10 Industrial Ethernet Communication Adapter Modules (ECAM)
10.2 EtherCAT
110 PXR Electronic trip unit 01/21 MN012005EN www.eaton.com
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.
