1-2 / Introduction CI-ControlWave XFC
• ControlWave XFCs are compatible with Bristol Babcock’s TeleFlow-series in software
and networking solutions for SCADA and EFM (Electronic Flow Meter) data
editing/management, and are similar in all operations.
ControlWave XFC explosion proof gas flow computers are furnished in an explosion proof
enclosure. In addition to the explosion proof case (enclosure), the gas flow computer
hardware is comprised of an internal Function Module and either a Multivariable
Transducer (MVT) or a Gage Pressure Transducer (GPT) that is mounted on the bottom of
the enclosure. The Function Module consists of a CPU Board, System Controller & I/O
Board, an LCD Display Module, a Terminal Plate Assembly, and mounting hardware.
Sharp’s LH7A400 System-on-Chip Advanced RISC Machine (ARM) microprocessor with 32-
bit ARM9TDMI Reduced Instruction Set Computer (RISC) is the core of the CPU Board. In
addition to the microprocessor and control logic, the CPU Board includes 2MB of battery
backed Static RAM (SRAM), 512kB Boot/Downloader FLASH, 8MB simultaneous
read/write FLASH, SPI I/O Bus, Serial Real Time Clock, Display Interface, and three
Communication Ports [a 3-wire RS-232 Local Port (COM1), a 7-wire RS-232 Network Port
(COM2), and a 2-wire RS-485 Network Port (COM3)].
