
If the CPUs do not have the same application, CPU1 (located in slot A1) will
become the SYSCON and start up in the SIMPLEX mode (see section Only
One CPU) with the Backup failed flag set to TRUE. (see picture of
CHAS_STAT block)
Single CPU operation (Simplex)

If only one CPU is started (or the second CPU is started 20 seconds after the
first CPU) this CPU will start up in the SIMPLEX mode.

When this occurs the CPU (in A1 or A14) will remove the WATCHDOG then
wait 20 seconds for the second CPU then continue with normal SYSCON
start-up of initializing the I/O and running the real-time application.

When the 2nd CPU is started, it will determine the other CPU is running and
ask the SYSCON to allow it to sync-in.

The SYSCON CPU will communicate with the BACKUP and if the BACKUP
has the EXACT same application and is functioning properly, the SYSCON
will allow the BACKUP CPU to sync.

If the BACKUP syncs in correctly, the backup fault indication in the GAP will
go FALSE (see Figure 2-7).

2.4.2—Simplex Power Supplies
Single power supply provides power to the motherboard, CPU and I/O modules.
The MicroNet Plus power supply is 2-slot wide and are located at left end of the
chassis in the designated PS1 slot.
2.4.3—Single CPU Options
The MicroNet Plus control system may be used in simplex mode with a single
CPU5200 module that must be located in slot A1 of the main chassis. No other
options are available.

The CPU5200 module offers high processing capability in a PowerPC 5200
processor with features like dual Ethernet, dual Real Time Network ports, dual
CAN, and a configurable RS-232/RS-422/RS-485 serial port. Module operating
temperature limits are –40 to +85 °C.
