Example 4:
Writing the Config Table on the connected IB IL AI4/EF
(slot 3, index 0080, subindex 0)
Here, the write specification is done in 3 fragments. The bus coupler only accepts the
request once the last fragment has been received. The response "87" indicates that
command "07" was executed. The status "0" indicates that transmission was successful.
The communication data can be reset to the initial state via "Clear".
