62 FEX300, FEX500 OI/FEX300/FEX500-EN
6.4.2 Bus address settings
The bus address is automatically allocated at the FF via LAS (link active scheduler). For
address detection, a unique number is used (DEVICE_ID). This number is a combination of
manufacturer ID, device ID and device serial number.
The behavior when switching on the unit corresponds to Draft DIN IEC / 65C / 155 / CDV of
June 1996.
The mean current consumption of the device is 10 mA.
The voltage on the bus line must lie in the range of 9 … 32 V DC.
Important (Notice)
The upper limit of the current is electronically limited. In the event of an error, the FDE (= Fault
Disconnection Electronic) function integrated in the device ensures that the current
consumption cannot exceed a maximum of 13 mA.
