Protocol : ABB - RP570 / RP571

Telegram structure :
RP 570/571 uses the IEC 870-5-1 FT 1.2 telegram format with variable and fixed length as well as the single character E5H.
|The number of data bytes in the single message is fixed
or variable. Therefore automatically the exact or minimal length is set.
If a bigger as the minimal length is set with previous selection of the same ( var. ) message this value is unchanged.
A manipulation requires an exact knowledge of the relevant message format. This is applied also to the M / D-Bit with some commands. Therefore the information are supplemented by "( ! )"
The FCODE of each message is clearly determinated and should not be changed.
|There is no check of the maximal length.
If no name could be assigned to the telegram , but the remaining checks ( check sum etc. ) had proceeded positively , the symbol "???" is set instead of the name.
There is no more analysis of practical data ( as of data byte 3 ) of the respective ( var. ) telegram types.
|*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 parametrized in the program LIAN.|
|*F:SYNC :||The receive routine initially searches for the start-byte ( 68H or 10H ). Every other character is given an asterisk "*" in SIMO and a synchronization error is noted against it in the protocol-file.|
|*F:Overflow :||Error message by UART.|
|*F:Parity :||Error message by UART.|
|*F:Start/Stop :||Error message by UART.|
