Application Scenarios
A water utility’s remote lift station has run on a PLC-5/40C for nearly two decades. The only local face is a 2711-T10C8X_A mounted on a NEMA 4X door: pump status, wet-well level, alarm acknowledge and a paper tape of every escalation, printed live on the RS-232 printer below it. One morning the backlight is a faint orange glow and the touch film misses the lower-third buttons — the exact spot where the pump-start soft key sits. Rewriting the whole station for a modern Ethernet HMI means new conduit, a PLC-5 Ethernet interface that is itself obsolete, and a re-validation the utility has no budget for.
The fix is a same-model exchange. A 2711-T10C8X_A (or a later Series A/B unit accepted by the firmware) goes through the same 375 × 224 mm cutout, the DH+ tap is reused with its existing 1784-TPR drop and 75-ohm terminator, and the .PBA is downloaded from the station’s backup set over the serial port. The printer picks up on page one, the alarm timestamps are whole again, and the operator’s finger lands where it always did. No new network, no new PLC, no new training. That is the product’s entire reason to exist in 2026.
Parameter
| Main Parameters | Value / Description |
|---|---|
| Product Model | 2711-T10C8X_A (2711-T10C8, Series A / Rev A; the “X” is the Series A revision designator on the nameplate) |
| Manufacturer | Allen-Bradley, Rockwell Automation |
| Product Category | Graphic operator terminal, PanelView Standard 1000 family, touch-only input |
| Display | 10.4 in. color active-matrix TFT, 640 × 480 VGA, 4:3, 211 × 158 mm (8.3 × 6.2 in.) viewable — the original PanelBuilder32 grid, no rescale needed |
| Color / Backlight | Color STN/TFT with CCFL backlight, field-replaceable, 50,000 h half-life at 25 °C — and the single most common reason a 2711-T10C8X_A is swapped |
| Touch Technology | Analog resistive, ~100 g actuation force, 1 million press rating — finger, glove or stylus, no calibration drift from moisture |
| Memory | 1008 KB internal nonvolatile flash for the application, ~310 KB runtime/application workspace; expansion via ATA flash memory card — enough for a single-machine panel, tight for a plant-wide project |
| Communication Port A | DH+ (Data Highway Plus), 57.6 kbit/s or 115.2 kbit/s, 3-wire trunk, multidrop to PLC-5/SLC 500. This is the “8” in the catalog number and the reason the model is still specified |
| Communication Port 0 | RS-232 (DB9), Channel 0 — alarm printer, ASCII device, laptop upload/download or a DF1 point-to-point link |
| Power | 85–264 VAC, 47–63 Hz, 55 VA max (≈39 W, 132 BTU/hr); 120/240 VAC global input, no 24 VDC variant of this number |
| Indicators / Clock | Battery-backed real-time clock for alarm timestamps, field-replaceable cell; status LEDs on the bezel for DH+ link and terminal health |
| Mechanical | ≈282 × 375 × 112 mm (11.1 × 14.8 × 4.4 in.), 3.2–3.6 kg (7–8 lb); flush-mount horizontal only, 51 mm (2 in.) clearance on all four sides for airflow and cabling |
| Protection | Front bezel NEMA Type 12, 13, 4X (indoor classified) and IP65; chassis rear is IP54 — rating lives or dies with the gasket and the flatness of the cutout |
| Environment | 0 to 55 °C operating, −25 to 70 °C storage, 5–95 % RH non-condensing, 1000 m altitude without derating; 15 G operating shock at 11 ms, 2 G vibration to 2000 Hz |
| Software | PanelBuilder32 (version 3.8x / 3.9x era), 32-bit toolchain; projects are .PBA source and compile into the terminal’s runtime |
| Lifecycle Note | PanelView Standard 2711 fully discontinued by Rockwell (EOL commonly dated 2012); the 2711-T10C8X_A now exists only as tested surplus, remanufactured or repaired stock — and is worth more than its weight because DH+ is hard to replace |
Technical Principles and Innovative Values
Innovation Point 1 — DH+ in the box, not in an adapter. Modern HMIs speak Ethernet; the 2711-T10C8X_A was born speaking Data Highway Plus at the silicon level. DH+ is a token-passing, noise-tolerant multidrop bus that will run for kilometers on Belden 9463 and keep a PLC-5 talking to six panels and a programming port at once. That is a architectural advantage when your controller has no Ethernet module and never will.
Innovation Point 2 — A paper trail you can touch. Channel 0 on the 2711-T10C8X_A is wired as a printer port, and the terminal will push alarm and event text straight to a serial printer. Before electronic audit logs were mandatory, this was how a shift handover stayed honest; in remote utilities and regulated batch cells it is still the cheapest, power-independent evidence that an alarm was seen and acknowledged.
Innovation Point 3 — Field-serviceable optics. The CCFL inverter and lamp assembly on the 2711-T10C8X_A are replaceable from the rear without a new terminal. Contrast that with the LED-backlit Plus 7, where the backlight is soldered to the panel and a dim screen means a whole unit. For a site that stocks one spare lamp and one spare terminal, the math is dramatically better.
Innovation Point 4 — Resistive by conviction. A million-press analog film does not care about a nitrile glove, a wet finger or the fine mist of a washdown bay. The 2711-T10C8X_A trades the swipe-gesture vanity of a phone screen for a target you can hit with a knuckle while holding a lockout tag. On a machine where the wrong soft-button means a real-world motion, that is not a weakness.
Innovation Point 5 — The project travels with the iron. Because the application is stored in the terminal’s own flash and the source is a PanelBuilder32 file, a 2711-T10C8X_A can be swapped and reloaded from a laptop or ATA card in the time it takes to run the DH+ terminator check. There is no runtime license, no activation server, no Windows update between you and a working screen.
Application Cases and Industry Value
Case 1 — Regional water utility, DH+ ring stays intact. A pumping station cluster links five PLC-5 racks over a DH+ trunk, with a 2711-T10C8X_A at each wet-well and a sixth panel at the headworks. When the headworks touch film started double-firing, the utility’s first quote was a PanelView Plus 7 and an Ethernet card for every PLC-5 — four new modules, new cabling, and a full station re-commission. Instead, the maintenance group sourced a tested 2711-T10C8X_A, reloaded the .PBA from the version-controlled backup, and reused the existing 1784-TPR drop. The only work order line item was a new gasket and a DH+ terminator check, because the old one had gone resistive. Pump start/stop acknowledgements were clean within the shift, and the DH+ network — unchanged since 2004 — kept carrying flow and level data. The saving was roughly an order of magnitude against the Ethernet migration, and the change-control file was three pages instead of a binder.
Case 2 — Tire-cure press, printer-bill audit trail. A tire plant runs a 10.4-inch PanelView 1000 as the operator face of a PLC-5-controlled cure press. Every mold-temperature excursion and interlock release prints on a serial ticket that rides with the batch card. When the original terminal’s CCFL failed at 03:00, the night lead swapped in a 2711-T10C8X_A from the store, reloaded the application from the ATA card and taped a fresh ribbon into the printer. The press was back inside the cure cycle, and the ticket tape never knew the terminal had died. The plant engineer’s note was the kind that sells spare parts: “We didn’t modernize anything. We didn’t have to.” For asset managers sitting on validated, DH+-only cells, the Allen-Bradley 2711-T10C8X_A is not legacy hardware — it is continuity insurance.
Related Product Combination Solutions
| Model | Synergy with 2711-T10C8X_A |
|---|---|
| 2711-T10G8 | Grayscale 10.4″ touch twin with the same DH+ + RS-232 port set. Keep one in the drawer when the original line was spec’d grayscale; the .PBA is portable between C and G, but confirm the color tables before you promise a drop-in. |
| 2711-K10C8 | Keypad-only 10.4″ color sibling. The right spare when the application was built around function-key navigation and a touch film would actually confuse the operator’s trained routine. |
| 2711-T10C9 / 2711-T10C15 | Same chassis with the comm option changed — ControlNet (9) or EtherNet/IP via the 2711-ND7 adapter (15). Quote them only when the controller side is being migrated and the HMI door cutout must stay put. |
| 1784-TPR / 1784-TPS | Right-angle and straight DH+ tap connectors. A 2711-T10C8X_A is only as reliable as its drop; these are the correct termination hardware, and a spare tap belongs in the same box as the terminal. |
| 1747-AIC | Advanced Interface Converter for DH-485 multidrop networks. When the host is an SLC 500 without a DH+ port, the AIC plus the 2711-T10C8X_A‘s DH+ channel is the cleanest bridge — and the first thing to test when the link blinks. |
| 2711-NM14 / 2711-NC13 | ATA memory module and DH+ cable, respectively. The NM14 is how you carry a known-good application to the panel door without a laptop; the NC13 is the DH+ trunk drop you replace pre-emptively with every terminal swap. |
| 2711P-T10C4A9 | The original PanelView Plus 1000 10.4″ it begat. Same door cutout, same 4:3 canvas, Ethernet added — the usual “buy us five more years” stepping stone before a full Plus 7 move. |
| 2711P-T10C22A9P | PanelView Plus 7 Performance 10.4″ AC terminal. The next rung up: dual Ethernet with DLR, LED backlight, FactoryTalk View ME. Only justify it when the PLC-5 is also being retired, because DH+ disappears and the .PBA must be rebuilt. |
