Every time the CompactLogix processor I'm working with loses power and comes back, the processor has a major fault (type 01, code 01). The fault description is "Power lost and restored in RUN mode". How can I disable this fault? The processor should just return to run mode. |

It turns out that the controller program had a power-up event handler created for it. If you have a power-up event handler, you need to have that handler automatically reset the power-up fault. In my case, the event handler wasn't doing anything, so I just removed it. (Note that I had to go into the controller properties to do this - you couldn't do it by hitting the delete button on the program itself, which was a bit confusing.) |
