Features:
- N-AT identity: board silkscreen and labels define the interface role.
- Local-bus connection: system records link OS 525 with the CS 275 20 m bus.
- Software boundary: programmed-device versions belong in the replacement record.
The N-AT marking connects the board identity to its documented TELEPERM M system role.
EPROM labels and switch positions should be recorded independently from the hardware catalog number.
Installed slot and bus topology provide the final context for configuration comparison.
For Siemens 6DS1222-8BA N-AT Local-Bus Interface Module requirements, Apter Power provides technical-document review, quotations and procurement support.
