A command of the command interface will be edited if the toggle bit T has
changed. This way the same command can be used repeatedly.
The commands of the command interface can also be activated with PROFIBUS
DP V1. Even the process data exchange is possible via the command interface.
This way the Windows configuration software "AS-i Control Tools" can run the
whole communication via DP V1.

DP V1
To exchange data between the PROFIBUS master and the AS-i/PROFIBUS gate-
way via PROFIBUS DP V1 only one data block is used - slot 1, index 16. Within
this data block a command interface is installed like the one used in the DP tele-
gram.
The DP V1-command interfaces are edited every time they are sent. Therefore it
is possible to execute the same command several times without changing "com-
mand" or "circuit" and setting a toggle bit.
