m340 and database connectivity

Hi all,

Is it possible to write the data words (%mw) of m340 plc with the values present in database (eg oracle) .... ?

If yes any pointers in this direction pls

If no can we do the same by using vijeo citect variable tag mapped to particular required word of PLC (%mw). Here how to read database values (which will be updated periodically say every 5min) so as to write them to variable tags ... ?

Any help is highly appreciated ....

I would use a package like AdvancedHMI. It operates in visual studio and is written in visual basic. The Modbus TCP driver is included. This means that you can connect the Ethernet port from the PLC to a computer with this package running.
I would then use visual studio to connect to your database and write to the Modbus address that you need.

Here are some links that may help.

Thanks Garry, I will look into that..

You will be able to do this with a Noe card and using Soap
I looked into this at some point and looked way to complicated. Eventually just used Citect to write to a sql db
