The Events Counter system object is designed for counting the specified types of events on the specified objects. Unlike other objects in the Hardware tab, this object is not a hardware component, and fulfils auxiliary functions in programming the Axxon PSIM system. It is most commonly used together with other system components, since it does not have a separate interface box for data input/output.
The counter notifies the system about the collected statistical data using the “Data Collected (SIGNAL_POINT)" message. Two notification modes are available: for a specified period of time and for a specified number of events. In the first case, the notification is issued upon expiration of a set time period after the start of counting. In the second case, the notification is issued when a certain amount of events has been counted.
An option for conditional count reset is available. Two reset modes are available: for a specified period of time and for a specified number of events. In the first case, the counter is reset upon expiration of a set time period after the start of counting. In the second case, the counter is reset when a certain amount of events has been counted. After resetting the statistic, the counter issues the “Counters have been reset (COUNTERS_FLUSHED)” message.
The start time for counting can be set manually, or automatically according to the last change of the Events Counter settings.
Besides, one Events Counter object allows setting a separate counter for each event.
