CPU Modules The main element of the ACE3600 is the CPU module. It controls the I/O modules, processes the gathered data and communicates with the outside world. The core of the module is Freescale's MPC8270 32-bit microprocessor which has extended communication capabilities, high speed core, DMA and floating point calculation support. The module includes on-board memory, communication ports, I/O bus interface and other circuits. The firmware is based on Wind River's VxWorks operating system. Module Location: The CPU is a removable module located in a dedicated slot in the RTU rack. The CPU module must be plugged into the wide slot to the right of the Power Supply module. The CPU module includes several communication ports: On Board ports: ƒ Serial 1 (SI1) - RS232/RS485 serial port (configurable) ƒ Serial 2 (SI2) - RS232 serial port ƒ Eth1 (E1) - 10/100BaseT Ethernet port (CPU 3640 only) Plug-in ports bays, where different types of ports can be installed: ƒ Plug-in 1 (PI1) - fits RS232, RS485, 10 MB Ethernet, 10/100 MB Ethernet, or Radio Modem Plug-in option ƒ Plug-in 2 (PI2) - fits RS232, RS485, 10 MB Ethernet, or Radio Modem Plug-in port option.

CPU Modules
The main element of the ACE3600 is the CPU module. It controls the I/O modules,
processes the gathered data and communicates with the outside world.
The core of the module is Freescale’s MPC8270 32-bit microprocessor which has
extended communication capabilities, high speed core, DMA and floating point
calculation support. The module includes on-board memory,
communication ports, I/O bus interface and other circuits.
The firmware is based on Wind River’s VxWorks operating
system.
Module Location: The CPU is a removable module located in a
dedicated slot in the RTU rack. The CPU module must be plugged
into the wide slot to the right of the Power Supply module.
The CPU module includes several communication ports:
On Board ports:
±
Serial 1 (SI1) – RS232/RS485 serial port (configurable)
±
Serial 2 (SI2) – RS232 serial port
±
Eth1 (E1) - 10/100BaseT Ethernet port (CPU 3640 only)
Plug-in ports bays, where different types of ports can be installed:
±
Plug-in 1 (PI1) – fits RS232, RS485, 10 MB Ethernet, 10/100 MB Ethernet, or
Radio Modem Plug-in option
±
Plug-in 2 (PI2) – fits RS232, RS485, 10 MB Ethernet, or Radio Modem Plug-in
port option.
Note: For information on the ACE3600 Ethernet port and Auto-Negotiation, see the
Auto-Negotiation Note at the end of the IP Ports (MDLC over IP) section below.
The ACE3600 CPU memory includes FLASH, SDRAM, and optional SRAM Plug-in
memory. The FLASH stores the firmware, the user application program, and the user
data. The SDRAM memory stores the temporary data. The optional
SRAM memory expansion is used for logging user data. The SRAM
data is retained using an on-board rechargeable lithium battery.
