Arrangement of the AS-i slaves in the process image (Sort)
In TIA Portal V14 SP1 and higher, the arrangement of the AS-i slaves in the process image
can be sorted automatically. 3 options are offered in the Properties of the AS-i master under
"I/O Addresses > Arrangement":
● Sort - CLASSIC:
The digital inputs/outputs of the slaves are sorted into the process image as described in
Table 7-1 "Bit assignment per digital slave (CLASSIC sorting)", starting from the set start
address of module CM AS-i master ST. CLASSIC sorting is the same as that described in
SectionI/O addresses without configuration of the AS-i slaves in STEP 7 (Page 50).
After the digital inputs/outputs, the analog inputs/outputs are sorted into the process
image. The status information (EFD, CM, CFGOK, DIAG) is displayed if the option
"Process image for status information" (FW V1.1 and higher) is activated, see Table 7-3
"Overview of status information".
● Sort - LINEAR:
The digital inputs/outputs of the slaves are sorted into the process image as described in
Table 7-2 "Bit assignment per digital slave (LINEAR sorting)": The digital inputs/outputs of
the slaves with a standard address or A address are mapped in bits 0 ... 3, whereas the
digital inputs/outputs of the slaves with a B address are mapped in bits 4 ... 7.
After the digital inputs/outputs, the analog inputs/outputs are sorted into the process
image. The status information (EFD, CM, CFGOK, DIAG) is displayed if the option
"Process image for status information" (FW V1.1 and higher) is activated, see Table 7-3
"Overview of status information".
● Packing:
Address usage for the inputs/outputs of the slaves is optimized, i.e. all gaps are
eliminated and the length of the I/O area is adapted. You can see the selected I/O
addresses directly in the address overview of the I/O addresses in the configuration of the
CM AS-i master ST.
