Brian,
<div class=""><br class="">
</div>
<div class="">Did we had firmware on the torus power supply changed recently? Could it be that after the change someone restarted/rebooted the whole system with a different PLC code?</div>

<div class="">Thanks, Stepan<br class="">

So far I've only found 3 actual code differences (one is a missing tag, the other a disabled interlock [both already changed online], the other is a tag to potentially bypass the hardware timer [set to 0 in the old code so leaving it out for now]).</div>
