C.10 MEMOBUS/Modbus Data Table Units are determined by parameter H5-13. The contents of a communication error are saved until the fault is reset. 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 History Contents The table below shows the fault codes that can be read out by MEMOBUS/Modbus commands from the U2- monitor parameters.
