Now I know you want to use LOnwork.
Do know one Lonwork converter only for 128 indoor unit and max in one system you can Max up to 4 converter. You need to plan well.
But the more important now you should print the Lonwork interface specification from the VRF member page.
You need to pass to the system designer can his interface with our system. In that document mention the point that he can take to control and monitoring our system. Please do this immediate to avoid trouble.
Snice the convertion in Xif file. FGA cannot further know the level and FGA cannot training over this level. But set up lonwork, we can train in FGA office.
AS for below detail, please let me come back after my trip.
First send the interface specification now.
