What may have caused this issue?<\/p>\n<p>&nbsp;<\/p>\n<\/div>\n<h2 align=\"justify\"><b>Solution:<\/b><\/h2>\n<div align=\"justify\">This happens because the E3Server hardkey only accepts a limited number of I\/O points; when the application reaches this number, the subsequent tags will not communicate. (In spite of that, communication with the other tags is not affected.) On the other hand, an E3Studio hardkey has no limit of I\/O points; this means that this will not happen when you use the Studio hardkey. So, this issue will likely only have taken place because the tags can&#8217;t communicate with the E3Server hardkey after a certain limit has been reached, and not because of any other technical limitations.<\/div>\n<div align=\"justify\"><\/div>\n<div align=\"justify\">One way to work avoid this situation is to always make sure you check the number of licenses allowed and in use in the domain.\u00a0 To do so, open the <strong>E3 Admin &#8211; Licenses<\/strong> window, as seen below.<\/div>\n<div align=\"justify\"><\/div>\n<div align=\"justify\">\n<div align=\"center\"><img
