u Broadcast Messages
Data can be written from the master to all slave devices at the same time.
The slave address in a broadcast command message must be set to 00H. All slaves will receive the message, but will not
respond.
u Fault Trace Contents
The table below shows the fault codes that can be read out by MEMOBUS/Modbus commands from the U2- and
U3- monitor parameters.
