|Source Field Unit|
Field Unit address containing the RTDB to be used as data represented in this Slave unit.
32-bit data is only supported in 40,xxx RTDB registers, not 30,xxx registers. In order for the Modbus Slave Attach to work properly, the registers in the attached RTDB must be defined in a specific order. That order is:
All of the above register types are optional, but must be defined in the listed order (if present) using NOTE: The RTDB attached to the Modbus slave should include at least one register in each of the four address ranges (1, 10001, 30001, 40001), observing the rules stated in the bullets above. For instance, if the RTDB definition includes 16-bit registers after UINT32 or FLOAT registers, those 16-bit registers will not work properly when attached to the Modbus Slave.
