4.3.7 Querying Current Bus Parameters of the Master

Uses of the Bus Parameter Query

In the process image of the CP 5613/CP 5614, there is a memory area from which

you can read out the current bus parameters, for example, to display them in your

user program.

Example

"p" is a pointer to the process image that your user program obtained with the

"DP_get_pointer" call. To display this information in a simple application, you would

write a program similar to that below:

printf("Baudrate -> %d",

p->info_watch. aspc2_buspara.baud_rate);

The parameters are bytes, words or double words. Refer to the header file for the

formats, structure DPR_ASPC2_BUSPARA_T.
