Installation Guide Step by Step Setup for the TP 177B DP Panel

Setting up the Siemens TP 177B DP operator panel (6AV6642-0BC01-1AX1) is straightforward if you follow these key steps carefully. Here’s how to ensure a smooth installation.

Mounting and Cutout Preparation

• Panel Cutout Size: Prepare a mounting cutout of 144 mm x 144 mm in your control cabinet door or panel board.
• Mounting Depth: Make sure you have at least 80 mm behind the panel for cable connections.
• Fixing the Panel: Use the supplied mounting clamps to securely attach the panel to the cutout from behind. Check that it sits flush and stable.

Wiring PROFIBUS Chain Topology

• Connection Type: The TP 177B DP communicates via PROFIBUS DP. Always wire it in a daisy-chain (chain) topology.
• Termination: Make sure PROFIBUS termination resistors are installed only at the start and end of the cable chain.
• Cabling: Use shielded twisted pair cables designed for PROFIBUS and ground the cable shield properly to avoid noise.
• Power Supply: Connect a stable 24 V DC supply within ±10% tolerance to avoid voltage dips.
• Grounding: Properly ground the panel chassis and shields to minimize electrical interference.

Software Configuration with WinCC Flexible

• Project Setup: Open WinCC flexible and create a new project specifying the TP 177B DP as your target device.
• Communication Setup: Configure the PROFIBUS address matching your PLC network setup (usually set in the hardware config on the PLC).
• Screen Design: Add process screens, buttons, and animations per your HMI needs.
• Download to Panel: Connect the panel’s USB port or MPI/PROFIBUS port to your PC and download the project.

Testing and USB Diagnostics

• Initial Power-On: Power the panel and confirm the startup logo appears and no error messages show.
• Diagnostics: Use the USB service port for firmware updates and diagnostics. Siemens software like SIMATIC Manager or WinCC can help check PROFIBUS communication.
• Test Communication: Confirm the panel exchanges data with your PLC and all controls respond.
• Touchscreen Test: Verify touch functionality across the entire display.

Tips to Avoid Voltage Issues and Needed Tools

• Stable Power Source: Avoid connecting the panel to noisy power supplies or those with frequent dips.
• Use Ferrite Cores: If interference is suspected on PROFIBUS cables, adding ferrite cores can help.
• Tools Required: Wire stripper, crimp tool, multimeter (for voltage and continuity checks), and PC with WinCC flexible installed.
• Check Cable Length: PROFIBUS cables over 1000 meters may require repeaters; stay within recommended lengths.

Following these steps guarantees a reliable installation of the TP 177B DP operator panel. For visual aid, refer to Siemens’ official installation diagrams, which show precise cutout dimensions and wiring setups.
