The ArchestrA Alarm Control is a graphical element you can use in your ArchestrA symbols to show current and historical alarms and events. The ArchestrA Alarm Control replaces the Alarm Viewer control and Alarm DB View control in the InTouch HMI and extends alarm visualization to the ArchestrA Graphics environment.
You can use the ArchestrA Trend Client in ArchestrA symbols to show real-time values on a chart. The ArchestrA Trend Client is delivered as part of the ArchestrA Symbol Editor.
Use the Trend Client to chart attribute current values from Wonderware Application Server and tag current values from the InTouch HMI software. This differs from the trend feature in the InTouch HMI because the Trend Client fully supports ArchestrA and can initialize a trend pen with data from a historical source such as InTouch LogHistory/LGH files or the Wonderware Historian.
