In the responses' data field, you can read the bit mask (0x41) that corresponds to the read discretes' status
after shifting with the 'Reference number' field value (0x00, 0x00).

Table 4-10: Response's Data Block Broken into Bits
In this example, the frequency converter is in the 'ready' mode because the first 0 bit is set. The motor does
not run because the 6 bit is set.

Holding Registers (400001 - 410633)
You can both read and write data from the MODBUS holding registers. The Ethernet board's MODBUS/TCP
implementation uses the following address map.

400001 – 402000 and 402200 – 410000, Application ID
Application ID's are parameters that depend on the frequency converter's application. These parameters can
be read and written by pointing the corresponding memory range directly or by using a so-called ID map
(more information below). It is easiest to use a straight address if you want to read a single parameter value or
parameters with consecutive ID numbers.
