How the data is stored
Short term data like piece counters are stored in the remanent variable of type exAssetIntLinkType . This structure is used for cross function block communication. The short term data will survive a power off but not a cold reboot.
All long term data is stored in a ring buffer consisting of individual files on the user partition. Data on this user partition will survive restarts and even program updates and be backed up if necessary. Each file contains one event. An event can be a production state, job or shift change or a downtime event. The total number of stored events can be adjusted with the constant CORE_EVENT_NUM_MAX . Keep in mind that all events must be loaded on boot-up which can take some time. As a ball park figure, it takes about 4 seconds to load 100 events.
