A-B 1734-IE4С REV H Digital Qutput Termination

Product Detailed Description

• Core Function: The EtherNet/IP adapter acts as a communication bridge between the high-speed EtherNet/IP industrial network and the modular POINT I/O backplane. It aggregates the I/O data from all connected POINT I/O modules (digital, analog, specialty, safety) and exchanges this data with the controller over EtherNet/IP.

• Modular System: POINT I/O is a highly modular and compact I/O platform. The adapter connects to a power supply module and then to a series of I/O modules (up to 8, 16, or more depending on the adapter type and power requirements) that snap onto a common backplane.

• Communication Protocol: Utilizes EtherNet/IP, an open industrial Ethernet network that uses standard Ethernet technology (IEEE 802.3 and TCP/IP suite) with the Common Industrial Protocol (CIP) for I/O, messaging, and configuration. This provides high-speed, deterministic, and flexible communication.

• Network Features:

• Dual Ethernet Ports (DLR): Many modern POINT I/O EtherNet/IP adapters feature two Ethernet ports, supporting Device Level Ring (DLR) topology for network redundancy, enhancing system uptime.

• CIP Sync: Supports CIP Sync for precise time synchronization across the network, crucial for coordinated motion and high-speed applications.

• Built-in Web Server: Some adapters include an embedded web server for basic configuration, diagnostics, and monitoring via a standard web browser.

• Diagnostic Capabilities: Provides extensive diagnostic information about the adapter itself, the power supply, and each connected I/O module, facilitating troubleshooting.

• Configuration: Typically configured using Rockwell Software Studio 5000 Logix Designer (for Logix controllers) or Rockwell Software RSLinx Classic/Enterprise.

Product Parameters

(Note: Specific part numbers for POINT I/O EtherNet/IP adapters include models like 1734-AENT, 1734-AENTR. The parameters below are general for these types of adapters, and you should always refer to the specific datasheet for the exact model.)

• Network Protocol: EtherNet/IP (CIP)

• Number of Ethernet Ports: 1 or 2 (for DLR capability)

• Ethernet Connection: RJ45

• Data Rate: 10/100 Mbps (auto-negotiation)

• Power Supply (for adapter itself): Typically 24V DC nominal (range: 10-28V DC or 10-30V DC depending on model)

• Current Draw: Varies by model, typically 100-300 mA (adapter only, excluding I/O modules)

• Max Number of I/O Modules: Typically up to 8, 16, or more I/O modules per adapter (varies by adapter model and backplane current capability).

• Backplane Current: Limited by the adapter and power supply module (e.g., 1000mA or 1500mA for I/O modules).

• Module Capacity: Up to 256 digital points or 128 analog channels per adapter (depending on module types).

• Status Indicators: LEDs for network status (LINK, ACT), module status (MODULE STATUS), power (PWR), and fault (FAULT).

• Operating Temperature: Typically 0 °C to 60 °C (32 °F to 140 °F)

• Storage Temperature: Typically -40 °C to 85 °C (-40 °F to 185 °F)

• Humidity: 5-95% non-condensing

• Mounting: DIN rail mountable

• Certifications: UL, c-UL, CE, RCM, ATEX/IECEx (for hazardous locations, depending on specific model and configuration).

Product Advantages

• Modularity and Flexibility: POINT I/O's modular design allows users to select only the I/O types and densities needed for a specific application, providing flexibility and cost savings.

• Compact Footprint: The small size of POINT I/O modules saves valuable panel space compared to larger I/O platforms.

• Distributed I/O: Enables I/O to be placed close to sensors and actuators, significantly reducing wiring costs, installation time, and potential for noise interference.

• EtherNet/IP Integration: Seamless integration with Rockwell Automation's Logix controllers and other EtherNet/IP compatible devices, leveraging the benefits of a widely adopted open industrial Ethernet standard.

• Network Redundancy (DLR): Adapters with dual ports support DLR, providing enhanced network uptime and fault tolerance, critical for continuous operations.

• Scalability: Easily expand I/O capacity by adding more modules to the adapter or additional adapters to the network.

• Advanced Diagnostics: Comprehensive diagnostics reduce troubleshooting time and improve system uptime.

• Hot Swappable: Many POINT I/O modules can be hot-swapped without removing power from the adapter, facilitating maintenance and reducing downtime.

Precautions

• Proper Power Sizing: Ensure the selected power supply module (e.g., 1734-PS) can provide sufficient current for all connected I/O modules and the adapter itself. Exceeding the backplane current limit can lead to unpredictable behavior.

• Network Design: Adhere to EtherNet/IP network design best practices, including proper cabling (shielded Ethernet cables for industrial environments), cable lengths, and network topology.

• IP Address Configuration: Correctly configure the IP address of the EtherNet/IP adapter using BOOTP/DHCP or manually. Incorrect IP addressing is a common source of communication issues.

• Studio 5000 Configuration: Ensure the adapter and all connected I/O modules are correctly configured in Studio 5000 Logix Designer (or equivalent software) to match the physical hardware.

• Environmental Conditions: Install the adapter within its specified operating temperature and humidity ranges. Avoid areas with excessive vibration, corrosive atmospheres, or direct exposure to liquids unless using appropriately rated enclosures.

• Grounding: Proper grounding of the adapter and the overall control system is crucial for signal integrity and noise immunity.

• Firmware Compatibility: Ensure the firmware version of the adapter is compatible with the controller and the version of Studio 5000 Logix Designer being used.

• Safety Considerations: For safety applications, ensure that safety-rated POINT I/O modules and safety controllers are used in accordance with relevant safety standards (e.g., ISO 13849, IEC 62061). The standard EtherNet/IP adapter (e.g., 1734-AENT) is not safety-rated for direct connection to safety I/O; a dedicated safety adapter (e.g., 1734-AENTR for GuardLogix) is required for safety over EtherNet/IP (CIP Safety).
