A. Parameter Data Initialization (Explicit Data)
A.1 General
The portion of the input and output data that is declared as parameter data cannot be accessed from the 
network unless it has been properly initialized.
The purpose of this procedure is to specify which data blocks in the input and output data areas to as-

Output Mapping Object.
To achieve this, it is required to set up two mailbox messages in the Mailbox Editor of the Anybus Con-
figuration Manager. For more information about the Mailbox Editor, see “Mailbox Editor” on page 
118.

This window, a.k.a. the Mail-
box Editor, will be used in the 
examples later in this chapter.
