The Siemens 6AV6642-0BC01-1AX0 is the SIMATIC TP 177B DP Touch Panel with a 5.7" blue mode STN display of 320 x 240 pixels. The panel is operated by touch, runs on 24 V DC and communicates via MPI or PROFIBUS-DP; it has RS485/RS422 and USB connections, a printer interface and a slot for an MMC memory card. According to the product data the memory is 2048 kbyte. The panels of the SIMATIC HMI 170 series show process data and operating elements directly at the machine; an identical replacement panel takes over the existing project. According to the product data the type is no longer available; 6AV6642-0BC01-1AX1 is named as its successor. When replacing, mount the panel in the same cut-out, carry over the supply and bus cable, load the project with the engineering software and after switching on check the display and the touch operation.

Problems with 6av6642-0bc01-1ax0: screen dark or backlight weak
A screen that keeps getting darker or is only readable with a torch has a worn backlight; on older panels (OP, TP, MP) that is a CCFL tube, on newer ones LEDs. A screen that stays off while the panel still communicates points to the backlight supply or inverter. Both are replaced in a refurbishment; a refurbished panel usually costs less than a single repair plus the downtime.
6av6642-0bc01-1ax0: touch does not respond or responds in the wrong spot
If the touch screen responds offset, recalibrate it first (Control Panel or Loader, touch calibration). Dead zones, ghost touches or a corner that no longer responds are a worn touch foil; that is replaced in a refurbishment. On key panels (OP, keypad) worn membrane keys are the equivalent.
6av6642-0bc01-1ax0 starts in the Loader or shows no project
If the panel starts in the Loader (Transfer, Start, Control Panel) without opening the project, the project is no longer present or is corrupted. Download it again from WinCC flexible, WinCC or TIA Portal, or restore a backup with ProSave. Without the project file this cannot be recovered: always keep a backup of every panel in the installation.
6av6642-0bc01-1ax0: #### in the fields or connection to the PLC lost
Hashes in the fields mean the panel does not get its tags from the PLC. Check the connection settings (PROFIBUS address and baud rate, or IP address and rack/slot), the cable and whether the PLC is in RUN. After replacing the panel the same connection settings must be in the project and the project's runtime version must match the panel type.
Fault not fixed: replace, exchange or repair the 6av6642-0bc01-1ax0?
Replacing from stock is the fastest route when a machine is down. Van Haelen supplies the 6av6642-0bc01-1ax0 refurbished (tested, with a test report per serial number) or new in factory packaging, with a 24-month warranty. The current lead time is shown with the condition on this page. Prefer an exchange: you get a refurbished unit straight away and return the faulty one within 14 days. Repairing your own unit is also possible: diagnosis, then a fixed price.
What information should I send for a quick diagnosis?
A photo of the rating plate (order number, product version, firmware), the exact fault code or LED state, when the fault occurs (at power-up, on enable, under load) and what you have already tried. For PLCs an export of the diagnostic buffer, for drives the parameter set. With that we can usually say the same day whether replacing, exchanging or repairing is best.
