Logic/Configuration Source And Cpu Operating Mode At Power-Up - GE PACSystems RX7i Reference Manual

Chapter 4. CPU Operation
4.7 Logic/Configuration Source and CPU Operating Mode at
Power-Up
Flash and user memory can contain different values for the Logic/Configuration Power-up Source
parameter. The following tables summarize how these settings determine the logic/configuration source
after a power cycle. CPU mode is affected by the Power-up Mode, the RUN/STOP Switch and Stop-Mode
I/O Scanning parameters, the physical RUN/STOP Mode Switch position, and the Power Down Mode as
shown in sections 4.7.1 and 4.7.2.
