(PC is master and PLC is slave). I must to read data from plc every 10 second and store it in a database. If a does not read data from PLC a have a % of error. What do you mean with "put the serial I/O into a helper app"?

Quote:put the serial I/O into a helper app A helper app is a second separate application -- in this case dedicated to sampling data. So...you'd have a GUI app for interacting with the user and a helper app. Michael _________________ RB 2009r2, OS 10.5.6, Win XP SP 3 Top timhare Post subject: Re: Menubar and serial communicationPosted: Tue May 19, 2009 9:36 pm Joined: Fri Jan 06, 2006 3:21 pm Posts: 5374 Location: Portland, OR USA Quote:I must to read data from plc every 10 second I don't see how a menu suspending events from firing will cause a problem. The data will be in the buffer when the event finally does fire. Are you timestamping the data in the database, and if so, do you really expect the system clock to be accurate enough that it makes a difference? What problem are you trying to solve? Most of these issues turn out to be nothing once you look at it closely.
