ControlWave Express Instruction Manual (CI-ControlWave Express)
This manual focuses on the hardware aspects of the ControlWave
Express Remote Terminal Unit (RTU). For information about the
software used with the ControlWave Express, refer to Getting Started
with ControlWave Designer (D5085), the ControlWave Designer
Programmer's Handbook (D5125), and the online help in ControlWave
Designer.
This chapter provides an overview of the ControlWave Express and its
components and details the structure of this manual

ControlWave Express is designed to perform as the ideal platform for
remote site automation, measurement, and data management in process
control and manufacturing. Typical process inputs used by the
ControlWave Express are pressure, flow, level, temperature and
frequency input [typically used for positive displacement (PD)], turbine,
or ultrasonic meters. In some cases, inputs may also be derived from
external multivariable transmitters using either the BSAP or Modbus
protocols. When mounted in a suitable enclosure, you can operate the
ControlWave Express in a protected outdoor environment.
 Exceptional performance and low power consumption through use
of the ARM microprocessor
 Very low power consumption to minimize costs of solar panel /
battery power systems
 Three CPU / System Controller board configurations (see Table 1-
1.)
 Three process I/O board configurations (see Table 1-2.)
 Small size (enabling panel- or DIN-rail mounting installations)
 Two RS-232 and one RS-232/RS-485 asynchronous serial

communication ports

 Optional 10/100 MB Ethernet port
 Optional Display/Keypad
 Wide operating temperature range: (-40 to +70C) (-40 to 158F)
 Battery backup for Static RAM (SRAM) and real-time clock.
