F 8628X (0650)
429
7.3.3 Example 3
In this example, the WORD variables in export area 0 (on the F 865x) start with BUSCOM ad-
dress 1 and are mapped to the memory area EV (on the F 8628X) beginning with identity num-
ber 1. The identity numbers of the WORD variables in memory area EV are in ascending order
up to the last WORD variable (0110) from export area 0.
The unused BUSCOM address 0 is assigned a dummy variable and mapped to identity num-
ber 0 within memory area EV.
In this example, the
WORD variables in export area 1 (on the F 865x) start with BUSCOM ad-
dress 4100 and are mapped to the memory area EV (on the F 8628X) beginning with identity
number 115. The identity numbers of the WORD variables in memory area EV are in ascend-
ing order up to the last WORD variable (4200) from export area 1.
The unused BUSCOM addresses 4096 to 4099 are assigned dummy variables and mapped
to identity numbers 111 to 114 within memory area EV.
In this example, the
BOOL variables in export area 0 (on the F 865x) start with BUSCOM ad-
dress 0 and are mapped to the memory area EV (on the F 8628X) beginning with identity num-
ber 216 which follows the identity number 215 of the last WORD variable from export area 0.
The identity numbers of the BOOL variables in memory area EV are in ascending order up to
the last BOOL variable (0100) 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 the memory area EV (on the F 8628X) beginning with identity
number 317 which follows the identity number 316 of the last BOOL variable from export area
0.
The identity numbers of the BOOL variables in the memory area EV are ascending up to the
last BOOL variable 4196 from the export area 1.

Note If BUSCOM variables do not start at the beginning of an area, this area
is padded with dummy variables on the central module and also
mapped on the communication module.
