13.2.3 Transmitting Non-Failsafe Data
The prerequisites for transmitting data are as follows:
• The location of the Send mailbox has been specified in DB1 (see section 13.2.1)
• The data to be transmitted, additional information (such as the length of the Send data ("net
data") and the destination slave number) have been forwarded to the Send mailbox.
Figure 13-6 shows which information has to be stored in what part of the Send mailbox.
Example: Example:
Send mailbox in flag area Send mailbox in data block
(starting with FY 1) (starting with DW 1)
