Red Cross for Meter Status on EVCE Webpage

 

Product Line:

  • EcoStruxure EV Charging Expert (EVCE),
  • Panel Server Universal (PAS600L),
  • 3rd Party Meter

 

Environment:

  • 3rd Party Meter (Crompton SL1-01), PAS600L, and LMS

 

Resolution:

Verify the IP address and slave address in the EVCE webpage.

  • IP address should be that of the PAS600L.
  • Slave address must match the meter’s configuration.

Check the custom meter settings in EVCE Webpage.

  • Some meters may require register offsets (e.g., offset by 1).

Use a Modbus tool or the PAS600L webpage to read meter data.

  • If data is visible, the meter and PAS600L are communicating correctly.

Confirm both the LMS and PAS600L are on the same network.

  • Try pinging both IP addresses.

Disable DHCP client and manually set IP address, subnet mask, and gateway.
