Figure 15 – NFC HEADER area structure
The NFC HEADER contains the following fields:
START
 This field identifies the start of the NFC header and is always set to 0xE0.
LENGTH
 This field identifies the length of the NFC header.
 This field is set to 0x0A since the header structure is 10 bytes long.
VERSION
 This field identifies the major revision of the NFC specification.
MAN ID
 The 16-bit Manufacturer ID is assigned by the EnOcean Alliance.
The field identifies the manufacturer of the device so that manufacturer-specific layout
implementations can be determined.
 For EnOcean GmbH products this field is set to 0x000B.
NFC Struct ID
 The 24-bit NFC Struct ID field identifies an individual device from the range of devices
manufactured by the manufacturer specified in the Manufacturer ID field.
 For PTM 215, the NFC Struct ID is set to 0x000001.
REVISION
 The REVISION field identifies the exact revision of the NFC layout.
 The REVISION will be incremented whenever a change to the NFC layout is made.
Changes are possible only when 100% backwards compatible to all previous revisions.
If changes are not compatible a new NFC Struct ID must be defined.
