3.82 connection lost
« on: November 18, 2014, 08:30:01 AM »
Hi, I installed new version 3.82 with same page of a 3.8 version that works fine.
I every control that I have in a page I see "Com error. Send que full, may have lost connection or data request too fast".
I use ethernetIPforCLX driver and every page I have 2 driver: one with 1second poll rate and one with 0,5s poll rate

Are you performing any read/writes in code?

No I only use controls without using direct reading or writing tags in my code.
The problem seems be present in pages with a lot of controls

You can also try going to line 931 in EthernetIPforCLXcom.vb and removing the "Begin":
Code: [Select]
Me.Read(GroupedSubscriptionReads(i).TagName, GroupedSubscriptionReads(i).NumberToRead)

I posted a version 3.83 that uses a different method of updating subscribed data. This should prevent the issue of "Send Que Full" and also distribute the communications over the poll rate.
