METSEPM5340 freezes and we lose communication

[Youssef-asec]

metsepm5340 meter freezes and loses communication,and when we cut power then energize power to meter,it works correctly but then repeats the same issue.

we have 6 meters connected to unmanaged switch

Hello @Youssef-asec ,

When meters stop responding, have you tried to connect directly to meter not through the network?

Regards,

no, meter screen also freezing 

i tried to test communication through PC cmd command and it was ok 

why when i restart power supply on meter it works well again ?

maybe this information help you 

the registers i take for communication is only about 60 registers

and I have two devices to recieve data from meters ,one for plc and the other for scada 

meter power supply is 110 V DC

Hi @Youssef-asec,

Do you have IMGP traces in your network? This could potentially be causing the issue. Try enabling IGMP snooping in an upstream switch if possible.

Also, which firmware version are your meters running?

Hi @Jesus_Diaz 

we are using an unmanaged switch using different ips for each meter so we dont have the IMGP snooping option.

We are using firmware 2.1.5

We are using an unmanaged switch and each meter with a unique IP address so we dont have the IGMP snooping option.
Meters firmware version is 2.1.5

1-      PLC and two separate SCADA Stations are pulling data from the meters

2-      We are pulling data real time, approximately 250-500ms

Data being pulled are :

-Active Power

-Reactive Power

-Apparent Power

-Average Current

-Average Voltage (Phase and L-L)

-Current Phase A-B-C

-Voltage Phase A-B-C

-Voltage L-L (A-B, B-C, C-A)

-Frequency

-Power Factor

-thd current (A,B,C)

-thd Voltage (A-N, B-N, C-N)

-Active Energy( Delived to load, received from load, delivered+ rec, deliverd- received)

-Reactive Energy( Delived to load, received from load, delivered+ rec, deliverd- received)

-Apparent Energy( Delived to load, received from load, delivered+ rec, deliverd- received)

Hi @Youssef-asec,

I suggest contacting your SE country support. This may require a deeper investigation.
