Logger
2 types: summarized logger, time logger
for each logger, there is the possebility, to log the summarized kpi over the complete production time or every x seconds (time intervall)
the results of the time intervalls, where saved in an extra sub folder
for each type, each instance is logged and also an average of the instances is calculated
important: Only tasks with the logging type: “logging” are considered
the kpi’s are based on:
A Hierarchical structure of key performance indicators for operation management and continuous improvement in production systems
