ENCODER OBJECT ARCHITECTURE

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 PROF-
INET 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 be
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 param-
eter manager has access to the EO local Parameter Data Base. In addition to the manda-
tory 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 struc-
ture the IO Data in data blocks (telegrams, signals).
represent physical or logical Subobjects of the EO.
