SIMATIC HMI TP1200 Comfort PRO 12-inch Support Arm Panel PROFINET and PROFIBUS (6AV2124-0MC24-0AX0) CAN Electric — Industrial Automation Parts Supplier

What is 6AV2124-0MC24-0AX0?

It is the SIMATIC HMI TP1200 Comfort PRO 12-inch Support Arm Panel PROFINET and PROFIBUS — a 12-inch Comfort Panel PRO with a 1280 × 800 widescreen TFT, projective-capacitive touch operation on a scratch-resistant glass front, PROFINET plus MPI/PROFIBUS DP interfaces, 24 MB configuration memory, Windows Embedded Compact 2013, designed for support-arm mounting with a top flange and engineered with WinCC Comfort V14 SP1 with HSP.

Is this panel the same as the TP1200 Comfort?

No. The standard TP1200 Comfort (6AV2124-0MC01-0AX0) is recessed into an enclosure door and fixed with clamps behind the plate. This PRO device mounts on a support arm with a flange on top, carries 24 MB instead of 12 MB of configuration memory, runs WEC 2013 instead of Windows CE 6.0, and needs WinCC Comfort V14 SP1 with HSP instead of V11.

Is this panel discontinued?

Siemens lists it as PM400 — product phase-out announced, effective 3 February 2026, with 6AV2128-3MB27-0AX0 (Unified Comfort PRO) as the named successor. It can still be sourced while stocks last, but the successor is a Unified panel, so moving to it means migrating the project to WinCC Unified. Some distributor pages still show this item as active; that data is out of date.

What is the difference between 0AX0, 0BX0 and 1AX0?

Mounting and expandability only. 0AX0 is a support arm with the flange on top and is not expandable. 0BX0 is a support arm for a round pipe and is expandable. 1AX0 is a supporting foot with the flange at the bottom and is expandable. Display, interfaces and memory are identical, so the HMI project does not change between them.

Does it need a panel cut-out?

No. It is mounted on a support arm through the top flange, so there is no cut-out in an enclosure door and no mounting clamps behind a plate. The support arm and the flange interface are separate mechanical items — tell us which arm you plan to use and we will confirm the matching flange or adapter.

Can I add a keypad or handwheel to it?

Not to this order number — it is the non-expandable variant. If you need extension units, order 6AV2124-0MC24-0BX0 (round-pipe support arm, expandable) or 6AV2124-0MC24-1AX0 (supporting foot, expandable) instead.

Which software do I need to configure it?

The TIA Portal with WinCC Comfort V14 SP1 and the HSP. It is not configured with WinCC Basic (Basic Panels) or WinCC Unified (Unified Comfort / Unified Comfort PRO panels). A project written for an older Comfort panel version should be checked against V14 SP1 before download.

How much configuration memory does it have?

24 MB, twice the 12 MB of the standard TP1200 Comfort. Two SD card slots are available for archiving, recipes and project storage on top of that.

Is the touch screen capacitive or resistive?

It is a projective-capacitive touch screen behind a non-reflecting glass front. The glass is scratch-resistant and chemical-resistant, and the panel is specified for operation with gloves. Resistive touch is used on the standard Comfort Panels and on the Basic Panels, not on the PRO devices.

Does it have PROFINET and PROFIBUS?

Both. It has two Industrial Ethernet PROFINET ports with an integrated switch and one RS-422/485 interface for MPI/PROFIBUS DP, so the same panel can serve a PROFINET line and a legacy PROFIBUS segment.

What power supply does it need?

24 V DC with a permissible range of 19.2 – 28.8 V DC. The rated current is 1.5 A and the typical power input is 36 W. Size the supply with headroom for the inrush current (I²t 0.5 A²s) and, where Extension Units are fitted, for their additional load.

What is the operating temperature range?

0 °C to +45 °C in vertical mounting; the permissible range depends on the mounting angle, so check the data sheet for your installation position before specifying the enclosure or arm location.

Is it suitable for washdown or outdoor use?

The housing is totally IP65 protected — front and rear — with NEMA 4 / 4X at the front, because these devices are designed for cabinet-free machine mounting. That suits washdown and splash zones on a normal plant floor. For outdoor, UV-exposed, wide-temperature or hazardous-area installation, the Outdoor Comfort variants are the correct choice rather than this device.

Is the panel genuine and new?

We supply genuine Siemens hardware sourced through established channels. Condition (new, new-surplus or refurbished) is stated on every quote, and units are inspected before dispatch.

Is CAN Electric an authorized Siemens distributor?

No — we are an independent channel trader, not Siemens. We source genuine Siemens products through Siemens-authorized distribution partners and confirm condition and delivery on your quote.

How do I get a quote and how is it shipped?

Email sales@can-electric.com with the order number, the support arm you intend to use, the condition you need and the delivery country. We confirm availability and terms per order and quote in USD; shipment is from Hong Kong via DHL worldwide, with packaging and lead time confirmed on each quote.
