Information About 1788-MCHKR

The 1788-MCHKR forms part of Rockwell Automation’s diagnostic toolset for industrial network maintenance, providing multi-protocol physical media testing in a portable form factor. Its construction includes an LCD display, keypad controls, and multiple connector interfaces, enabling technicians to analyze a wide range of Allen-Bradley network cabling systems. The device features a stored cable library accessible via DB9, helping users select the correct parameters for precise measurement. Typical applications include cable verification during installation, commissioning, and routine maintenance for ControlNet coax, DeviceNet trunk/drop wiring, DH+ coax, RIO wiring, and Ethernet copper links.

Key Features:

  • Multi-network compatibility: Supports ControlNet, DeviceNet, DH+/RIO, and Ethernet media.
  • Cable fault detection: Identifies open circuits, shorts, and wiring errors.
  • Length measurement: Determines approximate cable length for troubleshooting.
  • Wiring integrity checks: Verifies correct pinout and cable continuity.
  • LCD text display: Two-line, 16-character screen for test results and menus.
  • Portable handheld design: Lightweight and battery-powered for field use.
  • Keypad interface: Simplifies navigation and test execution.
  • DB9 stored cable library: Provides preconfigured cable profiles for measurement accuracy.
  • Supports RJ45 and 9-pin interfaces: Enables direct testing of Ethernet and serial-style networks.
  • Battery powered: Operates using two standard AA alkaline batteries.

The 1788-MCHKR delivers the reliability and precision required for rapid network diagnostics in industrial automation systems.

Frequently Asked Questions about 1788-MCHKR
Question: What is the 1788-MCHKR?
Date Update:20/06/2025
Answer:

The 1788-MCHKR is a communication interface module that integrates HART-enabled devices into a ControlNet network. It acts as a bridge, enabling a ControlLogix system to read and write HART variables via ControlNet.

Question: Which protocols does the 1788-MCHKR support?
Date Update:20/06/2025
Answer:
  • HART 5 and HART 6
  • ControlNet
  • Works with Allen-Bradley ControlLogix and CompactLogix systems using appropriate network bridges.
Question: How is the 1788-MCHKR configured?
Date Update:20/06/2025
Answer:
  • Configuration is performed using:
    RSLogix 5000/Studio 5000
    EDS file for module recognition
  • HART variables (PV, SV, TV, QV) are mapped into controller tags
  • Supports automatic HART device detection and pass-through to asset management tools
Question: What are the power and wiring requirements?
Date Update:20/06/2025
Answer:
  • Powered through the ControlNet or external power supply depending on chassis
  • HART wiring uses standard two-wire loop, which can be:
    Internal power (provided by the module)
    External power (field-provided)
  • Requires termination resistors (typically 250 ohms per loop)
Question: What are the environmental conditions for operation?
Date Update:20/06/2025
Answer:
  • Operating Temperature: 0 to 60°C (32 to 140°F)
  • Storage Temperature: -40 to 85°C (-40 to 185°F)
  • Humidity: 5% to 95% non-condensing
  • Vibration: Meets IEC 60068-2 standards
