7.2.3 Measuring values circuit protector
The measuring values contain the data of load current and load voltage of a circuit protector. The sequence
of the measuring values is load current (2 bytes), followed by load voltage (2 bytes)
Load current circuit protector
Design of the input bytes per circuit protector slot is as follows (measuring value load current):
Value range:
0 – 65535
Data length:
2 byte (unsigned integer)
Byte[0] (LOW)

The load current is made available as a standardised 16-bit-value with a solution of 10 mA.
Example: Measuring value load current = 1025
➞
real measuring value = 10.25 A

Example: Measuring value load voltage = 2456
➞
real measuring value = 24.56 V

Module control
Depending on the configuration (number of slots for circuit protectors) one byte input data with the status of
the circuit protector and one byte output data for controlling the circuit protectors are exchanged.
In the event of a power module with 16 slots, 16 bytes input data and 16 bytes output data are exchanged.
Addressing will be in accordance with the configured slots N of the circuit protectors.
Byte address [0…N-1] Status/Control.
Status circuit protector (see chapter "Module control-measuring values")
