FB_TrendHmi

Support class for the TwinCAT HMI SQLiteTrend with pre-implemented views. The TF8550 function TcHmi.Functions.Plastic.UpdateTrend() is required for use. The selected view is additionally determined by the property SelectedView. The following objects with corresponding interface can be attached to the trend:

Type	Display value
I_ExtruderHmi	Actual turnrate of the extruder [RPM]
I_MonitoringHmi	Monitoring value [any]
I_TempChannel	Actual temperature of a temperature channel [°C]
I_Temperature	Actual temperature of each grouped temperature channel [°C]
I_TempCtrlHmi ¹	Temperature of each zone [°C]

¹ Obsolete

Internal functions:

The first x views are pre-reserved for displaying the temperature groups

Default x := 5
Automatically adapting to the set number of groups
When the FB_Temperature group configuration is changed, the views are automatically adapted as well

All values attached via Append() are available for configuration by the ConfigXyz() methods

Syntax:

FUNCTION_BLOCK FB_TrendHmi EXTENDS FB_Base
