IoT & Connectivity Tips

Events   Timers and Schedulers both come with a specific Event inherited from the Thing Template: Timer ScheduledEvent Both have a Data Shape allowing to capture the timestamp of when the Event was actually fired. Events in ThingWorx are triggered when a specific condition is met. In this context the condition is met and the Event is fired when a Timer has expired or a Scheduler's time is reached. Once an Event is triggered, Subscriptions will take care of executing custom Services to react to the Event. Subscriptions   Subscriptions listen to Events and can be used to react to certain Events with running custom Service scripts. To follow-up on Timers and Schedulers, a new Subscription must be created, listening to any related Event fired. Add a new Subscription to the Thing with       As the Subscription is usually listening to the Thing that it is configured on, the Source has to be left empty. When listening to other Entities' Subscriptions the corresponding Entity can be picked in the Source Entity picker. Ensure to check the Enabled checkbox to actually enable the Subscription and allow it for executing code in the Script area. The following Script will log into the ScriptLog once the Timer Event is fired     The following Script will log into the ScriptLog once the ScheduledEvent Event is fired  

Create a new Thing using the Scheduler Thing Template. The Scheduler Thing will fire a ScheduledEvent Event when the configured schedule is fired. The event is automatically present and does not need to be added manually. Configuration   The Scheduler Configuration is quite straightforward and allows for an exact setup of schedule based on units of time, e.g. seconds, minutes, hours, days of week etc. It can be accessed via the Thing's Entity Configuration   Configuration allows for Changing the runAsUser context - in which the Events will be handled. The user will need visibility and permission on e.g. executing Services or depending Things, which are required to run the Service triggered by the Event. Changing the Schedule - in which time the Events will be fired (by default every minute). The schedule is displayed in CRON String notation and can be changed and viewed in detail by clicking on "More". The CRON String will be generated automatically based on the inputs. Schedules can be configured in Manual mode - allowing for full configuration of each and every time based attribute. Schedules can be configured for a specific time Type - allowing for configuration only based on seconds, minutes, hours, days, weeks, months or years. Below screenshots show schedules running every minute and every Saturday / Sunday at 12:00 ("Every Weekend Day").     Services   Scheduler Things inherit two Services by default from the Thing Template DisableScheduler EnableScheduler These will activate / de-activate the Scheduler and allow / disallow firing Events once a scheduled time is reached If a Scheduler is currenty enabled or disabled can be seen in its properites  

Create a new Thing using the Timer Thing Template. The Timer Thing will fire a Timer Event when the Timer's Update Rate has expired. The event is automatically present and does not need to be added manually. Configuration   The Timer Configuration is quite straightforward. It can be accessed via the Thing's Entity Configuration. Configuration allows for Enabling the Timer on Thing-Startup - whenever the Thing is started, e.g. when restarting ThingWorx or via the RestartThing Generic Service, also the Timer is enabled and will fire Events. Changing the Update Rate - in which intervall the Events will be fired (by default every minute [60000 milliseconds]). Changing the User Context - in which the Events will be handled. The user will need visibility and permission on e.g. executing Services or depending Things, which are required to run the Service triggered by the Event.           Services   Timer Things inherit two Services by default from the Thing Template DisableTimer EnableTimer These will activate / de-activate the Timer and allow / disallow firing Events once the Update Rate has expired If a Timer is currently enabled or disabled can be seen in its properties
