Events as text channels
Using the "HD trend graph" in ibaQPanel, it is possible to display in the trend graph events as text channels.
Simply drag the event from the HD signal tree and drop it on the trend graph in ibaQPanel. The event is displayed in the legend with its event name. If the event occurs, an event message is displayed dynamically on the right time or length position.
The following two figures show as an example the event "Tension Uncoiler 1" in a time-based trend graph. The second figure shows a zoomed presentation of the triggering.

 |
When you only want to compile the incoming events, set the value "never" when you define the event for the "Outgoing event" (see chapter Configuring event-based HD data store ). |
Tip |
|
|---|---|
|
In order to avoid overlapping text in the display when zooming out, just disable the option "Allow text channel overlap" in the graph's properties. |
Note |
|

 |
If you run the HD trend graph in live mode in ibaQPanel and you want to display an event as text channel, it is currently urgently necessary that at least another time-or length-based analog or digital signal is displayed simultaneously. This is necessary to run the scrolling of the X-axis. |
Note |
|
|---|---|
|
All events occurring while the "Product present" signal is FALSE are displayed in the gap between the graphs. |
Pause signal
The option "Use the pause signal" exists for the time-based as well as for the length-base HD trend graph.
ibaQPanel offers the possibility to control the scrolling of the trend curves with a digital signal. If the option is enabled and a suitable profile is selected, the scrolling is stopped when the signal is TRUE. If the signal is FALSE, the scrolling continues.
For the use of a pause signal with a time-based HD trend graph, this pause signal has to be included in the HD signal tree of a time-based HD store.
For the use of a pause signal with a length-based HD trend graph, this pause signal has to be included in the HD signal tree of a length-based HD storage.
Only suitable signals are offered in the signal tree of the selection field.
