5. CONFIGURATION
5.1.1.4. Project Parameters
The CPU project parameters are related to the configuration for input/output refreshing at the task that they are used of the
project tasks and consistency of the retentive and persistent area in %Q and the options for reading and writing on the memory
card.

ATTENTION
After setting the project copy possibilities and having created the boot application, it must
be found the “Application.crc” file in order the configurations concerning the memory card
have effect. The search can be done at Select the Application.crc through the Find File... key,
as can be seen on Figure 136.
5.1.2. External Event Configuration
The external event is a feature available in the CPU which enables a digital input, configured by the user, when activated,
triggers the execution of a specific task with user-defined code. Thus, it is possible that through this input, when triggered,
interrupt the execution of the main application and run the set application in the task ExternInterruptTask00, which has higher
priority than other application tasks. Because the inputs and outputs are updated in the context of the MainTask task, the
External Event task does not have the input and output data updated at the time of its call. If necessary, use the I/O update
functions.
It is also important to note that, to avoid the generation of several events in a very short space of time, that was limited
the treatment of this type of event in every 10 ms, i.e., if two or more events occurs during 10 ms after the first event, the
second and subsequent events are discarded. This limitation is imposed to prevent an external event that is generated in an
uncontrolled way, do not block the CPU, since the task has a higher priority over the others.
