Telegram description

Particular features

In a Sinaut 4-FW-telegram a maximum of 323 bits with the same level can occur (logical 'one'). For technical reasons up to 3 seconds may pass before SIMO puts out on screen the received data of single telegrams. No information is lost.

Simulation

You can transmit messages (during rest operation) in the background without any interruption when you enter the following under SIMO-"SendMessage":

"RTU < buffernumber >"                 or                            "RTI < Puffernummer >"

SIMO interrupts the transmission in the background if a message or sequence is transmitted by hand. You can switch off the transmission in the background by entering

"RTU"                                              or                            "RTI"

without any parameter

Transmission errors

*F:Blocklength :   A message exceeds the maximum permissible length of 337 bits or doesn't contain at least one half-word.
*F:Parity : The parity bit is incorrect.
*F:Hammingcode : The check code is incorrect.
*F:SYNC :   The synchro word is not correct
*F:TelegramFormat : One of the compulsory signs SA, VS, TR or SE indicates the wrong level.
