10.2.3 EtherCAT register map
There are seven different release types in the NZM digital circuit breaker
family. As a result, the devices access the registers differently, since not all
versions support all functions.
The release type -AX does not support a communication connection; register
access is therefore not possible.
10.2.3.1 Input status (discrete inputs)
The input status bits can be requested via sub index: 0 and index 2001 (Hex).
The input status answer is a 4 bytes data type. The first 16 bits (1001 - 1016)
indicate the current status, while the last 16 bits (1017 - 1032) indicate
whether the corresponding status is valid or supported by the release unit.
