Sorry for all the questions today.
After changing to 3.99y from 3.99x - by basicButtons that were using the "Toggle" feature have ceased to work.
I tried to remake the buttons - but they still do not seem to toggle the bit in the PLC. I searched for this but didn't find any results. I have trouble imagining this would be broken: is there something new I'm missing?
I'm using MicroLogix.
