PTM 535BZ – BLUETOOTH AND ZIGBEE GREEN POWER PUSHBUTTON TRANSMITTER

5 NFC configuration

PTM 535BZ provides an NFC interface according to the ISO15693 standard for identifying and

configuring device parameters. The NFC interface provides a textual description of key device

parameters in NFC Data Exchange Format (NDEF), a register-based description of the current

device configuration and a configuration update service with two permission levels.

5.1 Architecture

The NFC configuration architecture of PTM 535BZ is designed to provide configurable permis-

sions so that a user with higher level access rights (for instance an OEM or System Integrator)

can restrict the set of available configuration options for a user with lower level access rights

(for instance an Installer) to avoid unintended reconfiguration of certain device parameters.

PTM 535BZ supports requests to change the value of configuration register(s) as well as

requests for transmission of a commissioning telegram, for factory reset and for transmission

of a ZGP decommissioning telegram (only when transmitting ZGP data telegrams).

If an update of configuration register(s) is requested, then the CONFIGURATION_SELECTION

PTM 535BZ supports two users (USER1 and USER2) with different access rights (defined by

USER1_CONFIGURATION_OPTIONS and USER2_CONFIGURATION_OPTIONS). Both users

authenticate themselves using their individual PIN codes (USER1_PIN and USER2_PIN).

Figure 35 below shows the high-level NFC configuration architecture.
