The mailbox commands can also be activated with PROFIBUS-DP V1. Even the pro-
cess data exchange is possible via the mailbox. In that way the configuration software
"AS-i Control Tools" can run the whole communication via DP V1.
7.2
DP V1
To exchange data between the PROFIBUS master and the AS-i/PROFIBUS gateway
via PROFIBUS-DP V1 only one data block is used - slot 1, index 16. Within this data
block a mailbox is installed like the one used in the DP telegram.
The DP V1-mailboxes are processed every time they are called. Therefore it is pos-
sible, to execute the same command several times without changing "command" or
"circuit".

7.3.1
Construction
If an AS-i slave is addressed in a command or in a response, the address is structured
as shown below:
Command byte and T-bit are always part of the response. The T-bit is necessary to
operate the mailbox via a MSC1 connection (PROFIBUS-DP V0). In that way the
same mailbox command can be used two times directly one command after the other
with different parameters.
The execution of a mailbox command is declined, if the number of the transfered pa-
rameters is too small, that means the mailbox in the cyclic channel is too small or the
DP V1-telegram is too short.
The mailbox commands are valid as well for PROFIBUS DP V0 as PROFIBUS DP
V1.
Circuit = 0 If AS-i gateway with one AS-i master or the master 1 of an AS-i gateway
with 2 masters is choosen.
