What this cable does in the S7-300 rack
The Siemens 6ES7368-3CB00-0AA0 is a 10-meter Cable 368 that connects the IM 360 interface module in the main rack to the IM 361 in an expansion rack, extending the S7-300 I/O bus across cabinets. It comes pre-terminated with the connectors needed for both ends — no field wiring or crimping required.
