Since connecting Ignition to our existing 1756 - DHRIO rack, if one of the nodes is dropped, as in the PLC was turned off for a day. The node does not reestablish connection when the PLC gets turned back on. Is there a best practice available? I have turned the poll rates down quite a bit. Nothing under 10 seconds, to prevent traffic issues. Also am polling the same rack with Wonderware Historian - soon to be removed System: 1756 EN2T 1756 DHRIO 7 cards - various firmware levels from 2.x to 6.x Thank you[.](https://apksprofree.com/) regard apksprofree ---

I have a similar issue. I have been going to config and telling them to reconnect because they do not reconnect automatically. 8.1.19 ---
