The recording of an existing coupling unit is checked on occurring offenses or differences to a "trouble-free" data transmission (limited procedure monitoring). Please make sure that reception and transmission lines are plugged.
The protocol file of the coupling unit contains beside practical data all protocol- dependent control signs.
Detailed information for transmission
with ENQ : Enquirly
ACK0 / ACK1 : Acknowledge ( positive Ackn )
EOT : End of Transmission
|The faultless receipt of blocks is signed alternately with mit ACK0 and ACK1 to the recognition of sequence errors.|
with STX : Start of Text
ETX : End of Text
TPAD : Trailing Pad ( wird auch gesetzt nach ENQ , EOT , ACKI ,NAK )
The first character of a data block is a qualifier.
At most 7 formats, which are checked as regards content, are transmitted with the transmission routine.
Because of the restricted monitoring procedure it is only tried to recognize a format with the monitoring operation, because Signatrans ZM 400 system- and process commands are not registered with the current implementation.
A format consists of 10 signs with the following description
data word 0
data word 1
data word 2
data word 3
data word 4
data word 5
LIAN / SIMO - Operation mode
Monitoring times can be checked indirectly by a suitable timeout-parameterization. Counter repetitions are not implemented..
The filter aims primarily at the tranmission of a format (after the identyfier ). Formatchainings are not supported.
|*F:Blocklength :||Data transmission block is too long.|
|*F:ACKNumber :||Receipt of an invalid ACK-number.|
|*F:BlockCheckCode :||The telegramm check sum in the BCC-Byte is faulty.|
The receive routine searches for ENQ, ACKi, NAK, STX, EOT, CTRL_I ( Terminalmode ).when setting up. Each other sign is marked with an asterisk '*' in SIMO and as synchronization error in the protocol-file.
|*F:EndofText :||Invalid ETX-character at that position.|
|*F:TelegramFormat :||Format error with the transmissen routine or invalid value within a format.|
|*F:TrailingPadChar :||An expected TPAD-sign was not received.|
|*F:SOZ :||Invalid special character in the data block.|
|*F:Overflow :||Error message by UART|
|*F:Parity :||Error message by UART|
|*F:Start / StopBit :||Error message by UART|
