OTL Syntax
EventSourceTerm = EventHandling.MonitorChangeEventSource(Variable);Description
The OTX MonitorChangeEventSource term creates an event source that monitors the value of a variable and an event triggers when the value changed. Event queue should start immediately as soon as the event source is created.
The case when a value to a previously uninitialized variable is assigned to count as a change event and make no mistake.
Return Value
The Term returns the value, see table below.
In OTX, Terms are categorized according to its return data type!
| Data Type | Description |

Properties
| Name | Data Type | Class | Default | Cardinality | Description |
| Variable | - | Variable | - | [1] | The variable which has to be monitored. |
OTL Examples
Boolean Bool1 = false;
EventHandling.EventSource EventSource1;
EventHandling.Event Event1;
EventSource1 = EventHandling.MonitorChangeEventSource(Bool1);

{
lane
{
