(3) Scan time structure of the Redundant CPU
*1: When the CPU modules are switched from backup mode to separate mode, the CPU module in the standby system (the
RUN LED turns on) cannot execute any program.
*2: End of a program indicates the timing when the END, GOEND, FEND, or STOP instruction is executed.
