Question:<\/h3>\n

When using an Automatic Pen, what is the procedure if the attributed Tag’s data spreads across multiple Historians, that is, if the pen comes from multiple sources? From which of these comes the data chosen to be shown in E3Chart?<\/p>\n

Solution:<\/h3>\n
From version 5.0 of Elipse E3<\/a>\/Power<\/a><\/strong> on, the new concept of Automatic Pens<\/strong> has been featured at E3Chart.<\/div>\n

Up until the software’s previous version, there were only three types of pens available at E3Chart: Real Time, Historic, and Real Time & Historic (hybrid). These pens referred only to the data type that they transmit.<\/div>\n
<\/div>\n
But from version 5.0 on, you’ll be able to add one or more Automatic Pens to your project. An Automatic Pen can come from multiple sources. To set up a pen as Automatic, you’ll only need to input the vertical axis’s link, that is, the real-time portion of the pen. Therefore, you won’t need to create or set up a Query for it. Both real-time data and historic data will return automatically on demand by the server, according to the time period established on the horizontal axis.<\/div>\n
