Overview Manuals Specifications Application Operating Environment Monitoring & Control

Features:

  • 320×240 pixel resolution; 4 blue levels; analog resistive touch screen; 50,000 h backlight; numeric/alphanumeric/hexadecimal on‑screen keyboards.
  • PPI (point‑to‑point), PPI network, and MPI protocols; no PROFIBUS DP, no Ethernet, no third‑party PLC support.
  • 250 screens, 500 bit messages, 250 variables, 5 languages; configurable with WinCC flexible 2004 Micro; manual backup/restore.
The 6AV6640-0CA01-0AX0 features a 5.7″ STN (Super Twisted Nematic) blue mode LCD. Unlike full‑color TFT displays, this blue mode display shows 4 levels of blue on a dark background. This monochrome design was common in legacy HMI panels and is suitable for applications where color is not required. The resolution is 320 x 240 pixels (QVGA), sufficient for simple machine graphics, text, and numeric displays. The analog resistive touch screen requires pressure to activate and works with a finger or stylus – even when wearing industrial gloves. The on‑screen keyboards (numeric, alphanumeric, hexadecimal) eliminate the need for physical keys, simplifying the front panel design.

The 6AV6640-0CA01-0AX0 is specifically designed to communicate with SIMATIC S7‑200 PLCs. It supports PPI (point‑to‑point), PPI network, and MPI protocols. PPI (Point‑to‑Point Interface) is a Siemens proprietary protocol used for programming and HMI communication with S7‑200 CPUs. The panel can be connected directly to the S7‑200’s RS‑485 port (PPI/MPI) without additional hardware. It does not support PROFIBUS DP, Ethernet, or any third‑party protocols such as Modbus, Allen Bradley, or Mitsubishi.

The 6AV6640-0CA01-0AX0 is marked as a spare part, indicating it is no longer in active production and is intended for maintaining existing installations. It supports up to 250 screens, 500 bit messages (no analog messages), and 250 variables. It has 5 online/runtime languages and 32 project languages. It does not support analog alarms, telegram alarms, or multi‑key operation. The panel has no SD card slot, no USB port, and no Ethernet. Backup and restore are manual only (no automatic transfer).

The 6AV6640-0CA01-0AX0 Siemens Touch Panel may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL)by the manufacturer (OEM).

  • Thermal Constraints: Operates safely within ambient cabinet temperatures from 0°C to +50°C (+32°F to +122°F).
  • Mounting Position: Intended for vertical mounting layouts, allowing a maximum permissible inclination angle of 35° without needing external air cooling systems.
  • Visual Elements: Equipped with a 5.7-inch STN display operating in a monochrome "blue mode" with a native resolution of 320 x 240 pixels.
  • Touch Interface: Uses an analog-resistive touch screen matrix that allows operators to interact with buttons, entry fields, and sliders using hands or industrial gloves.
Description
The 6AV6640-0CA01-0AX0 is a SIMATIC TP 170MICRO touch panel for SIMATIC S7‑200 PLCs. It features a 5.7″ STN blue mode display with 4 blue levels and 320×240 pixel resolution. The backlight MTBF is 50,000 hours at 25°C. The panel has an analog resistive touch screen with numeric, alphanumeric, and hexadecimal keyboards.

When using the 6AV6640-0CA01-0AX0, engineers can create up to 250 screens and manage 500 messages (bit messages only). It supports 5 online/runtime languages and 32 project languages. The panel has 250 variables per device and 20 variables per screen. It supports PPI (point‑to‑point) and MPI networks for connection to S7‑200 PLCs. 

The 6AV6640-0CA01-0AX0 has a maximum permissible angle of inclination of 35° without external ventilation. It has no function keys or system keys – only the touch screen and on‑screen keyboards. It supports up to 500 text elements and 500 icons. It has 20 I/O fields per image and 20 date/time fields per image. 

For legacy S7‑200 system upgrades or repairs, the 6AV6640-0CA01-0AX0 is a critical spare part. It is configurable with WinCC flexible 2004 Micro (not TIA Portal). The panel has no SD card slot, no USB port, and no Ethernet. It supports first/last value message logging and acknowledgment groups. The touch screen calibration function is available.
