Which they solved by, programming in Visual Basic (once Citrix didn’t run properly), through the PI system, with PI ProcessBook, screens of their problem and preventive maintenance alerts. They were so able to signalize individual and groups of tags with alarms and trends. By this action, they achieved: Loading arm downtime in more than 700 hours/year; More than 2% increase in their production capability; More than $ 1 MM/year savings in maintenance. All of this, by the use of only 8000 tags."
