1.4 CPU Module
The CPU (central processing unit) module houses the multi-layer PCB,
which contains the ControlWave CPU, I/O monitor/control, memory,
and communication functions. It also may include the optional
Secondary Communications Board (SCB).
The CPU module includes:
AMD Elan SC520 microprocessor running at 100 MHz
two RS-232 communication ports
one 10/100baseT Ethernet port
2 MB of battery backed Static RAM (SRAM)
64 MB of Synchronous Dynamic RAM (SDRAM)
512 KB boot/downloader FLASH
32 MB simultaneous read/write FLASH memory
transmit (TX) and receive (RX) LEDs for each communication port
Keyed run/remote/local operation switch
configuration DIP switches (described in
Chapter 2
)
Port 80 display to show status codes
You can order the CPU module with the optional secondary
communication board (SCB) for additional communication ports. See
CPU Module Configurations
