Confirmation of system architecture

[dario_andl_nabl]

Hi,

can someone confirm/correct my block scheme from attachement?

I never had PME project with Sepam's and ION devices so I am not familiar with connecting them and using ION 7650 as gateway for 3rd party Modbus RTU devices.

Thanks in advance!

Regards,

Dario

Looks OK to me.

For each Sepam you need an external module (ACE850) for direct connection to Ethernet.

You can also use one or two gateways with the modules ACE949-2 (RS485), which I believe is a lot cheaper.

But that's just my two cents...
