One Control Byte is mapped for each module. It is in the first place of the
mailbox, afterwards an empty byte and then the actual mailbox box data fol-
low.
Example:
1 byte Control, 6 bytes mailbox, 4 bytes data

With the help of this object it is possible to insert virtual modules into the
node. In this manner, for instance, a max. node extension can be projected and
a new node subsequently designed which represents a sub-quantity in relation
to the maximum configuration. The behavior of this new node with regard to
its object entries in relation to connected modules is identical to that of the
maximum configuration. As such, other applications (CANopen master,...) can
be designed once for the maximum configuration and have access to any sub-
quantity without having to change its setting.
In the same manner it is possible to provide for future extensions from the
start of the design process and making later adaptation of the mapping will be
unnecessary.
