Description of the parameters of array
“b_ar_modul_parameter”
The parameters are defined in the following array of 20
bytes. The array is incorporated in the declaration section of
the TCMT1zxx parameter function block.
They are assigned with default parameters so that a safe
operation is possible with all tested modems. Depending on
the type of use, it may be necessary to adjust the time
parameters.
When using GSM modems the data format must be set to
“8N1”. In order to reach the required level of data
transmission security with long frames, the frame format
must be set to “FT3“. For this the “telegrammformat” input
on the parameter function block must be set to “1“.
