byte type range description
reason for
trip 4 byte 0…255 0 = no trip
1 = short circuit
2 = overload
3 = device temperature too high
4 = internal device failure
min. load
voltage 5 HighByte
6 LowByte Int Contains the highest measured voltage of the channel since the last reset.
A standardised 16-bit-value with a resolution of 10 mV is made available.
Example for calculation of the measuring value:
Value (2512): 100 = 25.12 Volt
max. load
voltage 7 HighByte
8 LowByte Int Contains the highest measured voltage of the channel since the last reset.
A standardised 16-bit-value with a resolution of 10 mV is made available.
Example for calculation of the measuring value:
Value (2512): 100 = 25.12 Volt
medium
value load
voltage 9 HighByte
10 LowByte Int Contains the mean voltage value of the channel since the last reset.
A standardised 16-bit-value with a resolution of 10 mV is made available.
Example for calculation of the measuring value:
Value (2512): 100 = 25.12 Volt
min.
load current 11 HighByte
12 LowByte Int Contains the lowest measured current of the channel since the last reset.
A standardised 16-bit-value with a resolution of 10 mA is made available.
Example for calculation of the measuring value:
Value (150): 100 = 1.50 Ampere
max.
load current 13 HighByte
14 LowByte Int Contains the highest measured current of the channel since the last reset.
A standardised 16-bit-value with a resolution of 10 mA is made available.
Example for calculation of the measuring value:
Value (150): 100 = 1.50 Ampere

current 15 HighByte
16 LowByte Int Contains the mean current value of the channel since the last reset.
A standardised 16-bit-value with a resolution of 10 mA is made available.
Example for calculation of the measuring value:
Value (150): 100 = 1.50 Ampere

age 17 HighByte
18 LowByte Int shows the operating voltage of the channel
A standardised 16-bit-value with a resolution of 10 mV is made available.
Example for calculation of the measuring value:
Value (2512): 100 = 25.12 Volt
Temperature 19 HighByte
20 LowByte Int The device temperature is shown directly.
Example: 25 corresponds to 25 °C
diagnostic
information
of channel 21 byte 0…255 0 = OK
1 = available device type does not match the configured type
2 = no device detected
144 = device parameters not plausible
145 = no bar chart
146 = slide switch is in OFF position
147 = detected undervoltage
148 = detected excess temperature
149 = reset command required
150 = command was processed correctly
151 = parameterisation required
152 = Internal failure detected
153 = unknown command
154 = set length error
155 = rated current available, check sum error
156 = current rating selector switch was actuated
