Yesterday we had an HMI release containing two new features.
The first is a method to view trend histories. Before this release a user had to use a window with a trend graphic element and a command to instruct the trend graphic which date to use for display. With the new feature a supplied window has a calendar on the left side and a trend display on the right side. The calendar indicates the days containing data for the trend and by using the mouse and clicking on a date the trend data is displayed. It is a fast and easy way to view trend histories.
The second feature is a new 'Alarm panel'. The HMI has an 'Active Alarm' window and graphic elements that can be used in user created windows to view alarm information. This new graphic element is very configurable and includes buttons for all the normal operations regarding alarms. Each button can be visible/invisible, the alarms displayed can be limited to an alarm group (or all groups), configurable colors for each field or by alarm type and many more options.
