Connecting to an ACM 3720 with ION Setup Via Modbus

[kurtis_eisl_ca_]

End user is looking to setup a pulse output on an existing ACM3720 Power Meter. Can this be done via ION Setup by connecting to the ACM3720 over Modbus RTU through a Com'X?

Is there another way to setup the realy outputs to send a pulse?

Hello Kurtis,

The ACM3720 meters are old. I found a document for some reference. https://www.se.com/ww/resources/sites/SCHNEIDER_ELECTRIC/content/live/FAQS/212000/FA212861/en_US/372...

It may be possible to program the relays but this is not something done via ION Setup. Starting on page 14 of the second link shows how to program the meter via modbus writes.

Thanks Charles I have read both documents. As the ACM3720 is supported in ION Setup we had (hoped) that it could be ready through an Ethernet Gateway (Com'X) to program the relays; however it appears that ION Setup will only support in via PML protocol.

Thanks for the reply.
