Figure 3-1. MicroNet Simplex System Diagrams
3.1.1—Single CPU Options
The MicroNet Simplex control system offers a single CPU module that must be located in slot A1 of the
main chassis. Different CPU options may be selected to run the system.
The CPU5200 module offers high processing capability in a PowerPC MPC5200 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.
The Pentium CPU module offers high processing capability with single Ethernet and dual RS-232 serial
ports. The Pentium CPU operating temperature limits are 0 to 50 °C.
The Motorola 68040 CPU module offers basic capability and one RS-232 serial port.
3.1.2—Redundant Power Supplies
Two load sharing power supplies provide redundant power to the motherboard, CPU and I/O modules. The
chassis consists of three sections where the 1
st
section is reserved for either (1) or (2) power supplies. The
MicroNet Simplex power supplies are 3-slot wide each and are located together at the left side of the
chassis.
