I am getting out of memory error under status field on program summary page. Is this a limitation of the PLM or ISY-26? How can I determine my limitations or capacity of ISY-26. I have 38 devices, plus a Controlinc, Remotelinc and an IRLinc. Do I need to upgrade to ISY-99 for more capacity? If so, does UD have any upgrade policies to the newer ISY-99.
