1. This register location represents the sequential registers and their numbers within the device itself; as illustrated in Figure 5.1 in Chapter 5, the data
register numbers in the Modbus Master and the DTU3005 unit itself will vary from these register numbers.
2. Status information for each parameter is transmitted in two bits. The status bit indicates status (true = 1, false = 0) for the parameter and the valid bit indi-
cates that the device has sucessfully updated the value in the status bit (true = 1, false = 0).
