6AV6640-0AA00-0AX1 Siemens SIMATIC TD 400C Text Display for S7-200 4-Line Backlit LCD 15 Keys incl. 2.5 m PPI Cable

Product Overview: Siemens 6AV6640-0AA00-0AX1

Parameter Specification
Brand Siemens
Order Number 6AV6640-0AA00-0AX1 (incl. 2.5 m connection cable + mounting accessories + customised faceplate)
Variant Note 6AV6640-0AA00-0AX0 = unit without cable/cut-out template; -AX1 = with cable & mounting kit
Product Name TD 400C – Text Display (Text Terminal)

Application & Fault Scenarios

Typical Uses: Low-cost operator terminal for S7-200-based machines needing alarm texts, setpoint entry and start/stop control without a full touch panel. Mounted in the cabinet door (IP65 front) or used as a handheld unit. Also the standard like-for-like swap when a faded/broken TD 400C fails on site.
Common Field Issues:
  • Display blank / no backlight → check that the PPI plug is fully seated in the CPU port; verify the CPU supplies 24 V to the port and that cable length ≤ 2.5 m (longer runs need external power).
  • "Initialising…" stuck or garbled text → confirm the TD configuration data block exists in the CPU, baud rate/address match the wizard settings, and reload the project from backup.
  • Keys unresponsive or wrong function → faceplate/Keypad Designer layout differs from the actual legend; re-check the key assignment and password-protected SETUP menu (address/baud locked by password).
  • Faint or patchy display → backlight ageing (MTBF ~20,000 h) or low contrast at temperature extremes; replace the unit on long-service machines.

FAQ

Q1: What is 6AV6640-0AA00-0AX1?
A: Siemens TD 400C text display — 3.7" 192×64 backlit LCD (4 lines), 15 keys, RS-485 PPI for S7-200/S7-200CN/S7-200 SMART; supplied with 2.5 m cable and mounting kit.
Q2: Does it need a separate power supply?
A: Not within 2.5 m — it draws 24 V from the S7-200 CPU's PPI port (~120 mA). Longer runs require an external supply.
Q3: Can it be used with S7-1200/1500?
A: No. It connects only to S7-200 family CPUs. For S7-1200/1500 use KTP/TP panels or a PROFINET text solution.
