6.5 Encoder object architecture
The Figure shows the general architecture and the mapping of the
Encoder Object (EO) architectural elements to Communication
Objects of the Peripheral Device for PROFINET IO. General with
PROFINET IO the EO is mapped exactly to one Module/Slot. Slot 0
is exclusively reserved for Device representative purpose and
therefore shall not used for any Encoder module. Valid Slot numbers
for Encoder Objects are from 1 to 0x7FFF. Every EO contains at
least the mandatory Module Access Point (MAP) which is mapped to
a dedicated EO representative Submodule. This MAP Submodule
contains at least the mandatory Parameter Access Point (PAP) which
is mapped to a dedicated Record Data Object. Via the EO
representative Submodule (MAP) and the specified Record Data
Object the access to the EO parameter manager is possible. The EO
parameter manager has access to the EO local Parameter Data
Base. In addition to the mandatory MAP submodule, the EO may
contain additional submodules which may be used to:

represent communication end points for IO Data (cyclic data
channel) and also to structure the IO Data in data blocks
(telegrams, signals).

represent physical or logical Subobjects of the EO.
