Siemens 6ES7288-6EC01-0AA0: SIMATIC S7-200 SMART Signal Board SB EC01 (Ethernet Expansion)

The Siemens 6ES7288-6EC01-0AA0 (Signal Board SB EC01) is an Ethernet expansion module designed exclusively for the SIMATIC S7-200 SMART PLC series. Installed directly into the front signal board slot of an S7-200 SMART CPU, it adds an additional 10/100 Mbps RJ45 Ethernet port without increasing the CPU's physical footprint inside the electrical panel.

This signal board allows industrial automation systems to expand networking flexibility—enabling simultaneous connection to HMI panels, programming workstations, SCADA systems, or secondary PLCs over separate IP subnets.

Key Features and Industrial Benefits

Zero Cabinet Footprint Expansion

The SB EC01 signal board plugs straight into the front expansion slot of the S7-200 SMART CPU. This provides an extra communication port without occupying DIN rail space or requiring external expansion racks.

Dual-Net Isolation & Flexible Networking

Equipping your PLC with an additional Ethernet port allows separate network segmentation. You can dedicate one port to local machine devices (HMIs, drives) and the second port to plant-wide networks (SCADA, MES, or remote monitoring).

Seamless STEP 7-Micro/WIN SMART Integration

Easily configured within the STEP 7-Micro/WIN SMART programming environment without complex setup steps, streamlining commissioning time.

High-Speed Reliable Communication

Supports fast 10/100 Mbps data transfer speeds for reliable real-time communication between industrial hardware.

Applications

• S7-200 SMART PLC network expansion in manufacturing automation

• Network isolation between machine-level HMIs and factory-wide SCADA systems

• Connecting additional Modbus TCP or PROFINET field devices

• OEM packaging machinery, HVAC control panels, and automated assembly stations
