Siemens HMI Panels

Siemens / HMI panels

Every Comfort Panel article number, the full number decode, and why 2026 matters if you run a first generation Basic Panel.

Siemens has made operator panels for over thirty years across at least four numbering ranges. Working out what you have is often harder than sourcing it.

Which range is yours?

Starts with	Range	Status
6AV3	COROS OP3, OP7, OP17, OP27, OP37, TD17, TP27, TP37	Long obsolete
6AV6 54x / 6AV6 64x	OP and TP 170, 177, 270, 277. MP 270, MP 370, MP 377	Discontinued
6AV6647	Basic Panels 1st generation: KTP400, KTP600, KTP1000, KTP1500	Discontinued
6AV2 123	Basic Panels 2nd generation: KTP400, KTP700, KTP900, KTP1200	Current
6AV2 124	Comfort Panels: KTP400 to TP2200	Current, partly cancelled
6AV2 128	Unified Comfort Panels, MTP series	Current
6AV7	Industrial and panel PCs, IPC477 and IPC677	Mixed

How to read a Comfort Panel number

This decodes fully. Take 6AV2124-0MC01-0AX0.

Part	Meaning
6AV2124	Comfort Panel
0	Input type. 0 is TP touch, 1 is KP key, 2 is KTP touch and key
M	Screen size. See below
C01	Generation. 01 or 02
0AX0	Hardware version. 0AX0 is V1, 0AX1 is V2

Letter	Screen size
D	4 inch
G	7 inch
J	9 inch
M	12 inch
Q	15 inch
U	19 inch
X	22 inch

So 6AV2124-0MC01-0AX0 is a 12 inch touch panel, and 6AV2124-1MC01-0AX0 is the 12 inch key version of the same panel.

Comfort Panels, complete range

From the Siemens Comfort Panels operating instructions.

Panel	Size and type	Article number
KTP400 Comfort	4 in touch and key	6AV2124-2DC01-0AX0
KP700 Comfort	7 in key	6AV2124-1GC01-0AX0
TP700 Comfort	7 in touch	6AV2124-0GC01-0AX0
KP900 Comfort	9 in key	6AV2124-1JC01-0AX0
TP900 Comfort	9 in touch	6AV2124-0JC01-0AX0
KP1200 Comfort	12 in key	6AV2124-1MC01-0AX0
TP1200 Comfort	12 in touch	6AV2124-0MC01-0AX0
KP1500 Comfort V1	15 in key	6AV2124-1QC02-0AX0
KP1500 Comfort V2	15 in key	6AV2124-1QC02-0AX1
TP1500 Comfort V1	15 in touch	6AV2124-0QC02-0AX0
TP1500 Comfort V2	15 in touch	6AV2124-0QC02-0AX1
TP1900 Comfort V1	19 in touch	6AV2124-0UC02-0AX0
TP1900 Comfort V2	19 in touch	6AV2124-0UC02-0AX1
TP2200 Comfort V1	22 in touch	6AV2124-0XC02-0AX0
TP2200 Comfort V2	22 in touch	6AV2124-0XC02-0AX1

V1 and V2 have different dimension drawings. Siemens documents TP1500, TP1900 and TP2200 separately for each version. If you are replacing into an existing cutout on those sizes, the trailing digit matters.

What a Comfort Panel gives you

Taking the TP700 Comfort as the example: 7 inch widescreen TFT, 16 million colours, PROFINET interface, MPI and PROFIBUS DP interface, 12 MB configuration memory, Windows CE 6.0.

Configured from WinCC Comfort V11 or higher. Projects upload and download over the built-in Ethernet or USB interfaces. If your engineering station is on an older WinCC version, check before you buy.

If your Basic Panel starts 6AV6647, read this

Siemens declared the first generation Basic Panels a discontinued product on 1 October 2016. That covers the KTP400, KTP600, KTP1000 and KTP1500.

The spare parts commitment runs ten years from that date. That commitment expires in 2026.

If you are still running a KTP600 or KTP1000 on a production machine, official spares are ending this year. After that the only supply is the secondary market, which is where we operate.

Now is a sensible time to either hold a spare or plan the changeover. We can quote either.

The Siemens product lifecycle

Stage	What it means for you
P.M 300, start of delivery	Available new and actively marketed, typically up to 12 years
P.M 400, phase-out announcement	Still orderable, no longer marketed. The ten year spares commitment starts here
P.M 410, product cancellation	No longer orderable new. Spares only, successor usually named
Discontinuation	Spare parts commitment ends. Secondary market only

The 15 to 22 inch Comfort Panels have had a cancellation notice, with named successors in the Unified Comfort 6AV2128 range.

Legacy panels we have confirmed

Please note. The Comfort Panel table above is complete. The legacy ranges below are a confirmed sample rather than a full catalogue, because the older 6AV3 and 6AV6 ranges are not covered by a single accessible Siemens document. Send us your number and we will confirm it properly.

Article number	Panel
6AV6545-0DA10-0AX0	MP370, 12 inch
6AV6642-0BC01-1AX1	TP 177B DP, 6 inch mono

Successors in the Unified Comfort range

Article number	Notes
6AV2128-3QB06-0AX1	Unified Comfort, successor to the 15 inch Comfort Panels
6AV2128-3QB36-0AX1	Unified Comfort, later successor

Accessories

Article number	Item
6ES7193-4JB00-....	Power supply plug, 2x2 pin, spring terminal
6AV6881-0AS42-....	SIMATIC HMI USB stick
6AV2124-6DJ00-....	Protective film, 4 inch, KTP400 Comfort
6AV2124-6GJ00-....	Protective film, 7 inch, TP700 Comfort
6AV2124-6JJ00-....	Protective film, 9 inch, TP900 Comfort
6AV2124-6MJ00-....	Protective film, 12 inch, TP1200 Comfort
6AV2124-6QJ00-....	Protective film, 15 inch, TP1500 Comfort
6AV2124-6UJ00-....	Protective film, 19 inch, TP1900 Comfort
6AV2124-6XJ00-....	Protective film, 22 inch, TP2200 Comfort

The trailing dots are Siemens own notation for the variant key. Note the protective film numbers follow the same size letter scheme as the panels, so a 12 inch film is 6MJ00 to match the M in the panel number.

The power supply plug is worth noting. A tiny part, it goes missing constantly, and a panel without one cannot be commissioned.

Can you identify my panel from a photo?

Yes. Panel labels are usually on the back and often faded or painted over. Send us a photo of the rear label and the front of the panel.

If the label is gone entirely, tell us the screen size, whether it has keys or is touch only, what it connects to, and roughly how old the machine is. That is normally enough.

What we can supply

Legacy panels. COROS, OP and TP 170 through 277, MP 270, MP 370 and MP 377, and the first generation Basic Panels. Surplus and tested used, since there is no new supply.

Current panels. Basic Panels 2nd generation, the full Comfort Panel range above, and Unified Comfort Panels, quoted new as a distributor with a delivered lead time.

Accessories. Power supply plugs, protective films, USB sticks and mounting hardware.

We also buy panels

If you are replacing a control system, the old panels are worth something even if the machine is scrap. See Sell To Us.

Send us your article numbers

Or a photo if the label is unreadable. On the 15, 19 and 22 inch Comfort Panels include the last digit, because V1 and V2 have different dimensions. Quotes in NZD including GST.
