Display:

• Type: Color TFT (Thin-Film Transistor) LCD
• Size: 6 inches diagonal
• Resolution: 320 x 240 pixels
• Colors: 256 colors

Control:

• Touchscreen: Analog resistive (older technology, but offers good pressure sensitivity)

Performance:

• Processor: ARM, 200 MHz (low-power processor suitable for basic HMI tasks)
• Memory: 2 MB Flash memory for user data and programs, 256 KB RAM

Communication:

• MPI (Multi-Point Interface) for communication with Siemens PLCs
• PROFIBUS DP (Decentralized Peripherals) for industrial networking
• RS232/RS485/RS422 for serial communication with other devices
• Ethernet (10/100 Mbps) for network connectivity
• USB port for programming and data transfer

Functionality:

• Designed to be configured with Siemens WinCC flexible 2005 software (no longer actively supported by Siemens as of October 1, 2023).
• Could be used for various HMI tasks like:
  • Machine monitoring and control
  • Data visualization
  • Operator interface for setting parameters and controlling machine functions
  • Alarm and event notification

Important Considerations:

• Discontinued Product: The Siemens TP177B Color PN/DP is a discontinued product (discontinued on October 1, 2023). While you might find remaining stock from some distributors, Siemens no longer offers support or replacement parts for this model.
• Limited Software Support: The recommended configuration software, WinCC flexible 2005 Standard SP1, is also discontinued. While it might still be functional, you won’t have access to updates or technical support from Siemens.

Alternatives:

If you’re looking for a new HMI for your machine control application, Siemens offers newer HMI models with improved features and functionalities compared to the TP177B. You can find information on these on the Siemens site.

Here are some additional points to consider when choosing a new HMI:

• Display size and resolution: Consider the required level of detail and information for your application.
• Touchscreen technology: Resistive vs. capacitive touchscreens have different advantages and disadvantages.
• Communication capabilities: Ensure the HMI has the necessary ports for connecting to your PLC and other devices.
• Software compatibility: Choose an HMI that is compatible with your preferred programming software.

I hope this information is helpful! Even though the Siemens TP177B is discontinued, this information should help you choose a suitable alternative for your HMI needs.
