Timer - tab of the PmaTimer object

Description:
The tab serves for the definition of the period and the way of starting the timer
Configurators:
Timer enabled at startupIf checked, then the timer is enabled and it ticks.
This configurator sets the initial value of the Enabled property.
Period [s]The period in seconds. The onTick event is triggered always after the expiration of this period.
This configurator sets the initial value of the Period property.
The period is entered in seconds but as it is of the Double type, it is possible to enter the time unit smaller than 1 second. The object is linked to the computer time that "ticks" with the maximum period of 10 ms (i.e. 0.01 second). But practically such short periods cannot be used in this object. It is also recommended not to use very small value because it puts higher performance load in the application.
From application startIf checked, then periodic starting the algorithm is performed after the application is launched regardless on the daytime.
First tickSpecifies when the first tick of the timer occurs. This configurator is visible only if "From application start" configurator is checked.
After the period - After the launch, the set period is waited for and then the first tick of the timer occurs.
Immediately after launch - After launch, there is no waiting for the set period to elapse and the first tick of the timer occurs immediately.
Considering the daytime [hh:mm:ss]Setting the daytime from which periodic execution of the algorithm starts. But it is not needed to wait for this time to come, the timer is started in the first possible multiple of the defined period. This configurator is visible only if "From application start" configurator is not checked.

History:
