NFC can replace DIP switches, service UARTs and other electromechanical elements. A passive NFC interface IC in the device allows an NFC phone to read and write data to it
without external power.
- Cost savings: An NFC connected tag IC costs less than a typical DIP- or rotary switch
- More parameters: Up to 2 kB of parameters can be saved, without increasing the front panel space
- Zero-power operation: The device can be unpowered during programming and read-out as it is powered via the NFC field
- Fully sealed devices: NFC penetrates plastic, glass, and wood and allows devices with high IP protection classes
- Zero-power programming of device parameters: Settings are transferred to the device with a simple tap. Works with Android NFC phones.
- Diagnosis and maintenance: Instead of connecting to the device via a service UART, status information or error logs are read out by the phone with a
simple tap – even if the device is unpowered. Works with Android NFC phones and iPhones (IOS11 and up).
- Firmware update: Even smaller firmware images can be transferred to the unpowered device at up to 40 kbps via NFC. Works with Android NFC phones.
