ION7550 reading measurements from another ION7650

[Mohamed.ElShazly]

Can measurements from two ION7550 meters be combined and displayed on a third ION7550 meter screen, even if the meters are not connected to a PME system?

Hello @Mohamed.ElShazly ,

The answer is, it depends. There is a lot of details missing, how are the meters connected, are there other software/devices connected to the meter, etc?

Assuming Ethernet connected meters on the same network with no firewalls and enough connections available. Yes you can do this with modbus. The 2 ION7650 meters you want to read from will be configured as modbus servers. The one ION7650 meter displaying the combined data would be modbus client. There are KBs and user guides on how to setup ION7650 meter as both modbus server and client (may be called master slave).

Then in one ION7650 meter, would develop in framework links from modbus device module to Arithmetic module where calculation would combine measurements.

If you need all ION7650 meters to read from other 2 ION7650 meters, you would need 2 connections free per meter. ION7650 meter can support having more than 1 modbus client.

Hello @Mohamed.ElShazly ,

Then you should be able to setup modbus mastering on ION7650 meter to do what you are wanting.
