Particular features

At the beginning of the telegram , SIMO searches for the synchronisation characters ( 1 , 1.5*0 , 1 , 0 ).All other bit patterns are entered as synchronization errors in the protocol.

Telegram structure :

MSB_FIRST is to be sent

Simulation :

Via the command "rtu <station address>" or "rti <station address>" in SIMO in the window "SendTelegram" you can activate the simulation. Is no parameter declared , the settings of the program LIAN are taken on. All telegrams to be sent are attached with this station address.

Bit shifter :

In SIMO you can activate a bit shifter via the command "bs". It enables you to set a bit or the BMK conveniently into the information block of the relevant message. When exceeding the information area the address block is automatically increased or reduced. The bit shifter works only with single bits , double bits and pulse commands.

In the window "bit shifter" you can use the following command :
[ 1-9 ] define interval n ( not in case of pulse commands )
[ arrow-right ] n bit / double bit to the right ( or increases BMK )
[ arrow-left ] n bit / double bit to the left ( or increases BMK )
[ arrow-up ] increase common block by 1
[ arrow-down ] reduce common block by 1
[ S ] send telegram
[ ESC ] quit entry mask
It should be taken into account that the bit shifter changes the address block and the information block; previous settings are lost.

Transmission errors

*F:TelFormat :   The format byte with the telegram length includes an invalid value.
*F:Timetolerance : The measured character length includes an invalid value.
*F:Parity : Parity error.
*F:Hamming code : The check code was incorrect.
*F:Endcharacter : The last character in the telegram is not equal to 0.
