Querying the 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.
Note
Writing these values is not permitted and does not change the bus parameters
actually used.
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",
The parameters are bytes, words or double words. Refer to the header file for the
formats, structure DPR_ASPC2_BUSPARA_T.
