10.1.3 Description of the fields Extended message set # 2
The extended message set 2 permits a memory area exchange between the master and the
drive with both communication and real-time mode. The data exchange is synchronous: the
data, transmitted from the master to the device, are stored in a temporary buffer; when the
master sends the synchronous message to all the drives, each device copies the temporary
buffer onto the writing block area and sends back the reading block area.
