LIAN / SIMO - Operation mode
In LIAN the number of address words can be set ( 1 or 2 ). This affects the data interpretation. The transmission / reception level in LIAN must be parameterized correctly.
Background simulation ( empty telegrams )
In order to transmit in SIMO empty messages in the background the command "RTI < buffer number >" is to be used. Then SIMO transmits telegrams given in the buffer <buffer number> without interruption. The background simulation is only interrupted by transmitting a telegram ( e.g. command : SS , SF , SZ ). You can switch off the background simulation by entering "RTI" without any further parameter.
In program FIPP you can set the pre-filter of the regarding channel to "ADRE H: # 000" in order to filter out empty telegrams during receipt. You will not receive further empty telegrams.
|*F:Block length :||Message doesn't consist of 99 bits.|
The measured character length is beyond the tolerance set in LIAN and cannot be allocated to a number of bits. The sensitivity is adjustable via the parameter tolerance limit.
|*F:Spike :||The length of a received character is smaller than 20% of the length of a bit.|
|*F:Parity :||The parity bit is wrong.|
|*F:SYNC :||The synchro word ( 0 111111111 1 ) was not received correctly.|
|*F:BlockCheckCode :||Longitudinal parity ( LC ) is wrong.|
|*F:Start / Stop bit :||Partition step was not received correctly.|
