Remote Assistance and Monitoring: A Checklist to Prevent Downtime Upon Return

In the world of industrial automation, getting a system back online often depends on the ability to respond quickly, before a minor alarm turns into a costly machine shutdown. Remote support, combined with continuous monitoring, has become the first line of defense. In this article, we offer a practical checklist—enhanced by Mect solutions—to ensure that when workers return to the factory, the machines are operational, safe, and ready to produce.


1. Checking Network Connectivity

  • Check the status of the interfaces (Ethernet, Wi-Fi, 4G) and latency.
  • Ping tests to critical devices to confirm connectivity.
  • Mect sMily provides a real-time overview of connectivity, with automatic alerts when the connection drops, allowing you to take action before the problem spreads.

2. Status of Sensors and I/O Modules

  • Verification of temperature, pressure, and current values against operating thresholds.
  • Check the digital inputs/outputs (0–24 V) to ensure there are no short circuits or abnormal signals.
  • The 19-inch Linux Web Panel (WEBP4190), with its 8 configurable GPIO lines, allows you to view all I/O signals on a single screen, with integrated trend graphs powered by Grafana and InfluxDB.

3. Log Storage and Integrity

  • Make sure the overlay file system is enabled (default on WEBP4190) to protect the logs from unexpected shutdowns.
  • Check for alarm logs , PLC event logs, and diagnostic messages.
  • With Mect Suite SDK , you can create custom scripts in Python or C/C++ that automatically extract logs and send them to the cloud via MQTT or OPC-UA.

4. Firmware and Application Updates

  • Check the current firmware version of the PLCs, HMIs, and panels.
  • Schedule the installation of critical updates during maintenance windows.
  • Thanks to sMily, updates can be deployed remotely, with built-in checksum verification to prevent corrupted installations.

5. Monitoring System Resources

  • Monitor CPU, RAM, and eMMC memory usage to identify bottlenecks.
  • On the WEBP4190, the Linux kernel with real-time support alerts you to any spikes in usage that could compromise the HMI's responsiveness.
  • Use Node-RED or Python scripts to set alarm thresholds and configure notifications via email or instant messaging.

6. Security and Access

  • Verify that remote access credentials (VPN, SSH, certificates) are up to date and have not expired.
  • Check the access logs to detect intrusion attempts.
  • Mect Suite allows you to manage users with different roles, restricting access to authorized personnel only.

7. Emergency Response Drill

  • Perform a fault simulation (e.g., loss of sensor signal) to verify that the remote assistance procedures are triggered automatically.
  • Confirm that the support team receives the alert, logs into the system via sMily, and initiates the resolution process.

8. Documentation and Communication

  • Update the maintenance log with the tasks performed during the inspection.
  • Send a summary report to the production manager, including any corrective actions.
  • Mect's "Request a Quote" form can be used to request a personalized consultation or a demo of the new monitoring features.

How Mect Solutions Make Checklists More Effective
