11.8 Programming
SmartWire-DT module IP20 01/20 MN05006001Z-EN www.eaton.com 245
The following applies to devices belonging to device version 04 or higher:
Program the following logic for every switching operation:
▶ After a switching command, check whether it has been properly carried
out using the appropriate input auxiliary contacts.
▶ If two seconds have passed and the switching command still has not
been carried out successfully, cancel the switching command.
To do this, enter the original state as a switching command.
11.8.2 Decoding CB type and CB identification
A ready-to-use function block is provided since decoding is a complex opera-
tion on account of the range of different NZM types. A special description,
“Decoding CB types and CB identification,” is also provided.
Both can be downloaded from the following internet page:
