will your your 800F RTU data storage FB work on a 900F controller as well?
Hi Sumit Gargav,
would your solution work on a 900F controller as well?
is the related OPC Server needed for the storage of data (disturbed communication to higher system) or is the solution covering a lack of communication between RTU and OPC?
Can the system above be an 800xA for instance? because by default 800xA does not support asynchronous communication.
Have a wonderful day,

Hello Jens,
I assume you are reffering to associated app here with - Parameter passing one,
This solution is not mine (not developed by me) but we collect useful application from different sources, shape it and share it here on great platform AKS, Anyhow answer to your question,
Would your solution work on a 900F controller as well?
It should work I don't see any issue, I have personally not tested with AC 900F but if I remember correctly this was tested with AC 700F and it was working. And ideally in Freelance until there are no limitations feature works same way across all controller(AC 7/8/9F).
is the related OPC Server needed for the storage of data (disturbed communication to higher system)?
Check comment here in associated app from Robson,"It's not needed the OPC-S Node for establish connection between Freelance Vars and an OPCClient (MSExcel), only both OPC Tunnel and OPC Gateway" So answer is NO OPC-S is not needed, OPC-gateway via Tunnel will do. I suggest get connect with Robosn via comment section in App, he might have tested or used this App with AC 900F, So you get confirmation from him.
Is the solution covering a lack of communication between RTU and OPC?
RTU(I guess AC 900F referred here!) then answer is no, but check gateway and tunnel is configured properly , Gateway is fetching data from controller and passes through tunnel(No DCOM setting are required) to client.
Can the system above be an 800xA for instance? because by default 800xA does not support asynchronous communication.
Sorry but couldn't understand this question in relation to above question, But Incase you want to get value from Freelance system into System 800xA, then best way is to use Freelance connect.
And sorry I don't have hardware/system around as I am on vacation will confirm and test once I am back in office by end of Nov,
Hope that helps...
