word
Broadcast synchronize with data word
Broadcast transmitter shutdown and override
RT-RT broadcast command
RT-RT transfer tests:.
RT-RT transmit
RT-RT receive
With the PARMON, the following Errors can be injected to verify the LRUs and other systems functioning:
Manchester errors
Bit length errors
Word count errors
Bi-phase errors
Sync errors
Gap time introduction etc.

When the check box is selected the PASIT will start storing the data. When the check box is deselected it will stop recording. A dialogue with provision to enter file name is provided. If a file already exists with the filename entered warning message will be posted on the screen.
The provision to display graph of any parameter selected for online monitoring versus Major cycle No. is available. It is also be possible to display 4 graphs together for 4 Engineering parameters during online monitoring.
The captured messages will be displayed with message names and engineering values.
It will be possible to print the captured data to printer/file. Provision to print selected range of messages / range of pages also provided.
It will be possible to filter the captured data in following methods.
It will be possible to filter the captured data in following methods
