PM5560 Ethernet doesn't link. Bad MAC Address.

[Miguel-Quiven]

Dear all, 

A client site has around twelve PM5560 connected thru ethernet, but five of them started having trouble with the ethernet port, and they had to restart the auxiliary power of the meters to resume the communication. After several months of restarting the meters, some of them didn't connect again.

My team did a visit to the site and I’m attaching a video and a picture of the meter.

All of these meters report a MAC address of FF:FF:FF:FF:FF:FF

All these meters have the following versions:

OS: 2.7.4

RS: 2.7.4

Language: 2.14.0

Is there any way to fix this?

The meters seems to work fine thru RS-485.

Best regards.

Hello @Ramasamy_N ,

Do you have any suggestions or actions customer can take if MAC address of PM5560 changes?

Regards,

Hi @Miguel-Quiven 

Can you confirm, is this meters are communicating through Ethernet port with default IP address (169.254.0.10) when the meter is connected directly to a laptop with same series of IP settings (isolating the customer BMS network)?

Step1: Plug the Ethernet cable directly to the meter from laptop (disconnect the customer network cable) 

Step2: Power cycle the meter and set the meter IP address as 169.254.0.10 and save. (set same series for laptop 169.254.0.xx)

Step3: Navigate the meter display to setup -> comm-> Eth and check the IP address is set to 169.254.0.10

Step4: Ping the IP address from laptop and upgrade the firmware if the meter responds for ping request. 

If yes, Pls suggest to upgrade the latest firmware v4.1.8 and check this behavior.  (https://www.se.com/id/en/download/document/PM5560_PM5563_PM5580_V4.1.8/) 

If the meter is not responding (step3 & 4), we need to replace the meters.

I'll program a visit the next week and let you know my results.

Best regards.

We've tried this and we could recover the connection to most of the meters, but the ethernet port is still with troubles. 

We'll use the serial port with this customer, because we can't make any changes to their network.

Thank you very much,

Best regards.

I am having the exact same issue, with 5 meters installed. The meters looses connection and looses there IP address, the MAC address reverts to all FF's and the IP, Subnet and gateway becomes all 255's. Firmware version is the latest version 4.1.8. Any ideas on how to resolve this yet?

Hi, 

Based on the solution that @Ramasamy_N  gave me, i made the following procedure for my case:

1) Set the ethernet port to DEFAULT and save the config.

2) Power cycle the meter.

3) Set the ethernet port to STATIC, change the settings for IP, mask and GW and save the config.

In some cases, i had to repeat these steps in order to get it working.

For the deployment where i had this problem, i opted to change the comms to serial because the ethernet port kept doing this even with the latest firmware.

I guess is something related to the ethernet port turning on and off the interface, so i suggest to check your cables and switch/router to the meter.

Best regards.

We swapped out one of the PM's with a new one. This resolved the issue as it seems there was either a firmware or hardware issue on the PM we had.

Hi, I was experiencing the exact same issue with the PM5560, unfortunately in my case, the Meter's Ethernet LED's at the rear of the meter were a constant Solid Green. I have read the user manual for the meter and it appears to be a HW issue, anytime I connected to the Meter neither of the x2 Ethernet ports recognised the connection to my laptop, so it was impossible to connect to the meter via ethernet. I have since had the Meter returned and replaced under warranty, The new pm was fitted and all is working now as it should.
