Siemens 6AV6641-0BA11-0AX1 SIMATIC KTP600 Basic Color DP – 5.7″ TFT Touch + 6 Keys, MPI/PROFIBUS DP, 24 V DC HMI

Product Overview

The Siemens 6AV6641-0BA11-0AX1 is a SIMATIC HMI KTP600 Basic Color DP – the PROFIBUS DP / MPI variant of Siemens' first-generation KTP600 Basic panel, featuring a 5.7-inch TFT display with 256 colours, resistive touch screen and six freely configurable tactile function keys. Within the SIMATIC HMI tiers, the KTP600 Basic series sits at the entry level beneath the Comfort panels (6AV2124…) and beneath the second-generation Basic panels (6AV6647…), targeting small-to-medium machine-level visualisation where a 10" or 15" panel would be overspecified and a pure-text OP/TP170 would feel underpowered. The Siemens 6AV6641-0BA11-0AX1 specifically addresses the DP/MPI market: its RS485/422 interface carries MPI (to S7-300 CPU integrated port) and PROFIBUS DP (to DP-V1 masters), making it the natural HMI companion for S7-1200 + CM1243-5 DP-master setups and for S7-300 legacy lines that never migrated to PROFINET. It is not a PROFINET panel – that is the -0AA11-0AX1 PN sibling – so specifying the correct suffix matters at procurement.

Configuration is handled through SIMATIC WinCC Flexible 2008 Compact or through the HMI portion of STEP 7 Basic bundled with S7-1200 engineering, supporting up to ~500 tags, alarm buffers, trend curves and recipe pages suitable for small-machine scopes. The Siemens 6AV6641-0BA11-0AX1 carries 512 KB user memory, a 320 × 240 pixel 5.7" TFT (4:3 aspect, matching the TP177micro / TP177A footprint it was designed to succeed), six tactile keys with LED-capable grouping, and a resistive analog touch layer that works with gloves – a detail that matters on shop-floor machines where operators don't remove work gloves to press screens. Front protection is IP65, rear is IP20, supply is 24 V DC (19.2–28.8 V), and the door cut-out (197 × 141 mm) matches the TP177micro exactly, which is why many Siemens 6AV6641-0BA11-0AX1 purchases are framed as TP177 replacements on ageing lines.

Siemens has since moved the Basic portfolio to the second-generation 6AV6647-… (KTP600 Basic Color DP -0AC11-, PN -0AD11-) with a slightly larger 480 × 272 resolution on PN variants and updated firmware, and longer-term to the 6AV2123 KTP700/900 Basic (7"/9", 16:9, TIA Portal native). The Siemens 6AV6641-0BA11-0AX1 is therefore spare-part status today, procured almost exclusively for like-for-like swaps on validated WinCC Flexible projects, for TP177micro upgrade-retrofits that must keep the 5.7" 4:3 cut-out, and for S7-300 DP-line spares banks where introducing a PROFINET-only HMI would force a network re-layout. We supply the Siemens 6AV6641-0BA11-0AX1 as new-surplus, refurbished-tested or used-tested, with WinCC Flexible transfer verification before dispatch to guarantee the DP/MPI handshake works on arrival.

Main Features and Advantages

DP/MPI native for S7-300 and S7-1200+CM1243-5: The defining trait of the Siemens 6AV6641-0BA11-0AX1 is its RS485/422 port wired for MPI and PROFIBUS DP, not PROFINET. On plants where the PLC backbone is still MPI (S7-300 integrated X1 port at 187.5 kbps–1.5 Mbps) or a DP-V1 segment (S7-300/400 with DP master modules, or S7-1200 with CM1243-5), dropping in a PROFINET-only HMI forces either a CP card addition or a PLC-network redo. The Siemens 6AV6641-0BA11-0AX1 rides the existing bus unchanged – pinning to the DP connector, respecting the terminator resistors at segment ends, and inheriting the same station address the old TP177micro used. For small-machine OEMs still shipping S7-1200 + CM1243-5 DP-master skids into DP-dominated plants, the Siemens 6AV6641-0BA11-0AX1 remains the correct HMI spec.

Touch + keys hybrid ergonomics: Pure touch panels force operators to hunt on-screen buttons while wearing work gloves; pure key panels limit screen navigation to fixed physical layouts. The Siemens 6AV6641-0BA11-0AX1 splits the difference – six tactile keys below the 5.7″ TFT handle acknowledge, reset, auto/manual toggle, recipe prev/next and emergency-style actions that the operator wants muscle-memory for, while the resistive touch covers parameter entry fields, alarm list scrolling and faceplate pop-ups. The resistive layer works with gloved fingers (unlike many PCAP panels), which is why the KTP600 Basic series kept resistive even as higher tiers moved capacitive. In stamping, injection moulding auxiliaries and packaging infeed stations, that glove-compatibility keeps the Siemens 6AV6641-0BA11-0AX1 relevant against newer panels.

Right-sized for small-machine budgets and cut-outs: At 5.7″, the Siemens 6AV6641-0BA11-0AX1 fills the gap between the 3.8″ KTP400 and the 10.4″ KTP1000. The 197 × 141 mm cut-out is identical to the TP177micro / TP177A it succeeded, so panel swaps on ten-year-old machine doors need no re-cut. 512 KB memory and ~500-tag licensing cover alarm buffers (discrete + analog), 4–8 trend curves, a handful of recipes and a multi-language label set (5 online / 32 config languages in WinCC Flexible), which is exactly what a standalone packing machine, capping turret, small press or pump skid needs – no more, no less. Overspecifying a TP700 Comfort on these machines wastes both panel cost and cabinet depth; underspecifying a KTP400 cramps the recipe grid. The Siemens 6AV6641-0BA11-0AX1 lands the middle.

Maintenance-friendly legacy workflow: The Siemens 6AV6641-0BA11-0AX1 supports ProSave on the PC side for backup/restore of configuration, OS image, data records and calibration, transferred over the MPI/DP cable (no separate Ethernet needed). No battery is required for retentive data – the panel uses non-volatile memory for recipes and alarms, removing the “battery dead → lost recipes” failure mode that plagued older OP/TP170 units. Contrast and touch calibration are accessible from a clean-screen password menu on the panel itself, letting maintenance swap a Siemens 6AV6641-0BA11-0AX1 in, restore the .hmi archive via ProSave over MPI/DP, calibrate once, and hand back to production the same shift.

Lifecycle clarity: We don’t pretend the Siemens 6AV6641-0BA11-0AX1 is a forward-spec – it’s a preservation buy. The second-gen successor is 6AV6647-0AC11-3AX0 (KTP600 Basic Color DP, 6AV6647 generation, same 5.7″ but different internal firmware revision, still WinCC Flexible compatible), and the TIA-Portal-native migration is 6AV2123-2MB03-0AX0 (KTP700 Basic PN, 7″, 16:9, cut-out changes). For buyers who must keep WinCC Flexible and the 5.7″ 4:3 door, the Siemens 6AV6641-0BA11-0AX1 is the correct SKU; for those ready to move to TIA Portal, we flag the KTP700 Basic path at quotation.
