Installation & Setup Guidance
Mount the Siemens 6AV2123-2DB03-0AX0 in vertical orientation with a 124 x 100 mm cutout. Use included clamps for panel mounting at up to 35° tilt without external ventilation. Connect a 24 V DC supply (19.2 to 28.8 V) observing polarity. Assign an IP address via PROFINET using the integrated Ethernet interface. Configure the panel using WinCC Basic V13 or higher within TIA Portal; the device supports STEP 7 Basic/Professional.
Compatibility & Integration
The Siemens 6AV2123-2DB03-0AX0 communicates natively with Siemens S7-1200/1500/200/300/400, LOGO!, WinAC, SINUMERIK, and SIMOTION. It also connects to Allen‑Bradley (EtherNet/IP), Mitsubishi (MC TCP/IP), and Modicon (Modbus TCP/IP). Upload/download occurs via Ethernet or USB memory. The panel supports 10 online languages and 32 project languages, easing multi-site deployments.
Selection Guide & Purchasing Advice
Before purchasing the Siemens 6AV2123-2DB03-0AX0, verify your existing panel cutout dimensions and power supply. This unit requires WinCC Basic (TIA Portal) V13 or later for configuration. It ships with open‑source software on CD – no additional licenses needed for basic HMI tasks. For a reliable supply, contact PLC Source PRO (operated by ubest101) to ensure genuine Siemens parts with fast delivery. Stock this module alongside USB sticks for recipe transfer.
