Hi guys, I have the same problem with random SF LED on CPU 315 2 DP. System worked flawlessly for 10 years and now starts to fail. We have checked power supply (replace with new one), replace all DO cards, replace IM365, replace CPU and the problem won't let go. If someone have an idea, we are here to listen. Thank you in advance. AttachmentVollert1.txt (879 Downloads) |

Please help, I tried MRES, clear/reset, power cycle and problem still there. BF2 LED blinking and SF is solid red.
