T Gibbs Member OP T Join Date Jun 2012 Location Morristown, TN Posts 406 Nov 22, 2017 #4 We have an S5 that will not go into run. We think the fault is DB1-FE. Any idea what this would be?

T Gibbs Member OP T Join Date Jun 2012 Location Morristown, TN Posts 406 Nov 22, 2017 #6 We did that, several times. We have reloaded the program, changed the CPU, changed the backplane, etc. it still acts the same way

sigmadelta Member S Join Date Apr 2016 Location From Canada - Living in Bulgaria Posts 2,010 Nov 22, 2017 #8 Is COLD RESTART an option in STEP 5? I assume you have a CPU 928B.
T Gibbs Member OP T Join Date Jun 2012 Location Morristown, TN Posts 406 Nov 22, 2017 #9 Yes, we tried cold restart
sigmadelta Member S Join Date Apr 2016 Location From Canada - Living in Bulgaria Posts 2,010 Nov 22, 2017 #10 Since you've been changing CPUs and reloading the program etc... What happens if you clear the CPU memory and put it in RUN? DO you have an EPROM installed?

T Gibbs Member OP T Join Date Jun 2012 Location Morristown, TN Posts 406 Nov 22, 2017 #12 Do not have eeprom. We have RAM on this one
T Gibbs Member OP T Join Date Jun 2012 Location Morristown, TN Posts 406 Nov 22, 2017 #13 This is second screen of I stack
T Gibbs Member OP T Join Date Jun 2012 Location Morristown, TN Posts 406 Nov 22, 2017 #14 B stack will not show anything
