After migrating a SLC to a 1769-L36ERM, the Studio 5000 interface was almost unusable. I started with v24, and then changed to v30 with no improvement. I disconnected the only other device connected to the controller (PVPlus 1000) and still no improvement. It would take about 10 seconds to pull up the controller tags or to switch to a ladder view. I increased the overhead time slice from 20% to 50% and it became usable. I've never had to do this before and I'd like to understand what could possibly be going on. There is one continuous task which simply calls an event task (~4ms) and one periodic task with an 11ms period that takes about 0.5ms. Nothing crazy happening there, obviously.
