SIMATIC HMI TP1900 Comfort PRO 19-inch Round-Pipe Panel (6AV2124-0UC24-0BX0) CAN Electric — Industrial Automation Parts Supplier

The pipe is a standard 48 mm section, not a Siemens bracket

This order number mounts to a 48 mm round support pipe, the same diameter used across many industrial arm systems. That is the practical difference from the fixed flange versions: the panel is not wedded to one manufacturer’s arm. An existing pipe bracket from a third party can be reused, and when the panel is eventually swapped, the support structure stays put. Siemens also offers adapters where the pipe diameter differs, so the pipe you already have usually decides the part, not the other way round.

Expansion rides on the pipe, beside the glass

Because the interface sits on the support pipe, up to two extension units can be added — housings that carry real operator hardware such as pushbuttons, indicator lights, a handwheel, a key switch or an emergency stop, none of which live on the touch surface. On a large display this is where machine controls actually belong: the operator acts without looking at the screen, through gloves, in a hurry. The touch layer keeps handling configuration and alarms; the bolt-on units handle the few controls that must never depend on the display being lit.

At this size the arm is the expensive part

Almost nine kilograms before the adapter, gland and end plate means the pipe and its load rating dominate the installed cost. The pipe mounting decouples that cost from the panel: a bigger or smaller screen clips to the same run, and the structural spending is made once. Ask for a load rating at your actual reach before comparing panel prices, because correcting an under-rated pipe afterwards costs more than the terminal.

Figures taken from the Siemens product documentation; confirm pipe diameter, adapter and arm rating on the current data sheet before any mechanical work is released.

All three carry the same screen, project memory and engineering software. The choice is mechanical: how the panel reaches the operator, and whether hardware controls will ever be needed beside it. The pipe version reuses an existing bracket; the foot version is for a floor-standing station.

Same diagonal and the same project platform, two different machines — one hangs on a pipe in the production area, the other disappears into an enclosure door. The cabinet version is covered on the TP1900 Comfort (6AV2124-0UC02-0AX1) page.

What the extension units add, and what they do not

Each extension unit brings hardware operator elements — illuminated pushbuttons, an emergency stop, a handwheel, key or selector switches, or simply blank positions for later. They add controls, not screen area; the displayed picture stays 1366 × 768. A plant that wants a start/stop pair reachable without the screen, or a guarded e-stop beside a large HMI, puts them here.

The interface survives the product’s own phase-out

The successor generation, Unified Comfort PRO, keeps the same pipe and extension-unit interface. So the arm and any extension units bought today carry straight over when the panel is eventually replaced — only the panel and the TIA project change, not the mechanical investment. That is the argument for specifying this housing now rather than bolting hardware to a fixed version that has no expansion path at all.

Successor mapping per Siemens product phase-out notice 109994541; the concrete order number is the expandable pipe variant, and the fixed and foot versions map to their own equivalents.

Controllers from the S7-1200, S7-1500 and the older S7-300/400 families all connect — PROFINET natively, MPI or PROFIBUS DP through the serial port — while Modbus TCP/IP and EtherNet/IP cover third-party PLCs. The pipe adapter and any extension units are separate mechanical items and are confirmed together with the panel, because none ship inside the device carton.

Typical uses

• Stations built onto an existing 48 mm support pipe, where only the terminal is being changed.
• Machines that need guarded hardware controls beside a large screen — e-stop, handwheel, pushbuttons — without depending on the glass.
• Like-for-like replacement of an installed TP1900 Comfort PRO pipe version, preserving the bracket and any extension units.

How to order

• Send the order number, quantity, destination country and the support-pipe system you plan to use to sales@can-electric.com.
• Tell us which condition you need; new, new-surplus or refurbished is printed on the quotation rather than left to assumption.
• With the family in phase-out, stock is confirmed order by order; quotations are in USD and shipments leave Hong Kong by DHL.
