Note 3: POS = Power on/off status

• 0 = Power off

• 1 = Power on

Note 4: SPS = Set point status

• 0 = Not at set point

• 1 = At set point

Note 5: TS = Temperature status

• 0 = Overtemperature

• 1 = Not at overtemperature

Note 6: INTS = Interlock status

• 0 = Interlock not satisfied

• 1 = Interlock satisfied

Scaling

Parts of the message structure are based on binary representations of analog voltages

and have analog scaling associated with them.

DeviceNet uses unsigned binary to represent zero to the full-rated output power of the

HFV generator (scaled 0 V to +10 V). Use

the corresponding digital values (assuming N is the number of bits of resolution

available at the DeviceNet interface).

Table 4-37. DeviceNet voltage ranges

AI/AO Digital Value (at the

DeviceNet interface)

The conversion is assumed to be linear across the range (a one-bit change always

corresponds to the same change in output power within the hardware capabilities of

the power supply.

Values exceeding 0FFFh are limited to 0FFFh. Thus, the maximum calculation of a 10

kW unit (at 12-bit resolution) is 0FFFh (or 4095 decimal).
