How To Collect, Visualize, and Monitor LabJack Data with Machinechat JEDI using Modbus-TCP Protocol

Introduction

This guide provides step-by-step instructions and video walkthroughs to: * Connect one or more LabJack T4, T7, or T8 devices to Machinechat JEDI. * Create dashboards to visualize LabJack data. * Set up controls to send data to LabJack devices, and create rules and alerts to monitor LabJack data.

What is LabJack?

LabJack is a versatile data acquisition device that allows users to monitor and control sensors, actuators, and other hardware using communication protocols like Modbus-TCP. Popular models that support Modbus-TCP include the LabJack T4, T7, and T8.

Prerequisites

  • LabJack T4, T7, or T8 data acquisition device
  • Machinechat JEDI
  • Network requirements:
    • A LabJack device connected to the same network as Machinechat JEDI.
    • Ensure the LabJack device's IP address is accessible.

Setting Up LabJack Data Collector in JEDI

To collect data from LabJack device, you need to configure the LabJack data collector in Machinechat JEDI.

Visualizing LabJack Data in JEDI

Visualizing LabJack data in JEDI involves creating dashboards that display real-time and historical data collected from LabJack devices.

Example Use Case

Create a dashboard to monitor temperature

  • Use a LabJack T4 connected to a temperature sensor.
  • Add a line chart to display temperature over time.
  • Add a gauge chart to show real-time temperature values.

Setting Up Controls, Rules, and Actions to Interact with LabJack Data

You can use Machinechat JEDI to send commands to LabJack devices and define rules to send alerts or automate actions based on real-time data.

Example Use Case

Alert on High Temperature

  • Set a rule to send an email alert if the temperature exceeds 95F.
  • Configure the rule to also run an external script when this condition occurs.

Troubleshooting Common Issues

Connection Issues

  • Ensure the LabJack device is powered and connected to the network.
  • Verify the correct IP address and Modbus-TCP port (default: 502).

Data Collection Problems

  • Check the polling interval and ensure it matches the LabJack devices's capabilities and network latencies.
  • Confirm the Modbus registers are configured correctly.

Rule Execution Failures

  • Verify the rule conditions and actions are set up correctly.
  • Check for any conflicts in control commands.
