PROFIBUS DP Master "Mbx Task"
Hi ,
Can I get a description "Mbx Task" displays in "PROFIBUS DP Master Protocol API rev7"
Figure 6 " Internal Structure of PROFIBUS DP Master Firmware".

Thanks for your reply AJ,
Is "Mbx Task" part system firmware (rcX or protocol stack) or user task ?

Hi Teapot,
the "Mbx Task" is part of the firmware (protocol stack) it self.
How does "user task" and "Mbx Task" interacts ?
Is there a detailed description of "Mbx Task" API ?

Hi Teapot,
your user task does not interakt with the Mailboxes.
As you can see on the picture are the MBXes in the DPM area. Your host have to work with them and not your user task.
Now I have code, wich recieve data from FSPMM task with
PROFIBUS_FSPMM_CMD_READ_REQ/CNF
and I need send this data to HOST through DPM.
How is it better to do with use "Mbx Task" ?

Hi,
sorry but I think it would be better if you get in contact with the support line from Hilscher.

Hi,
the receive mailbox is used by protocols utilizing a non-cyclic data exchange mechanism.
Another use of the mailbox system is to provide access to the firmware running on the netX chip itself.
The receive mailbox is used to transfer non-cyclic data from the network or from the protocol stack.
