AC450 PM511V16 CPU unlisted halt codes
We have a customer that has experienced problems with CPU PM511V16. At two occasions the CPU’s have halted showing unknown halt codes and would not start up again. The CPU’s are installed in an AC450RMC multiprocessor system of the latest version. The CPU’s in question was installed in the same position
In 2015 the first CPU halted. It was probably PR:G. After the first halt they did not notice the halt code. When trying to initiate they got halt code “U1”.
In 2018 the second CPU halted. This one is PR:G. After the first halt they got halt code “07”. When trying to initiate they got halt code “57”.
Can anyone tell us what halt code “57” and “U1” means?
