Cable identity and configuration
The Siemens 6ES7923-1BF00-0HD0 is a shielded connection cable within the Flexible Connection product family, purpose-built for the SIMATIC ET 200SP HA distributed I/O system. It terminates a 37-pole D-sub connector on one end and bare ends with wire end sleeves on the other, pre-labeled for 20 channels. The cable is 5 m long with a 0.56 mm² conductor cross-section.
Deployment context
This cable connects the ET 200SP HA interface module to field devices via the D-sub port. The 20-channel labeling on the bare ends matches the I/O mapping of the remote station, which simplifies commissioning and reduces wiring errors. The shield is continuous through the D-sub backshell; ground it at the I/O end per standard EMC practice for a distributed automation island.
