OTL Syntax
EventSourceTerm = EventPlus.DeepMonitorChangeEventSource(Variable);Description
The OTX DeepMonitorChangeEventSource is similar to event:MonitorChangeEventSource, but with additional deep change-monitoring for variables of complex datatypes like List, Map and ByteField. The deep change-monitoring shall detect changing, adding and removing of items in Lists, Maps and ByteFields in any depth. For variables of simple datatypes, this term shall behave like event:MonitorChangeEventSource. Because DeepMonitorChangeEventSource is derived from event:MonitorChangeEventSource, the term event:IsMonitorChangeEvent shall return TRUE when the Event originates from a DeepMonitorChangeEventSource.
Return Value
The Term returns the value, see table below.
In OTX, Terms are categorized according to its return data type!
| Data Type | Description |
| EventSource | The EventSource, the changes in the value of a variable monitored. |
Properties
| Name | Data Type | Class | Default | Cardinality | Description |
| Variable | - | Variable | - | [1..1] | The variable which has to be monitored. |
OTL Examples

ByteField ByteField1 = &012345;
/// Flow
