HMI update 11/29/2014

A couple of minor additions and a major addition in HMI release today.
·       A new graphic element for easier data entry for operator/users was added.
·       An issue with rotating imported WMF files causing the transparent flag to be ignored was handled.
·       At runtime, if the web server is enabled and another program is using the same port number, the web server would be prevented from listening on the port number and the program using the port number would be unknown. Now if the port number is used, an entry will be placed in the event log with the name of the program using the port number.
·       User mouse actions are point and click configurable for most actions. For the unusual requirements a script could be created and the mouse action linked to the script. Now the script (OnMouseDown and OnMouseUp) can be embedded in the graphic element, eliminating the linking step, linking is still supported.
·      When an ODBC connection attempts to connect to a database and it fails, the error message generated is now more informative about the cause of the error, i.e. invalid credentials, table not found, etc.
·       Analog host tags can now have an initial value set on runtime start.
·      The “Drop list” graphic element can now be loaded from an XLS file at runtime.
·      The recipe unit was based on using XLS files to hold/access the recipe and was read only. Now, the XLS file can be modified in the HMI, at runtime, and saved to disk. (Excel, does not need to be installed.)
·      Also, the recipe unit now supports ODBC. So, connecting to any database that supports ODBC is now supported. And as with XLS recipes, the recipe can be changed at runtime and changes are written to the database when the change occurs.

HMI update 11/06/2014...

Today we release a new graphic element in the HMI. Since the initial release the HMI has had a horizontal scrolling trend graphic element.

Now the HMI has a 24 hour circular trend graphic element. The mechanical circular trend was used for decades before strip chart recorders. Round circular trends can be very useful to see data points over an entire 24 hour period on one chart, without any data compression to format the data for display on one horizontal trend.
