I have a ControlLogix Logix 5555 1756-L55/A [1756-M13/A]
I had a program in it when I left Friday Afternoon and no ones else around.
I came back to it this afternoon to do some more programming and found the following condition
Run Status = Green
RS 232 Status = Solid Red
Ok Status = Solid Red
I shut the power off and hooked up the laptop to it than started it
At the Start up the following occurs
Ok Flashing Red than goes Green
RS 232 Flashing Green
I am Connected but once the processor goes into run both the RS232 and OK Status goes solid red.
Was able to see a fault stating that there was no program in the Processor
Just what happen??
Anybody have any thoughts on this one??
Thanks
