Hi community!

We have a asset operated thorugh a DeltaV SCADA, which also has an **AMS Device Manager** instance (both from **Emerson** ) that collects heaps of instruments health information. I'd like to check if there are any experiences **integrating Ignition (or any other non-Emerson tool) with AMS** to retrieve all that HART/FF instruments diagnostics information, directly connecting to AMS OPCServer or passing AMS info through DeltaV and then connecting Ignition to DeltaV (this -DeltaV to Ignition OPC connection- we already have). If not obvious, the purpose is to build a fit-for-purpose **instruments health information system** in Ignition.

AMS has a WebServices which exposes some of the diagnostics information, and that we can pull from Ignition, but most of the really detailed instrument info is not exposed that way, but we assume could be through AMS' OPC.

Thanks!

Disclaimer: Should be quite clear by now, but I'm no instrumentation guy...apologies to the I&C community for any non-sense!

Hi,

1. AMS DM using OPC. Yes you could connect the OPC DA or OPC UA to see diagnostic data from devices, although in practice this is not efficient, each device has many parameters (between 40-300) and the access to that data is normally via HART protocol, then you will collapse the bandwidth on the HART side.
2. Webservices queries the SQL offline database (configuration) or the Alarm list. You will need a custom driver to translate the data to Ignition
