7.3.2 Example 2
In this example the BOOL variables in the export area 0 (on the F865x) start with the BUSCOM
address 0 and mapped to the memory area EV (on the F 8628X) with the identity number 0.
The identity numbers of the BOOL variables in memory area EV are in ascending order up to
the last BOOL variable (identity number 100) from export area 0.
In this example, the
BOOL variables in export area 1 (on the F 865x) start with BUSCOM ad-
dress 4096 and are mapped to memory area EV (on the F 8628X) beginning with identity num-
ber 101, which follows the last identity number of the BOOL variables (i.e. 100).
The identity numbers of the BOOL variables in memory area EV are in ascending order up to
the last BOOL variable 4196 from export area 1.
