Example:
Byte [0] = 03
hex
corresponds to a set nominal current of 3 A on channel 1. In the case of write
access, whole-number nominal currents from 1 to 4 A or 1 to 10 A are accepted, depending
on the device variant.
The individual nominal currents of channel 1-4 are read- and writable under Subindex 1-4.
Error memory
The device offers the possibility of retrieving an error history via Index 3332
dec
. The last 15
errors are encoded in 15 bytes. The latest errors are located in Byte [0] and the oldest in
Byte [14]. If a new error is recorded, the oldest error is deleted in parallel (FIFO principle).
The values in FIFO have the following meaning:
Nominal current channel 4
Byte 3 Bit 7 Bit 6 Bit 5 Bit 4 Bit 3 Bit 2 Bit 1 Bit 0
0 0 0 0 1/0 1/0 1/0 1/0
