If the PLC is not connected to the Matics network, the machine on the web/app will display a status of “no communication.”
How it works:
If the PLC loses connection to the Matics router for more than 5 minutes, the machine status will change to “no communication."

Troubleshooting Workflow
1. Check PLC Power Supply
Ensure the PLC is connected to power and that the display screen is on.
The PLC power supply is 24V DC.
Verify the voltage is stable and there are no loose connections.
2. Check Wi-Fi Availability
Use your phone near the PLC to check if the network EM-PLC is available.
Verify LED lights are on in the ETH connection - both green\orange are on
Ensure the signal is strong, not weak or poor.
If the Matics Wi-Fi is unavailable for the PLC:
Inspect nearby Matics access points.
Ensure strong Wi-Fi coverage is provided to the PLC.
3. Check PLC Network Settings
Use your phone next to the PLC and search for a network similar to
“HF-A21x_Ap” or "HF-A11x_AP"
If you find this network, it indicates the PLC may have lost its network configuration.
In this case, contact Matics Support for assistance with reconfiguring the PLC network settings.
