Telegram structure

Each message is started with 12 "ones" as synchronization signs , followed by 4 byte address and 2 byte information block. Between each byte a partition bit ( = 0 ) is set. The message ends with the check block ( PR ) (d = 4 : 1 byte , d = 6 : 2 byte ) and 3 blank bits ( LB ) ( = 0 ). LSB_FIRST is transmitted. If more than 2 information signs are to be transmitted they are coupled onto the above message. A separate check block is attached.

Particular features

In order to keep implementations low the internal telegram representation of SEB in SIMO was adapted to S8FW-PDM. That means synchronization signs , partition bits and the check blocks are not stored ; only in case of hamming failure the ( faulty ) check block is stored. Furthermore when transmitting / receiving without station number , the station number is displayed nevertheless ( by 00 ).

Simulation mode :

In SIMO you can simulate a master station or substation by the commands "rti" and "rtu".

Polling :
  
rti  [ station number ( 0 - 127 ) ] => simulate master station
rtu [ station number ( 0 - 127 ) ] => simulate substation

The station number handed over as parameter is entered into each telegram. The MSC-number is set correctly. If needed SIMO sends back telegrams automatically with the following send buffer reserved ( these buffers should not be occupied otherwise ):

Buffer 496
Buffer 497
Buffer 498
Buffer 499
MSC-acknowledge
Cause of last stop
ZF bit
Single error record

Bit shifter

In SIMO you can activate a bit shifter via the command "bs". It enables you to set a bit conveniently into the information block of the relevant telegram. When exceeding the information area the message address is automatically increased or reduced.

In the window "bit shifter" you can use the following command :
[ 1-9 ] define interval n
[ arrow-right ] n bit to the right
[ arrow-left ] n bit to the left
[ arrow-up ] increase message address by 1
[ arrow-down ] reduce message address by 1
[ E ] Toggle control "on" ( BE bit ). Control "off" is automatically set or cleared.
[ S ] send message
[ ESC ] quit entry mask

It should be taken into account that the bit shifter doesn't change the message address and the information block ; previous settings are not lost. Furthermore its application is not useful with all message types ( only indications and fleetings ). Short messages are not processed.

Filter-/Trigger-Input

Short-telegram ( StR / UeR ) :
0 = QuickCheck / Anmeldung
1 = QuickScan / NegativQuittung
2 = interrogation list 1
3 = interrogation list 2
4 = interrogation list 3
5 = interrogation list 4
6 = single query 1
7 = single query 2
8 = single query 3
9 = single query 4
Station number : 0 - 127
TGE-bit : 0 / 1

Data mode :
0 = organizational
1 = spontaneous
2 = cyclic
3 = interrogated

Telegram-Address : 0 - 1023
System-number : 0 - 7

Transmission error

*F:Blocklength : The telegram length is incorrect.
*F:Hamming code : The hamming code is incorrect.
*F:TelFormat : One partition bit or one blank bit is set for 1.
*F:TimeTolerance :
  
The measured time between two slopes cannot be clearly assigned to a number of bits. The sensitivity of SIMO can be regulated via the parameter "tolerance limit".
