Physical and Electrical Specifications

EtherNet/IP Deterministic Networks & Firmware Flash Execution

The unit integrates dual Ethernet interfaces designed for IEEE 802.3 networks, operating seamlessly on EtherNet/IP deterministic networks to deliver sub-millisecond status synchronization with Logix controllers. System reliability relies on firmware flash compatibility, allowing firmware images stored in non-volatile flash memory to match runtime controller revisions without communication overhead. Built-in media redundancy via DLR protocol guarantees continuous data transfer across ring topologies if a physical cable breaks.

Included Hardware and Accessories

• 1 x Allen-Bradley 2711P-T12W22D9P HMI Terminal
• 1 x 2-Pin Removable DC Power Terminal Block Connector
• 8 x Heavy-Duty Mounting Levers and Clamps
• 1 x Panel Cutout Template and Reference Document

Mechanical Installation and Power Wiring Requirements

• Panel Cutout Execution

  Prepare the enclosure opening using the supplied template. Ensure cut edges are deburred to allow the perimeter elastomeric seal to fit flush against the outer enclosure face.

• Mounting Lever Torque Limits

  Position the module into the panel opening. Attach the eight mounting levers around the chassis housing and torque each screw strictly to 0.9-1.1 Nm to maintain the IP66 water-tight seal without causing frame warping.

• DC Electrical Wiring Setup

  Strip 24 VDC supply conductors to 7 mm. Connect positive and negative conductors to the two-terminal DC plug using 14-18 AWG copper wire, keeping voltage supply limits strictly within 18 to 30 VDC.

• Functional Shield Grounding

  Run a low-impedance copper ground braid from the dedicated grounding stud on the rear metal frame directly to the primary system earth bus to suppress electrostatic discharges.

Technical Support FAQs

• What happens if input voltage drops below the 18 VDC operating threshold?

  The internal power circuit triggers a low-voltage brownout shutdown to prevent file corruption in non-volatile flash memory, requiring voltage restoration above 18 VDC to reboot.

• Can the dual Ethernet ports be configured with separate IP subnets?

  No, the integrated switch hardware routes traffic through a single internal network interface card; both ports share the identical IP address for ring redundancy or daisy-chaining.

• What thermal clearance is required around the rear chassis cooling vents?

  Maintain a minimum clearance distance of 51 mm on all sides of the rear chassis to ensure adequate free convective airflow and prevent processor thermal throttling.

• Does the front resistive touch glass support operation with industrial gloves?

  Yes, the analog resistive surface senses physical force rather than capacitance, allowing operation with standard industrial leather, rubber, or synthetic work gloves.

• Is hot-swapping the DC power connector permitted during active control sequences?

  Unplugging the live DC power connector causes immediate power termination and is strictly prohibited in hazardous areas due to electrical arc hazards.

• How is non-volatile application data backed up without network connections?

  Application runtime files, alarm logs, and trend archives can be exported directly to an external FAT32-formatted SD card via the integrated rear expansion slot.

• What maximum cable length is supported for standard Cat5e Ethernet runs?

  The physical layer specification limits total cable distance between the terminal port and an adjacent switch node to 100 meters without active signal repeaters.

• How does firmware flash compatibility affect controller tag communication?

  Matching firmware versions ensures the terminal correctly decodes symbolic tag structures from Logix controllers without manual tag mapping or translation tables.
