7.15.10 Hardware monitoring
The hardware monitoring feature provides some hardware specific parameters such as power supply, board
temperature and operating time.
7.15.10.1 Object 0x2803: CPU supply voltage
This parameter contains the value of the CPU supply voltage (in mV). A fault is generated if the parameter is
outside its nominal range.
Nominal range: 3.1 V ≤ CpuSupplyVoltage ≤ 3.5 V
Value description
7.15.10.2 Object 0x2804: Power supply voltage
This parameter holds the value of the power supply voltage (in mV). A fault is generated if the parameter is
outside its nominal range.
Nominal range: 17 V ≤ PowerSupplyVoltage ≤ 32.5 V
Fault description

CpuSupplyVoltage < 3.1 V 0x07 Internal supply voltage too low.
CpuSupplyVoltage > 3.5 V 0x08 Internal supply voltage too high.
Table 97: Fault codes
The power supply voltage should be in the range of 18…32 V to ensure proper operation.
