Trend Error.

The underscore in '_Trend' gives me the idea that Citect Runtime cannot find _Trend.RDB, not Trend.DBF

Make sure your main project is active and selected in Citect Studio (or Citect Explorer for older versions) and that it stays selected when you run Citect. Recompile the main project if needed.

Hi Patrick. All Citect Servers (IO Server, Report, Alarm..) are running. I have recompiled and packed and Main Project is selected. So, I don't know.

I wouldn't expect the runtime to start up if it can't find a project database like _TREND.RDB. It is possible the message is from a custom Cicode function in your project. You may have to use the Find tool in the Studio to search all your Cicode for RDBOpen or _TREND.

The problem appeared on changing an included project. I removed it, compiled and it ran. I added and compiled again, I restarted and it is OK now.

Thanks everybody, anyway.
