Telegram structure :

SK 1703 SSI uses the standard telegram format IEC TC 57 P 5.1  FT 1.2 with fixed or variable length and the single signs.

Particular features

In the program FIPP you can filter the different message types ( 68H , 10H , E5H ,A2H ) under the item "start signal". 

Transmission errors

*F:BCCode : The telegram check sum in the BCC-Byte is incorrect.
*F:Blocklength : The stop byte  ( 16H ) is missing or set wrongly.
*F:TelFormat : The repetition of the length or the start sign in the telegram header is  faulty.
*F:TimeOut :
  
Within a telegram, there may be no pause between characters. The sensitivity  can be parameterized in the program LIAN.
*F:SYNC :
  
  
The receive routine initially searches for 68H, 10H, E5H or A2H. Every other character is given an asterisk '*' in SIMO and a synchronization error is noted against it in the protocol.
*F:Overflow : Error message by  UART .
*F:Parity : Error message by  UART .
*F:Start/Stop : Error message by  UART .
