Description
Product Introduction & Engineering Value
The 2711-T9C8 delivers a 9-inch color active-matrix TFT display with analog resistive touch input and native Data Highway Plus communication. It is a PanelView Standard 900 terminal designed for direct connection to PLC-5 and SLC systems over DH+ while providing an RS-232 printer port for alarm and event logging.
Powered from a universal 85–264 VAC supply, the unit mounts in the standard 900-series panel cutout and runs applications created in PanelBuilder32. Series E and later hardware offer expanded application memory, making it a practical drop-in when an existing color PanelView 900 fails and the original DH+ application must remain unchanged.

Field Application & The “Trench” Experience
A Midwest automotive stamping plant ran a bank of PanelView 900 terminals on a DH+ trunk for press-line monitoring. One 2711-T9C8 lost its backlight during a weekend shift, freezing the color status screens. The electrician pulled a tested surplus unit from the cage, matched the existing panel cutout, landed the same AC feed and blue-hose DH+ cable, loaded the application from the ATA card, and restored full color graphics before the next production cycle started.
Niche placements that fit this exact model:
- Press-line or transfer-die local operator station still running on a PLC-5 DH+ network.
- Packaging line HMI that requires color status indication and hard-copy alarm printing via the RS-232 port.
- Legacy material-handling console where the original PanelBuilder32 application and 9-inch cutout must be preserved.

Transparency SOP: QA & Testing
Every unit undergoes a complete functional evaluation. The display is checked for uniform color, correct 640 × 480 resolution, and consistent backlight intensity. Touch response is verified across the full 384-cell matrix. The terminal is powered on regulated AC within the 85–264 V range while current draw and heat dissipation are monitored. DH+ network join and node-address communication are confirmed, followed by an RS-232 printer-port loopback test. A representative PanelBuilder32 application is loaded, runtime behavior is observed, and the real-time clock battery is verified. Only units that pass the full sequence are released as New Surplus or Refurbished stock.
The Veteran’s Tech Trap Guide
⚠️ Series memory difference – Pre-Series E terminals have only 240 KB of application memory. Loading a larger Series E application will fail. Always confirm the hardware series before transferring the file.
⚠️ DH+ trunk polarity and termination – Reversing the blue-hose conductors or leaving the network unterminated will prevent the terminal from joining. Verify polarity and install the correct end-of-line resistors.
PRO TIP: The CCF backlight is rated for long life but is not field-replaceable on most units. If the display is dim, plan on a complete terminal swap rather than a backlight repair.
Dynamic FAQ
Q: Is the 2711-T9C8 still available new from Rockwell? A: No. The PanelView Standard 900 family is discontinued. Functional New Surplus and refurbished units are the practical source for direct replacements.
Q: What is the difference in memory between series? A: Pre-Series E hardware provides 240 KB of application memory. Series E and later units increase that to 1008 KB. Match the series to your application size.
Q: Can this terminal communicate with modern ControlLogix controllers? A: Directly over DH+ only if a suitable bridge (for example, a 1756-DHRIO module) is present. Native EtherNet/IP is not supported.
Q: Does the RS-232 port support application download? A: No. The RS-232 port is printer-only. Application transfer is performed via the DH+ port or an ATA memory card.
Q: What warranty and authenticity documentation come with New Surplus or Refurbished stock? A: Units ship with full functional test records, clear origin marking (New Surplus or Refurbished), serial and series identification, and a standard parts-and-workmanship warranty.
