Introduction

With the Event Library OTX offers a system for the detailed control of events to interact with the outside world. We distinguish between events that are outside the diagnostic sequence. Example, click the user or expiration of a timer and which occur within the sequence. Example, change a variable. The event handler in OTX is always synchronous and asynchronous never. This means that a mechanism is used, waiting for the occurrence of events and processes them sequentially on.

In the Event Library, the following are provided:

• Event Source

  Generation of events

• Event

  Is generated by event source and encapsulates all the information about the event.

• WaitForEvent

  Synchronization point - an ongoing diagnostic sequence is halted and waiting for certain events.
