RFID tag with effective range
The RFID tag is a storage device for a configured ID. The ID of the RFID tag is required for a
HMI device to log onto a machine. The RFID transmission and reception range of the HMI
device is brought into the effective range of the RFID tag in order to log on.
A signal lamp indicates whether an HMI device is logged onto a machine.
