Telegram structure :
|Synchronization signs :||2 x FA hex with even parity ( LSB - first ).|
|Data :||8 bit with uneven parity ( LSB - first ).|
|Each telegram cycle is started with 2 synchro bytes , followed by data bytes which can be parameterized.|
The receive module first searches for the two synchro bytes when setting up. In SIMO correctly received signs are displayed by a dot "." (and entered into the protocol file). In SIMO / TRAP data bytes are analysed only generally because the assignment of information signs may be parameterized individually ( via a table of cycle descriptions ). For this reason filter and trigger setting is not possible , too.
The simulation mode is implemented for transmission cyclically without break. When entering "rtu" into transmission window in SIMO the current send buffer will be transmitted cyclically. If a new telegram is selected and sent with "ss" it is repeated cyclically until a new telegram is to be transmitted. Entering "rtu"again the simulation mode is ended.
Only each first telegram is entered into archive. Transmission on the other channels is only possible if they are parameterized with PCM. The commands "ss" , "sm" and "sz" are structured analogously , i.e. a new cyclic telegram is transmitted ; it is not displayed in the transmission list ( => "ps" ) and cannot be deleted with"kill" ( only via "rtu" such a job can be ended ). Sequences are only transmitted without establishing a new background job.
The measured time between two slopes cannot be assigned definitely to a certain number of bits. The sensitivity of SIMO is adjustable via the parameter tolerance limit
