Near Field Communication - ABB CM-TCN Manual

Near Field Communication

For the CM-TCN device, NFC communication can be disabled either via the dis-
play menu on the device itself or through the app.
NFC pairing
If the device is powered the button needs to be pressed for three seconds to en-
able NFC while on the main screen. This enables NFC-pairing for 15 seconds, dur-
ing which time a connection must be established. During the 15 seconds time
frame the LED is blinking orange.
When the first communication was successful NFC stays enabled for another 5
minutes.
This ensures that NFC communication can only be established by an authorized
person, which has access to the device and pushes the button.
If the device is unpowered NFC communication is always enabled unless se-
lected otherwise.
