Product Overview

The 6GK7277-1AA10-0AA0 is a Siemens SCALANCE CSM 1277 unmanaged compact switch module designed to interface a SIMATIC S7-1200 controller with up to three additional Industrial Ethernet nodes. It operates at 10/100 Mbit/s, powered by an external 24 V DC supply, and provides LED diagnostics. Its role in control systems is to deliver basic Ethernet connectivity inside control cabinets or small distributed architectures. Typical use cases include expanding Ethernet ports on S7-1200 installations, compact automation cells, or small machine networks.
