Title: Do-more ethernet modbus etc
Post by: azeotrope on April 09, 2015, 09:08:06 PM

Hello all,

I have do-more's on an ethernet loop; works fine and if I have AD drivers (like for Durapulse drives) everything is really  easy.

I have other equipment that I would like to use to supply information to on or several do more units.
I have some EH flowmeters attached through a FXA520 fieldgate

http://www.endress.com/en/Tailor-made-field-instrumentation/level-measurement/20288

The fieldgate takes HART data and makes it available through a webserver, all well and good.

I want to send this data to a DO-more I talked to the EH guys and they are not much help for non EH items; they mentioned having the PLC poll the fieldgate but I have had no luck yet.

Anyone have some ideas?

Thanks,

Tom J.

I do not have the time to study the gateway documentation to see what all it can output. It does appear that it can serve XML data from the webserver. If you can configure the webserver to serve the desired data in xml style, then you can set up your Do-More something like this:
1) OPENTCP GatewayConnection to the Gateways IP and the proper port.
2)STREAMOUT This should be a string something like this: "http://10.0.0.21:80/MyConfiguresPageData.xml
3) GatewayConnection.InQueue != 0 THEN STREAMIN to MyIncomingBufferName
4) CLOSE GatewayConnection
5) Trigger a new program/task to parse the xml data (We can help you work through this once you get the previous steps working).

What about something like this?
