Within this context, an object consists of one or more sub-objects, while the
sub-object represents the module channel.
For each module, special RxPDO objects that are named based on the mod-
ule name and type are created.
Example: "XN-322-8DO-P05 RxPDO mapping"
4.1.7 TxPDO mapping object (0×1A00…0×1BFF)
The PDO mapping objects are used to define the structure of the PDOs as
per ETG 1000.6 (Application Layer Protocol Specification). The 0x1Axx
objects contain the corresponding process data mapping assignments for the
connected XN300 slice modules. The content depends on the module con-
figuration.
The numbering of the PDOs depends on the module's position in the XN300
system and is generated as follows:
• Index = 0×1A00 + (position number - 1) for input modules
