Proven Application Environments
- Packaging Machinery: Conveyor line HMI for start/stop, speed reference, and fault display on Micro820/Micro830 systems
- HVAC & Building Automation: Compact operator panel for chiller, AHU, and pump control stations
- Food & Beverage: Washdown-rated front panel (IP65) suitable for hygienic zone machine interfaces
- Material Handling: Sorter and palletizer operator terminals with serial PLC connectivity
- OEM Machine Panels: Space-constrained enclosures requiring sub-5″ HMI with native Rockwell protocol support
- Water & Wastewater: Remote pump station operator interface with DH-485 network integration
Engineering Advantages
- Native Rockwell Integration: Plug-and-play compatibility with Micro800 family via Connected Components Workbench — no third-party driver configuration required
- IP65 Front Panel: NEMA 4/4X rated for dust-tight and washdown environments without additional enclosure modification
- Compact Footprint: 4.3″ display in a 138 × 100 mm cutout — ideal for retrofit and space-constrained OEM panels
- Multi-Protocol Serial: Supports DF1, DH-485, and Modbus RTU — enabling connectivity to legacy Allen-Bradley and third-party PLCs
- Low Power Consumption: 24VDC @ 0.5A max — compatible with standard 24V panel power supplies, no dedicated HMI PSU required
- Free Development Software: CCW (Connected Components Workbench) is available at no cost from Rockwell Automation
System Architecture & Signal Flow
The 2711R-T4T operates as a serial HMI terminal in a single-master, point-to-point or multi-drop network topology:
- Controller Layer: Allen-Bradley Micro820 / Micro830 / Micro850 / MicroLogix 1100/1400 via RS-232 (DF1) or RS-485 (DH-485)
- HMI Layer: 2711R-T4T reads/writes controller tags via serial polling — no Ethernet switch or router required
- Power Architecture: Single 24VDC feed to HMI; controller powered independently from same panel bus
- Programming Path: Engineering workstation → USB → 2711R-T4T (CCW project download); controller programmed separately via USB or Ethernet
- Signal Flow: Operator input (touchscreen) → CCW runtime tag → serial write to PLC register → PLC output → field device actuation
