byte type range description
status byte Word 0…255 bit 0 = load output
bit 1 = short circuit
bit 2 = overload
bit 3 = low voltage
bit 4 = excess temperature
bit 5 = excess temperature
bit 6 = limit value current
bit 7 = event
»True« means the status is active.
byte type range description
Control 0 byte 0…255 bit 0 = load output ON/OFF
bit 1 = reset load output (only responds to rising edge)
bit 2 = reserve
bit 3 = reserve
bit 4 = reserve
bit 5 = reserve
bit 6 = reserve
bit 7 = reserve
»True« means the status is active.
8.2.1 Status circuit protector
Design of the input byte per channel is as follows (status circuit protector):
fig. 17: Status channel
8.2.2 Control circuit protector
Design of the output byte per circuit protector slot is as follows (control circuit protector):

8.3 Submodule measuring values
Depending on the number of 18plus-AM03 connection modules
used (one 18plus-AM03 connection module equals two channels)
four bytes input data with measuring values of load current and
load voltage of the corresponding circuit protector are made available per channel. The sub-module does not have output
data.
The sequence of the measuring values is load current (2 bytes),
followed by load voltage (2 bytes)
Example:
8 18plus-AM03 connection modules equal 16 channels. This results in 16*4, i.e. 64 bytes for the data exchange.
Addressing is effected according to the 18plus-AM03 sequence.
18plus-AM03 1, channel 1.1 byte address [0..1] load current, byte address [2..3] load voltage
18plus-AM03 1, channel 1.2 byte address [4..5] load current, byte address [6..7] load voltage
18plus-AM03 1, channel 2.1 byte address [8..9] load current, byte address [10..11] load voltage
