Modbus TCP/IP is an industrial communication protocol that uses Ethernet or Wireless TCP/IP or UDP connections to enable data to be sent in between devices.  Switching to a more common IP based network connection enables faster, longer range, and more reliable connection between a host PC and the Modbus Slave device itself.

LabJack offers laboratory grade, industrial spec. computer based data acquisition (DAQ) hardware and control products. Our products are powerful, yet affordable; multifunction tools to equip engineers to solve challenges, and unlock insights.  "LabJacks" can be easily integrated into larger systems via the Modbus TCP protocol.  LabJacks T-Series devices (T4, T7) are implemented as Modbus Slaves or Servers that expose a set of Registers that can be read or written to by sending Modbus packets over both TCP and UDP connections.

Why LabJack

Legendary Support

  • Email responses that actually answer your question.
  • Free lifetime support includes (some) engineering design help.
  • The engineers who made the product also respond to your questions.
  • Should your LabJack misbehave, we offer free RMA diagnostics & repairs.

Flexibility

  • Software integrates easily. We don't force you into a certain software, programming environment or operating system.
    • LabVIEW, C++, MATLAB, Python, Java, .NET, Delphi, Visual Basic, VB6, VBA, and more
    • Windows, Mac OS X*, Linux*
  • Add new kinds of sensors on-the-fly. We provide inexpensive signal conditioning modules.
  • Control valves, motors, lights, pumps, etc - using one of many digital I/O control options.
  • Incorporate LabJack DAQ hardware using our OEM options.

Quality Hardware

  • Have confidence in your measurements. Every device is individually tested and calibrated.
  • New features and updates are readily available through field-programmable firmware.
  • Multiple protection mechanisms on every I/O to help prevent electrical damage. 

* Not all platforms are fully supported for each device, see our LabJack Applications, Example Code/Wrappers, and Installer Downloads pages for more details.  Our T-Series devices (T4, T7) have the best cross platform support.
